Browse Source 
qemuDomainAttachNetDevice() (hotplug) previously had some of the
validation that is in qemuDomainValidateActualNetDef(), but it was
incomplete. qemuDomainChangeNet() had none of that validation, but it
is all appropriate in both cases.

This is the final piece of a previously partial resolution to
