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. > And can you detail your test case?

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. Kind regards, Pavel Fedin Expert Engineer Samsung Electronics Research center Russia
