The problem is that libvirt is trying to start a remote nc session over ssh; but looking at http://libvirt.org/remote.html, it looks like ssh is the only protocol using nc in that manner (so yes, you can probably avoid the issue by using tcp or tls). Meanwhile, I think you can work around it without patching libvirt, by using this as your remote URI: qemu+ssh://user@remotehost/system?netcat=/path/to/nc-wrapper where nc-wrapper is an executable script installed on remotehost, looking like: #!/bin/sh exec /path/to/real/nc -q0 "$@"
