Ah ok -- I'm not familiar enough to know when libvirt started supporting
vendor_id in XML, and I didn't look up his versions. I just remembered
being able to pass vendor_id as a command line argument months before being
able to add it into the XML... so I never implemented it (I just went
without HyperV, figuring I'm casual, and I don't want to mess around with a
CLI wrapper; virt-manager was good enough). When the entry in the XML *DID*
become supported then I added it, and ran into XML validation problems
because I added it incorrectly.
