Can we mix and match.  Can we have some old style configs in "/etc/xen" 
for some guests while using libvirt for the rest?

I'm using the new way of doing things now but wonder what will happen if 
some day I need PCI device passthrough for one guest.  Do, I have to 
revert all guests back to the old style of config to have this 
capability for one?
