Hi, 

I have executed below commands:

./utilities/ovs-vsctl add-br ovsbr0
./utilities/ovs-vsctl set bridge datapath_type=netdev
./utilities/ovs-vsctl add-port ovsbr0 dpdk0 -- set Interface dpdk0 type=dpdk
./utilities/ovs-vsctl add-port ovsbr0 dpdk1 -- set Interface dpdk1 type=dpdk
./utilities/ovs-vsctl show

Please find the attachement for bridge and dpdk-port creation..

Now, If i do "ifconfig -a" the created bridge ovsbr0 is showing Broadcast Running and Multicast but ip address was not given. So i had assign an IP-address to ovsbr0 which previously Eth1 had. 

So, now I try to ping this guest machine ip address from its host.  Here is the output. 

ping 192.168.1.7
PING 192.168.1.7 (192.168.1.7) 56(84) bytes of data.
>From 192.168.1.40 icmp_seq=1 Destination Host Unreachable
>From 192.168.1.40 icmp_seq=5 Destination Host Unreachable
>From 192.168.1.40 icmp_seq=6 Destination Host Unreachable
>From 192.168.1.40 icmp_seq=7 Destination Host Unreachable
>From 192.168.1.40 icmp_seq=8 Destination Host Unreachable
>From 192.168.1.40 icmp_seq=9 Destination Host Unreachable

I believe it should be pinged from its host machine. Can please let  me know what is the issue and how to proceed.

Thanks & Regards

Hi,
Can you show the log output of OVS? and the ouput of following command
cd path/to/ovs/utilities/
 ./ovs-ofctl show br0
 ./ovs-ofctl dump-flows br0
(Assum that br0 is a bridge name that you had created)

 Hi Team,
 
 Guest machine is not pingable from Host machine after creating a bridge with datapath_type "netdev" in the configuration database and adding  dpdk ports. Can anyone please let me know what is the issue.
 
 Thanks in advance.
 
 Thanks & Regards

Oops. I see. After all the acrobatics I've done with the patches I must
have forgotten to check the compilation of this series stand alone -
shame on me!
Let me fix it and resend the patches...
