unsupport sonsole, command will return success,
and add a console in vm's xml.But this doesn't work
in qemu, qemu doesn't support these console.Add
a error output when try to hotplug a unsupport console

Otherwise it seems good, bud what about the case that you will attach
unsupported device to offline domain? It is still possible but the
domain cannot be started afterwards. You should probably take care of
that too.
Eww, i thought that before, and i have a question about attach unsupported
device to a offline domain.
If we forbid attaching a unsupported device, is it means we should also forbid
editing or defining a guest with a unsupported device?(because domain cannot
start with these settings). I thinks it will be a big work. Actually, I just
don't
know when we try to set a invalid things to a offline domain, which way we should
forbid and which way we can allow it.
If we allowed defining a guest with an unsupported device before, I think we
should only report the error when the user tries to start it.
Otherwise it would disappear from the domain list on libvirt update and the
user can't fix the problem via libvirt.
Got it and thanks a lot for your reply. I will write a v2 for forbid
cold-plug a unsupported device.
