To expand on how it could be used by a libvirt client if we could wire
this up in our message reporting API.
A client app using libvirt python API would do:
msgs = dom.getMessages(libvirt.VIR_DOMAIN_MESSAGES_MIGBLOCKERS)
if len(msgs) > 0:
print("Domain %s uses features that block migration" % dom.getName())
for msg in msgs:
print(" >> %s" % msg)
Migration blockers change over time, as hardware is hotplugged/unplugged,
so this isn't a one-off thing. The list of blockers is only valid at the
point in time that it is queried.
