The schema tests probably failed because you don't have xmllint installed.

Ah.  We don't support snapshots for Xen, though this is not the error you should
have seen.  You should have seen "this hypervisor doesn't support virDomainSnapshotCreateXML",
or something like that.  I'll take a look at it and see if I can reproduce.
