[libvirt] [PATCH v6 02/13] qemu: Detect support for vxhs
Using the query-qmp-schema introspection - look for the 'vxhs'
blockdevOptions type
Signed-off-by: John Ferlan <jferlan(a)redhat.com>
---
This is new from v5, this is the way I figured out in order to
use the query-qmp-schema in order to determine if 'vxhs' was
possible. It sets the libvirt capability.
