Hello, i've upgraded some servers from kernel 4.4 to 4.12 - both running Qemu 2.9.1.
If i migrate a VM from a host running kernel 4.4 to a host running 4.12 i get: kvm: virtio-net: saved image requires TUN_F_UFO support kvm: Failed to load virtio-net-device:tmp kvm: Failed to load virtio-net:virtio kvm: error while loading state for instance 0x0 of device '0000:00:12.0/virtio-net' kvm: load of migration failed: Invalid argument while migrating from 4.12 to 4.4 works fine. Can anybody help? Is this expected? Greets, Stefan
