Another question related to this. If we shut down a VM, and the host is still shutting it down, but hasn’t done that yet. Is the MAC address available for reuse? We are suspecting we have duplicate MAC addresses in use, and this could be the culprit. Hence, we’d like to see progress in the round-robin type of MAC address lease so that the whole MAC address range is cycled through before reusing the same MAC address.
See: Network: do not reuse MAC until range is used up
