will get error like that:
error: internal error: Nicdev support unavailable
Because there is no device address type specified in xml file, so
qemuDomainSupportsNicdev returns 'false' when invoked in
qemuDomainAttachNetDevice. Using pci as the default address type,
and assigns pci address later in qemuDomainEnsurePCIAddress.

This is almost certainly incorrect. At this point, the address should
have been already assigned. Maybe you need to look into why it wasn't.
