Hi again
I have recently rebooted KVM guests with two virtual NICs (e.g. /dev/ens4 and /dev/eth0) only to find that the device name of the eth0 changes to eth1 and so the ifcfg-eth0 doesn't match.
So I fix the ifcfg file and restart network - all OK.
On a later reboot eth1 changes back to eth0.
What is going on? Anyone else observe this phenomena?

Cheers
Bill Maidment
