Most probably you forgot to share the memory between host and guest.
in the VM xml:

E.g.:
  

  

  
...

[ovs-discuss] [ovs-dpdk] how to link between guest vNIC and dpdkvhost socket

2017-10-25 Thread Xu, Rongjie (NSB - CN/Hangzhou) 
Hi,

I have one OpenStack environment with OVS-DPDK (manually installed). I success 
to launch two VMs on two separate compute node with vhostuser interface type. 
But I cannot ping from one to another. I found there are even no packets in the 
local 'br-int' bridge (where dpdkvhostuser interface is attached). My guess is 
the link between guest vNIC and dpdkvhost socket at host side is somehow 
broken, but I do not know how to proceed. Anyone any suggestions?
