kvm: VQ 1 size 0x100 < last_avail_idx 0x9 - used_idx 0x3e30
kvm: load of migration failed: Operation not permitted: error while loading state for instance 0x0 of device '0000:00:13.0/virtio-net': Failed to load element of type virtio for virtio: -1
qemu-system-x86_64: Missing section footer for 0000:00:13.0/virtio-net
