[...] 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[].
