To clarify what Dan means here (which I found a bit confusing
at first :-)

When a libvirt client connects to a remote machine, the libvirt client
sends the "nc -U ..." command over ssh.  So every libvirt on any
distro that might connect to a Rawhide libvirtd must be changed to
send a "socat ..." command instead.

[Having said that, socat does look like a better alternative to the
various incompatible netcats, in the long run.]
