In our cloud, we generate MACs with the prefix 2c:c2:60
for instances.
When we re-use an instance, or duplicate it, the new copy gets another MAC address.
When the new copy boots, the NIC gets the name eth1 due to the new MAC.
I see that in /lib/udev/rules.d/75-persistent-net-generator.rules
, there are rules for known prefixes such as 52:54:00 (KVM)
and VMWare (00:0c:29)
.
But this file should not be edited as stated in its first line.
We would like to use our own registered MAC prefix and not others' ones.
How to disable net rules generation completely?
