Yes, that's all correct.
The current "Xen" implementation is a mixture of Xend + direct xenstore 
accress + direct hypervisor access + inotify monitor on xm files.

Top on my wish list would be virDomainMigrate*, because migration is available 
with the old Xend driver, but not with the newer libxl.
It would probably help alot, if first those things already available via the 
old Xend would be added, since this would allow libvirt to deprecate the Xend 
part there as well.

Sincerely
Philipp
