[libvirt] [PATCH 2/2] qemu: add a check when cold-plug a Chr device
Add a func just check the base target type which
qemu support. But i still doubt this will be useful
, we already have a check when we try to start the
vm. And this check only check the target type, and
the other things will be done in virDomainChrDefParseXML.
