[dpdk-dev] Running dpdk application inside virtual machine created on VirtualBox

[dpdk-dev] Running dpdk application inside virtual machine created on VirtualBox

[Shailja Pandey]

Hi,

I am trying to run dpdk application inside a virtual machine (Ubuntu 
16.04) deployed in Oracle Virtualbox. The host machine is also the same 
Ubuntu 16.04. I am running l2fwd application in the VM and the packets 
are being generated using pktgen-DPDK running on other physical machine. 
The issue I am facing is  that I am not able to redirect packets 
reaching the host machine to the virtual machine and hence the l2fwd 
application running inside VM shows zero packet counts. I am 
successfully binding network interfaces on virtual machine to use 
DPDK-compatible driver. I think I am missing something while binding the 
physical network interfaces to the virtual machine. Some discussion 
forum suggests using device passthrough to achieve this. I am not able 
to figure out exactly what is to be done. Any help would be appreciated.

Most virtualization environments impose network spoofing rules such
that a guest is only allowed to receive and send packets for its own
mac address.  I am not familiar with Virtual Box settings, but
there maybe a way to override this.
