This is a non-essential feature. I just hit a backtrace when trying
to refresh XML. It's fixed by the previous patch, but we should avoid
these errors from killing the create.py wizard at least.
It's really a useless hold over from the days when we manually talked
to HAL.
One semi useful bit lost in the shuffle is the option to repoll cdroms
for media. But since virt-manager allows attaching a device to the
VM regardless of whether it notices media change, this plumbing is
really overkill. If libvirt ever grows nodedev events we will get this
much easier.
