I've realized one problem with this patch. It breaks virsh console
for Xen & LXC, since I've not added virDomainOpenConsole to those
drivers yet.

Supporting them is easy, but it would be a big cut+paste of the
QEMU driver code, so I think I need to re-work this to pull out
the QEMU stream code into a reusable module for other (local)
drivers to share. ESX would of course need separate code, since
that's a remote driver only.
