Unfortunately it's a known issue that related mostly to guest kernel rather than RHEV-M.
This is not related to order of NICs during VM start, because RHEV-M keep the MAC assignment
and even PCI address assignment same over VM reboots.

The real reason hidden somewhere deep in kernel/udev behaviour.
We need to understand why 2 NICs with same MAC addresses and same PCI addresses may get different names (eth0/eth1)
over machine reboot.

Michael, any ideas?

No, I am not aware of any workaround
