Steps: Following steps of Description. We tested with Live migration with ovs+vhost-user+dpdk scenarios. Reproduced with openvswitch2.11-2.11.0-39.el7fdp.x86_64: # /bin/virsh migrate --verbose --persistent --live rhel7.8 qemu+ssh://10.73.72.196/system Migration: [100 %]error: internal error: qemu unexpectedly closed the monitor: 2020-02-05T11:10:10.812975Z qemu-kvm: -chardev socket,id=charnet1,path=/tmp/vhostuser0.sock,server: info: QEMU waiting for connection on: disconnected:unix:/tmp/vhostuser0.sock,server 2020-02-05T11:10:10.941050Z qemu-kvm: -chardev socket,id=charnet2,path=/tmp/vhostuser1.sock,server: info: QEMU waiting for connection on: disconnected:unix:/tmp/vhostuser1.sock,server 2020-02-05T11:10:25.970886Z qemu-kvm: VQ 0 size 0x400 < last_avail_idx 0x5e93 - used_idx 0x7d6c 2020-02-05T11:10:25.970918Z qemu-kvm: Failed to load virtio-net:virtio 2020-02-05T11:10:25.970936Z qemu-kvm: error while loading state for instance 0x0 of device '0000:00:06.0:00.0/virtio-net' 2020-02-05T11:10:25.973035Z qemu-kvm: load of migration failed: Operation not permitted Verified with openvswitch2.11-2.11.0-47.el7fdp.x86_64: Migration works very well. No any error. # /bin/virsh migrate --verbose --persistent --live rhel7.8 qemu+ssh://10.73.72.196/system Migration: [100 %] Note: Testpmd cmd in guest, testing with "--iova-mode va". /usr/bin/testpmd \ -l 1,2,3,4,5 \ -n 4 \ -d /usr/lib64/librte_pmd_virtio.so \ -w 0000:06:00.0 -w 0000:07:00.0 \ --iova-mode va \ -- \ --nb-cores=4 \ -i \ --disable-rss \ --rxd=512 --txd=512 \ --rxq=2 --txq=2 So this bug has been fixed very well.
We also tested rhel8 version, this issue has been fixed well too. openvswitch2.11-2.11.0-47.el8fdp.x86_64 works well
