Additionally since libvirt supports QAPI introspection, this means we
are now able to detect whether qemu supports vxhs and should report an
error if it doesn't.
You'll need to add a capability bit in qemu_capabilities.h and the detection
string in qemu_capabilities.c to virQEMUCapsQMPSchemaQueries[].
