Dear All,
We are trying to install DPDK OVS on top of the openstack juno in Ubuntu
14.04 single server. We are referring following steps for executing the
same.
https://software.intel.com/en-us/blogs/2015/06/09/building-vhost-user-for-ovs-today-using-dpdk-200
During execution we are getting some issues with ovs-vswitchd service as
its getting hang during starting.

Also, attaching output(Hugepage.txt) of “ ./ovs-vswitchd --dpdk -c 0x0FF8
-n 4 --socket-mem 1024,0 --
--log-file=/var/log/openvswitch/ovs-vswitchd.log
--pidfile=/var/run/oppenvswitch/ovs-vswitchd.pid”
- We tried seting up echo 0 >
/sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages, but couldn’t
succeeded.
Can anyone please help us in getting the things if we are missing
any and causing ovs-vswitchd to stuck while starting?
Also, when we create vm in openstack with DPDK OVS, dpdkvhost-user type
interfaces are getting created automatically. If this interfaces are
getting mapped with regular br-int bridge rather than DPDK bridge br0 then
is this mean that we have successfully enabled DPDK with netdev datapath?
We really appreciate for all the advice if you have.
Thanks,
Abhijeet
Thanks & Regards
Abhijeet Karve

May need to setup huge pages on kernel boot line (this is example, you may need to adjust):
The huge page configuration can be added to the default configuration file /etc/default/grub by adding to the GRUB_CMDLINE_LINUX and the grub configuration file regenerated to get an updated configuration file for Linux boot.
# vim /etc/default/grub // edit file
. . .
GRUB_CMDLINE_LINUX_DEFAULT="... default_hugepagesz=1GB hugepagesz=1GB hugepages=4 hugepagesize=2m hugepages=2048 ..."
. . .
This example sets up huge pages for both 1 GB pages for 4 GB of 1 GB hugepage memory and 2 MB pages for 4 GB of 2 MB hugepage memory. After boot the number of 1 GB pages cannot be changed, but the number of 2 MB pages can be changed.
After editing configuration file /etc/default/grub , the new grub.cfg boot file needs to be regenerated:
# update-grub
And reboot. After reboot memory managers need to be setup:
If /dev/hugepages does not exist: # mkdir /dev/hugepages
# mount -t hugetlbfs nodev /dev/hugepages
# mkdir /dev/hugepages_2mb
# mount -t hugetlbfs nodev /dev/hugepages_2mb -o pagesize=2MB

Subject: [dpdk-dev] DPDK OVS on Ubuntu 14.04
Dear All,
We are trying to install DPDK OVS on top of the openstack juno in Ubuntu
14.04 single server. We are referring following steps for executing the same.
https://software.intel.com/en-us/blogs/2015/06/09/building-vhost-user-for-ovs-today-using-dpdk-200
During execution we are getting some issues with ovs-vswitchd service as its getting hang during starting.

- We tried seting up echo 0 >
/sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages, but couldn’t succeeded.
Can anyone please help us in getting the things if we are missing any and causing ovs-vswitchd to stuck while starting?
Also, when we create vm in openstack with DPDK OVS, dpdkvhost-user type interfaces are getting created automatically. If this interfaces are getting mapped with regular br-int bridge rather than DPDK bridge br0 then is this mean that we have successfully enabled DPDK with netdev datapath?
We really appreciate for all the advice if you have.
Thanks,
Abhijeet

You can still have a bridge named br-int that is backed with a userspace datapath. You can't add
a dpdkvhostuser port to a kernel space datapath. So in this case, I think you are ok and are
using DPDK.

Dear All,
After seting up system boot parameters as shown below, the issue is
resolved now & we are able to successfully setup openvswitch netdev-dpdk
with vhostuser support.
_________________________________________________________________________________________________________________
Setup 2 sets of huge pages with different sizes. One for Vhost and another
for Guest VM.
Edit /etc/default/grub.
GRUB_CMDLINE_LINUX="iommu=pt intel_iommu=on hugepagesz=1G
hugepages=10 hugepagesz=2M hugepages=4096"
# update-grub
- Mount the huge pages into different directory.
# sudo mount -t hugetlbfs nodev /mnt/huge_2M -o pagesize=2M
# sudo mount -t hugetlbfs nodev /mnt/huge_1G -o pagesize=1G
_________________________________________________________________________________________________________________
At present we are facing an issue in Testing DPDK application on setup. In
our scenario, We have DPDK instance launched on top of the Openstack Kilo
compute node. Not able to assign DHCP IP from controller.
Thanks & Regards
Abhijeet Karve

Hi Abhijeet,
If you answer below questions it will help me understand your problem.
What do you mean by DPDK instance?
Are you able to communicate with other VM's on the same compute node?
Can you check if the DHCP requests arrive on the controller node? (I'm assuming this is at least compute+ controller setup)
Best regards

Hi Przemek,
We have configured the accelerated data path between a physical interface
to the VM using openvswitch netdev-dpdk with vhost-user support. The VM
created with this special data path and vhost library, I am calling as
DPDK instance.
If assigning ip manually to the newly created Cirros VM instance, We are
able to make 2 VM's to communicate on the same compute node. Else it's not
associating any ip through DHCP though DHCP is in compute node only.
Yes it's a compute + controller node setup and we are using following
software platform on compute node:
_____________
Openstack: Kilo
Distribution: Ubuntu 14.04
OVS Version: 2.4.0
DPDK 2.0.0
_____________
We are following the intel guide
https://software.intel.com/en-us/blogs/2015/06/09/building-vhost-user-for-ovs-today-using-dpdk-200
When doing "ovs-vsctl show" in compute node, it shows below output:

Hi Abhijeet,
If you answer below questions it will help me understand your problem.
What do you mean by DPDK instance?
Are you able to communicate with other VM's on the same compute node?
Can you check if the DHCP requests arrive on the controller node? (I'm
assuming this is at least compute+ controller setup)
Best regards

HI Abhijeet,
For Kilo you need to use ovsdpdk mechanism driver and a matching agent to integrate ovs-dpdk with OpenStack.
The guide you are following only talks about running ovs-dpdk not how it should be integrated with OpenStack.
Please follow this guide:

Hi Przemek,
Thank you so much for sharing the ref guide.
Would be appreciate if clear one doubt.
At present we are setting up openstack kilo interactively and further
replacing ovs with ovs-dpdk enabled.
Once the above setup done, We are creating instance in openstack and
passing that instance id to QEMU command line which further passes the
vhost-user sockets to instances, enabling the DPDK libraries in it.
Isn't this the correct way of integrating ovs-dpdk with openstack?
Thanks & Regards

Hi Abhijeet,
If you answer below questions it will help me understand your problem.
What do you mean by DPDK instance?
Are you able to communicate with other VM's on the same compute node?
Can you check if the DHCP requests arrive on the controller node? (I'm
assuming this is at least compute+ controller setup)

I haven't tried that approach not sure if that would work, it seems clunky.
If you enable ovsdpdk ml2 mechanism driver and agent all of that (add ports to ovs with the right type, pass the sockets to qemu) would be done by OpenStack.

Hi Przemek,
Thank you so much for sharing the ref guide.
Would be appreciate if clear one doubt.
At present we are setting up openstack kilo interactively and further replacing ovs with ovs-dpdk enabled.
Once the above setup done, We are creating instance in openstack and passing that instance id to QEMU command line which further passes the vhost-user sockets to instances, enabling the DPDK libraries in it.
Isn't this the correct way of integrating ovs-dpdk with openstack?

HI Abhijeet,
For Kilo you need to use ovsdpdk mechanism driver and a matching agent to integrate ovs-dpdk with OpenStack.
The guide you are following only talks about running ovs-dpdk not how it should be integrated with OpenStack.
Please follow this guide:

Subject: RE: [dpdk-dev] DPDK OVS on Ubuntu 14.04# Issue's Resolved# Successfully setup DPDK OVS with vhostuser
Hi Przemek,
We have configured the accelerated data path between a physical interface to the VM using openvswitch netdev-dpdk with vhost-user support. The VM created with this special data path and vhost library, I am calling as DPDK instance.
If assigning ip manually to the newly created Cirros VM instance, We are able to make 2 VM's to communicate on the same compute node. Else it's not associating any ip through DHCP though DHCP is in compute node only.
Yes it's a compute + controller node setup and we are using following software platform on compute node:
_____________
Openstack: Kilo
Distribution: Ubuntu 14.04
OVS Version: 2.4.0
DPDK 2.0.0
_____________
We are following the intel guide https://software.intel.com/en-us/blogs/2015/06/09/building-vhost-user-for-ovs-today-using-dpdk-200
When doing "ovs-vsctl show" in compute node, it shows below output:

Hi Przemek,
Thank you so much for your quick response.
The guide(
https://github.com/openstack/networking-ovs-dpdk/blob/stable/kilo/doc/source/getstarted/ubuntu.rst
) which you have suggested that is for openstack vhost user installations
with devstack.
Can't we have any reference for including ovs-dpdk mechanisam driver for
openstack Ubuntu distribution which we are following for
compute+controller node setup?"
We are facing below listed issues With the current approach of setting up
openstack kilo interactively + replacing ovs with ovs-dpdk enabled and
Instance creation in openstack with
passing that instance id to QEMU command line which further passes the
vhost-user sockets to instances for enabling the DPDK libraries in it.
1. Created a flavor m1.hugepages which is backed by hugepage memory,
unable to spawn instance with this flavor – Getting a issue like: No
matching hugetlbfs for the number of hugepages assigned to the flavor.
2. Passing socket info to instances via qemu manually and instnaces
created are not persistent.
Now as you suggested, we are looking in enabling ovsdpdk ml2 mechanism
driver and agent all of that in our openstack ubuntu distribution.
Would be really appriciate if get any help or ref with explanation.
We are using compute + controller node setup and we are using following
software platform on compute node:
_____________
Openstack: Kilo
Distribution: Ubuntu 14.04
OVS Version: 2.4.0
DPDK 2.0.0

Successfully setup DPDK OVS with vhostuser
Hi Przemek,
We have configured the accelerated data path between a physical interface
to the VM using openvswitch netdev-dpdk with vhost-user support. The VM
created with this special data path and vhost library, I am calling as
DPDK instance.
If assigning ip manually to the newly created Cirros VM instance, We are
able to make 2 VM's to communicate on the same compute node. Else it's not
associating any ip through DHCP though DHCP is in compute node only.
Yes it's a compute + controller node setup and we are using following
software platform on compute node:
_____________
Openstack: Kilo
Distribution: Ubuntu 14.04
OVS Version: 2.4.0
DPDK 2.0.0
_____________
We are following the intel guide
https://software.intel.com/en-us/blogs/2015/06/09/building-vhost-user-for-ovs-today-using-dpdk-200
When doing "ovs-vsctl show" in compute node, it shows below output:

Hi Abhijeet,
If you answer below questions it will help me understand your problem.
What do you mean by DPDK instance?
Are you able to communicate with other VM's on the same compute node?
Can you check if the DHCP requests arrive on the controller node? (I'm
assuming this is at least compute+ controller setup)
Best regards

You should be able to clone networking-ovs-dpdk, switch to kilo branch, and run
python setup.py install
in the root of networking-ovs-dpdk, that should install agent and mech driver.
Then you would need to enable mech driver (ovsdpdk) on the controller in the /etc/neutron/plugins/ml2/ml2_conf.ini
And run the right agent on the computes (networking-ovs-dpdk-agent).
There should be pip packeges of networking-ovs-dpdk available shortly, I’ll let you know when that happens.

Hi Przemek,
Thank you so much for your quick response.
The guide(https://github.com/openstack/networking-ovs-dpdk/blob/stable/kilo/doc/source/getstarted/ubuntu.rst) which you have suggested that is for openstack vhost user installations with devstack.
Can't we have any reference for including ovs-dpdk mechanisam driver for openstack Ubuntu distribution which we are following for
compute+controller node setup?"
We are facing below listed issues With the current approach of setting up openstack kilo interactively + replacing ovs with ovs-dpdk enabled and Instance creation in openstack with
passing that instance id to QEMU command line which further passes the vhost-user sockets to instances for enabling the DPDK libraries in it.
1. Created a flavor m1.hugepages which is backed by hugepage memory, unable to spawn instance with this flavor – Getting a issue like: No matching hugetlbfs for the number of hugepages assigned to the flavor.
2. Passing socket info to instances via qemu manually and instnaces created are not persistent.
Now as you suggested, we are looking in enabling ovsdpdk ml2 mechanism driver and agent all of that in our openstack ubuntu distribution.
Would be really appriciate if get any help or ref with explanation.
We are using compute + controller node setup and we are using following software platform on compute node:
_____________
Openstack: Kilo
Distribution: Ubuntu 14.04
OVS Version: 2.4.0
DPDK 2.0.0

________________________________
I haven’t tried that approach not sure if that would work, it seems clunky.
If you enable ovsdpdk ml2 mechanism driver and agent all of that (add ports to ovs with the right type, pass the sockets to qemu) would be done by OpenStack.

Hi Przemek,
Thank you so much for sharing the ref guide.
Would be appreciate if clear one doubt.
At present we are setting up openstack kilo interactively and further replacing ovs with ovs-dpdk enabled.
Once the above setup done, We are creating instance in openstack and passing that instance id to QEMU command line which further passes the vhost-user sockets to instances, enabling the DPDK libraries in it.
Isn't this the correct way of integrating ovs-dpdk with openstack?

HI Abhijeet,
For Kilo you need to use ovsdpdk mechanism driver and a matching agent to integrate ovs-dpdk with OpenStack.
The guide you are following only talks about running ovs-dpdk not how it should be integrated with OpenStack.
Please follow this guide:
https://github.com/openstack/networking-ovs-dpdk/blob/stable/kilo/doc/source/getstarted/ubuntu.rst

Hi Abhijeet,
It seems you are almost there!
When booting the VM’s do you request hugepage memory for them (by setting hw:mem_page_size=large in flavor extra_spec)?
If not then please do, if yes then please look into libvirt logfiles for the VM’s (in /var/log/libvirt/qemu/instance-xxx), I think there could be a clue.
Regards
Przemek

Hi Przemek,
Thank you for your response, It really provided us breakthrough.
After setting up DPDK on compute node for stable/kilo, We are trying to set up Openstack stable/liberty all-in-one setup, At present we are not able to get the IP allocation for the vhost type instances through DHCP. Also we tried assigning IP's manually to them but the inter-VM communication also not happening,

________________________________
You should be able to clone networking-ovs-dpdk, switch to kilo branch, and run
python setup.py install
in the root of networking-ovs-dpdk, that should install agent and mech driver.
Then you would need to enable mech driver (ovsdpdk) on the controller in the /etc/neutron/plugins/ml2/ml2_conf.ini
And run the right agent on the computes (networking-ovs-dpdk-agent).
There should be pip packeges of networking-ovs-dpdk available shortly, I’ll let you know when that happens.

Subject: RE: [dpdk-dev] DPDK OVS on Ubuntu 14.04# Issue's Resolved# Getting memory backing issues with qemu parameter passing
Hi Przemek,
Thank you so much for your quick response.
The guide(https://github.com/openstack/networking-ovs-dpdk/blob/stable/kilo/doc/source/getstarted/ubuntu.rst) which you have suggested that is for openstack vhost user installations with devstack.
Can't we have any reference for including ovs-dpdk mechanisam driver for openstack Ubuntu distribution which we are following for
compute+controller node setup?"
We are facing below listed issues With the current approach of setting up openstack kilo interactively + replacing ovs with ovs-dpdk enabled and Instance creation in openstack with
passing that instance id to QEMU command line which further passes the vhost-user sockets to instances for enabling the DPDK libraries in it.
1. Created a flavor m1.hugepages which is backed by hugepage memory, unable to spawn instance with this flavor – Getting a issue like: No matching hugetlbfs for the number of hugepages assigned to the flavor.
2. Passing socket info to instances via qemu manually and instnaces created are not persistent.
Now as you suggested, we are looking in enabling ovsdpdk ml2 mechanism driver and agent all of that in our openstack ubuntu distribution.
Would be really appriciate if get any help or ref with explanation.
We are using compute + controller node setup and we are using following software platform on compute node:
_____________
Openstack: Kilo
Distribution: Ubuntu 14.04
OVS Version: 2.4.0
DPDK 2.0.0
_____________

I haven’t tried that approach not sure if that would work, it seems clunky.
If you enable ovsdpdk ml2 mechanism driver and agent all of that (add ports to ovs with the right type, pass the sockets to qemu) would be done by OpenStack.

Hi Przemek,
Thank you so much for sharing the ref guide.
Would be appreciate if clear one doubt.
At present we are setting up openstack kilo interactively and further replacing ovs with ovs-dpdk enabled.
Once the above setup done, We are creating instance in openstack and passing that instance id to QEMU command line which further passes the vhost-user sockets to instances, enabling the DPDK libraries in it.
Isn't this the correct way of integrating ovs-dpdk with openstack?
Thanks & Regards

HI Abhijeet,
For Kilo you need to use ovsdpdk mechanism driver and a matching agent to integrate ovs-dpdk with OpenStack.
The guide you are following only talks about running ovs-dpdk not how it should be integrated with OpenStack.
Please follow this guide:
https://github.com/openstack/networking-ovs-dpdk/blob/stable/kilo/doc/source/getstarted/ubuntu.rst

Hi Przemek,
We have configured the accelerated data path between a physical interface to the VM using openvswitch netdev-dpdk with vhost-user support. The VM created with this special data path and vhost library, I am calling as DPDK instance.
If assigning ip manually to the newly created Cirros VM instance, We are able to make 2 VM's to communicate on the same compute node. Else it's not associating any ip through DHCP though DHCP is in compute node only.
Yes it's a compute + controller node setup and we are using following software platform on compute node:
_____________
Openstack: Kilo
Distribution: Ubuntu 14.04
OVS Version: 2.4.0
DPDK 2.0.0

Hi Abhijeet,
If you answer below questions it will help me understand your problem.
What do you mean by DPDK instance?
Are you able to communicate with other VM's on the same compute node?
Can you check if the DHCP requests arrive on the controller node? (I'm assuming this is at least compute+ controller setup)
Best regards

Hi Przemek,
Thanks for the quick response. Now able to get the DHCP ip's for 2
vhostuser instances and able to ping each other. Isssue was a bug in
cirros 0.3.0 images which we were using in openstack after using 0.3.1
image as given in the URL(
https://www.redhat.com/archives/rhos-list/2013-August/msg00032.html), able
to get the IP's in vhostuser VM instances.
As per our understanding, Packet flow across DPDK datapath will be like
vhostuser ports are connected to the br-int bridge & same is being patched
to the br-dpdk bridge where in our physical network (NIC) is connected
with dpdk0 port.
So for testing the flow we have to connect that physical network(NIC) with
external packet generator (e.g - ixia, iperf) & run the testpmd
application in the vhostuser VM, right?
Does it required to add any flows/efforts in bridge configurations(either
br-int or br-dpdk)?
Thanks & Regards

Inter-VM communication & IP allocation through DHCP issue
Hi Abhijeet,
It seems you are almost there!
When booting the VM’s do you request hugepage memory for them (by setting
hw:mem_page_size=large in flavor extra_spec)?
If not then please do, if yes then please look into libvirt logfiles for
the VM’s (in /var/log/libvirt/qemu/instance-xxx), I think there could be a
clue.

Inter-VM communication & IP allocation through DHCP issue
Hi Przemek,
Thank you for your response, It really provided us breakthrough.
After setting up DPDK on compute node for stable/kilo, We are trying to
set up Openstack stable/liberty all-in-one setup, At present we are not
able to get the IP allocation for the vhost type instances through DHCP.
Also we tried assigning IP's manually to them but the inter-VM
communication also not happening,

Getting memory backing issues with qemu parameter passing
You should be able to clone networking-ovs-dpdk, switch to kilo branch,
and run
python setup.py install
in the root of networking-ovs-dpdk, that should install agent and mech
driver.
Then you would need to enable mech driver (ovsdpdk) on the controller in
the /etc/neutron/plugins/ml2/ml2_conf.ini
And run the right agent on the computes (networking-ovs-dpdk-agent).
There should be pip packeges of networking-ovs-dpdk available shortly,
I’ll let you know when that happens.

Subject: RE: [dpdk-dev] DPDK OVS on Ubuntu 14.04# Issue's Resolved#
Getting memory backing issues with qemu parameter passing
Hi Przemek,
Thank you so much for your quick response.
The guide(
https://github.com/openstack/networking-ovs-dpdk/blob/stable/kilo/doc/source/getstarted/ubuntu.rst
) which you have suggested that is for openstack vhost user installations
with devstack.
Can't we have any reference for including ovs-dpdk mechanisam driver for
openstack Ubuntu distribution which we are following for
compute+controller node setup?"
We are facing below listed issues With the current approach of setting up
openstack kilo interactively + replacing ovs with ovs-dpdk enabled and
Instance creation in openstack with
passing that instance id to QEMU command line which further passes the
vhost-user sockets to instances for enabling the DPDK libraries in it.
1. Created a flavor m1.hugepages which is backed by hugepage memory,
unable to spawn instance with this flavor – Getting a issue like: No
matching hugetlbfs for the number of hugepages assigned to the flavor.
2. Passing socket info to instances via qemu manually and instnaces
created are not persistent.
Now as you suggested, we are looking in enabling ovsdpdk ml2 mechanism
driver and agent all of that in our openstack ubuntu distribution.
Would be really appriciate if get any help or ref with explanation.
We are using compute + controller node setup and we are using following
software platform on compute node:
_____________
Openstack: Kilo
Distribution: Ubuntu 14.04
OVS Version: 2.4.0
DPDK 2.0.0

I haven’t tried that approach not sure if that would work, it seems
clunky.
If you enable ovsdpdk ml2 mechanism driver and agent all of that (add
ports to ovs with the right type, pass the sockets to qemu) would be done
by OpenStack.

Hi Przemek,
Thank you so much for sharing the ref guide.
Would be appreciate if clear one doubt.
At present we are setting up openstack kilo interactively and further
replacing ovs with ovs-dpdk enabled.
Once the above setup done, We are creating instance in openstack and
passing that instance id to QEMU command line which further passes the
vhost-user sockets to instances, enabling the DPDK libraries in it.
Isn't this the correct way of integrating ovs-dpdk with openstack?

HI Abhijeet,
For Kilo you need to use ovsdpdk mechanism driver and a matching agent to
integrate ovs-dpdk with OpenStack.
The guide you are following only talks about running ovs-dpdk not how it
should be integrated with OpenStack.
Please follow this guide:
https://github.com/openstack/networking-ovs-dpdk/blob/stable/kilo/doc/source/getstarted/ubuntu.rst

Successfully setup DPDK OVS with vhostuser
Hi Przemek,
We have configured the accelerated data path between a physical interface
to the VM using openvswitch netdev-dpdk with vhost-user support. The VM
created with this special data path and vhost library, I am calling as
DPDK instance.
If assigning ip manually to the newly created Cirros VM instance, We are
able to make 2 VM's to communicate on the same compute node. Else it's not
associating any ip through DHCP though DHCP is in compute node only.
Yes it's a compute + controller node setup and we are using following
software platform on compute node:
_____________
Openstack: Kilo
Distribution: Ubuntu 14.04
OVS Version: 2.4.0
DPDK 2.0.0

We are following the intel guide

Further we don't know what all the network changes(Packet Flow addition)

Would be really appreciate if have clarity on DHCP flow establishment.

Successfully setup DPDK OVS with vhostuser
Hi Abhijeet,
If you answer below questions it will help me understand your problem.
What do you mean by DPDK instance?
Are you able to communicate with other VM's on the same compute node?
Can you check if the DHCP requests arrive on the controller node? (I'm
assuming this is at least compute+ controller setup)
Best regards

Hi Przemek,
Thank you for your response, It's really provided us breakthrough.
After setting up DPDK on compute node for stable/kilo, Trying to set up Openstack stable/liberty all-in-one setup, At present not able to get the IP allocation for the vhost type instances through DHCP. Also tried assigning IP's manually to them but the inter-VM communication also not happening,

You should be able to clone networking-ovs-dpdk, switch to kilo branch, ÿand run
python setup.py install
in the root of networking-ovs-dpdk, that should install agent and mech driver.
Then you would need to enable mech driver (ovsdpdk) on the controller in the /etc/neutron/plugins/ml2/ml2_conf.ini
And run the right agent on the computes (networking-ovs-dpdk-agent).
ÿ
ÿ
There should be pip packeges of networking-ovs-dpdk available shortly, I\x0f’ll let you know when that happens.

ÿ
Hi Przemek,ÿ
Thank you so much for your quick response.
The guide(https://github.com/openstack/networking-ovs-dpdk/blob/stable/kilo/doc/source/getstarted/ubuntu.rst) which you have suggested that is for openstack vhost user installations with devstack.
Can't we have any reference for including ovs-dpdk mechanisam driver for openstack Ubuntu distribution which we are following for
compute+controller node setup?"
We are facing below listed issues With the current approach of setting up openstack kilo interactively + replacing ovs with ovs-dpdk enabled and Instance creation in openstack withÿ
passing that instance id to QEMU command line which further passes the vhost-user sockets to instances for enabling the DPDK libraries in it.ÿ
1. Created a flavor m1.hugepages which is backed by hugepage memory, unable to spawn instance with this flavor \x0f– Getting a issue like: No matching hugetlbfs for the number of hugepages assigned to the flavor.ÿ
2. Passing socket info to instances via qemu manually and instnaces created are not persistent.ÿ
Now as you suggested, we are looking in enabling ovsdpdk ml2 mechanism driver and agent all of that in our openstack ubuntu distribution.ÿ
Would be really appriciate if get any help or ref with explanation.ÿ
We are using compute + controller node setup and we are using following software platform on compute node:
_____________
Openstack: Kilo
Distribution: Ubuntu 14.04
OVS Version: 2.4.0
DPDK 2.0.0

I haven\x0f’t tried that approach not sure if that would work, it seems clunky.ÿ
ÿ
If you enable ovsdpdk ml2 mechanism driver and agent all of that (add ports to ovs with the right type, pass the sockets to qemu) would be done by OpenStack.ÿ

ÿ
Hi Przemek,ÿ
Thank you so much for sharing the ref guide.ÿ
Would be appreciate if clear one doubt.
At present we are setting up openstack kilo interactively and further replacing ovs with ovs-dpdk enabled.
Once the above setup done, We are creating instance in openstack and passing that instance id to QEMU command line which further passes the vhost-user sockets to instances, enabling the DPDK libraries in it.ÿ
Isn't this the correct way of integrating ovs-dpdk with openstack?ÿ

HI Abhijeet,ÿ
For Kilo you need to use ovsdpdk mechanism driver and a matching agent to integrate ovs-dpdk with OpenStack.ÿ
The guide you are following only talks about running ovs-dpdk not how it should be integrated with OpenStack.ÿ
Please follow this guide:ÿ

Hi Przemek,ÿ
We have configured theÿaccelerated data path between a physical interface to the VM using openvswitch netdev-dpdk with vhost-user support. The VM created with this special data path and vhost library, I am calling as DPDK instance.
If assigning ip manually to the newly created Cirros VM instance, We are able to make 2 VM's to communicate on the same compute node. Else it's not associating any ip through DHCP though DHCP is in compute node only.ÿ
Yes it's a compute + controller node setup and we are using following software platform on compute node:ÿ

We are following the intel guide https://software.intel.com/en-us/blogs/2015/06/09/building-vhost-user-for-ovs-today-using-dpdk-200ÿ

Further we don't know what all the network changes(Packet Flow addition) if required for associating IP address through the DHCP.ÿ
Would be really appreciate if have clarity on DHCP flow establishment.
Thanks & Regards

Hi Abhijeet,
If you answer below questions it will help me understand your problem.
What do you mean by DPDK instance?
Are you able to communicate with other VM's on the same compute node?
Can you check if the DHCP requests arrive on the controller node? (I'm assuming this is at least compute+ controller setup)
Best regards
Przemek
