I have a question indirectly related to oVirt - I have a VM with CentOS 6
running on my cluster, which has 6 virtual interfaces (eth0 - eth5). Now
its a time to do an upgrade to CentOS 7 based, and I did a VM clone to test
an upgrade process and was a bit surprised to see that now I have interface
names shifted eth6 - eth11. I would afraid that I'll run out of digits
Anyway how to change the interfaces names back to originals and perhaps
prevent them form the further changes? I do understand that MAC address has
changed, but don't get why it changing the interfaces names.
Cleaning up everything from /etc/udev/rules.d/70-persistent-net.rules
doesn't really helped ..
This is a CentOS 6 old behaviour.
Except the udev rules which you need to update (I think you need to update
the mac addresses in order to keep the order), you may need to also touch
the ifcfg files if the mac address is mentioned there.
