[libvirt] NFS over AF_VSOCK in <filesystem>

virtio-vsock support has been added to the nfs-ganesha NFS server. I'm currently working on upstreaming virtio-vsock into Linux and QEMU. I also have patches for the Linux NFS client and server. Users wishing to share a file system with the guest will need to configure the NFS server. Perhaps libvirt could handle that given that it already has <filesystem> syntax. The basic task is setting up either the kernel nfsd or nfs-ganesha for the VM to access the NFS export(s). When the VM is destroy the NFS server can be shut down. Does this sound like a responsibility that libvirt should handle? Stefan
