Modify the guest libvirt XML to add the virtio-serial channel:
<channel type='unix'>
<source mode='bind' path='/tmp/socket'/>
<target type='virtio' name='org.libguestfs.channel.0'/>
</channel>
In the guest, compile guestfsd and run it like this:
sudo daemon/guestfsd -rv
(XXX - should current directory be / ...?)
Yeah, I think it makes sense to have it chdir(/) so that
it doesn't accidentally cause a random FS to remain busy.
In the host connect using:
sudo guestfish -d GuestName --live
><fs> run
><fs> ll /
etc.
I think this series all looks fine. Obviously the main implication you
mentioned before is that we'll need to be strict about the RPC wire
back-compat support from this point forward.
Also need a init script (or systemd unit) to start the guestfsd if-only-if
it sees the virtio socket present inside the guest.
