I have ovs-dpdk setup and have spawned a VM with 2 vhost-user ports. I am
using vhost in dpdkvhostuserclient mode. If I reboot the guest vm by
issuing reboot command i am getting SEGV , looked at the stack trace , (my
guess it might be accessing old Queue memory).
is there a compatibility matrix for "vhost_net" driver used in the guest
and ovs-dpdk version.
