[ovirt-users] Re: [External] : How to modify the MAC address of a bonding interface after changing the nic card

We've had a similar experience after changing a network card our hypervisor nodes. If you use NMCLI to affect the changes like mentioned above, the hosted-engine will revert to the old settings upon a reboot of the nodes... The only way to get around this in my experience is to make the networking changes from the hosted engine web interface: Compute, Host, Node, Setup Host Networks. If done this way, the changes become persistent... Hope this helps!
