Currently, libvirt shows an error if a VM tries to migrate with a virtio-fs device. Since we are working on virtiofsd live migration support, and all necessary changes in our dependencies have been merged (i.e., qemu and rust-vmm), we need libvirt to allow migrating a VM if virtiofsd supports migration.

For the moment, we will only support pre-copy migration[0], and we will report it by defining it in the interop json file with:

'features': ['migrate-precopy']
