I think it should be out by the end of the month, but you know how 
predictable software development is. :-)  We just checked in a patch 
series that should make libvirt on libxl really stable (fixed a bunch of 
obscure race conditions, apparently it now runs for days of stress 
testing without any problems), so if you could get 4.4 in, that would be 
great.  (If not, I think the series may end up being backported to 4.3 
at some point, but I'm not sure.)

Yeah, long-term I think libvirt is going to be the most suitable thing 
from both sides.
