[dpdk-dev] [RFC 0/5] virtio support for container

[Pavel Fedin]

 Hello!

> First of all, when you say openvswitch, are you referring to ovs-dpdk?

 I am referring to mainline ovs, compiled with dpdk, and using userspace dataplane.
 AFAIK ovs-dpdk is early Intel fork, which is abandoned at the moment.

 vhost port. i. e.

                             |
LOCAL------dpdkvhostuser<----+---->cvio----->LOCAL
      ovs                    |          ovs
                             |
                host         |        container

 By this time i advanced in my research. ovs not only crashes by itself, but manages to crash host side. It does this by doing
reconfiguration sequence without sending VHOST_USER_SET_MEM_TABLE, therefore host-side ovs tries to refer old addresses and dies
badly.
 Those messages about memory pool already being present are perhaps OK.
