no code there that ever decreases nb_nic, so unplug doesn't seem to be
supported
Would it be worth having such a simple test in libvirt repository itself
or is that a case for the TCK project?
Yep, this is perfect candidate for a TCK test case. Take the 210-nic-hotplug.t
test case, and make it attempt to plug+unplug a NIC 35 times in a row. This
should test this particular bug, and also validate that PCI addresses are
being reused correctly (there're only 31 pci slots that can be used at any
1 time)
