[Libvir] [PATCH][RFC] libvirt ldoms support

As John mentioned, the LDoms Manager (ldm) XML interface has been
used by a different set of software such as SNMP MIB, BUI, and other
tools/applications (before the libvirt), so we can't really change
the ldm XML formats.

But, I will look into the way (conversion between the LDoms XML
and libvirt XML formats) to make it compatible with the official
