The mac adress are unknown until the creation of the VM, so udev won't help here :(
But after the creation of the VM and before the first run you have the opti= on to edit/view those MAC addresses.=20 Give whatever you want before the first run.=20

Hello =20
=20
=20
My first email on the mailing, I hope the first one of a longue =20 serie. =20
=20
=20
Welcome to community :) =20
=20
=20
=20
The email concerns a Network Card order issue for which I like to =20 report a have your advises. =20
=20
=20
I've made a template which contains 2 network cards, Each one =20 bridge =20 on different vlan network. =20 When I create a VM from this template, the network card mac address =20 assignation is random... so that by default my fedora assign eth0 =20 to =20 the smallest mac address, and so on for eth1/eth2 ... =20
=20
=20
But no way to define network card order in template, so that =20 sometime =20 the smallest mac address is on eth0, sometime on eth1 (and in fact =20 more often on eth1), sometime my VM works, sometime I have to =20 destroy and recreate network interfaces. =20
=20
=20
=20
Unfortunately it's a known issue that related mostly to guest kernel =20 rather than RHEV-M. =20 This is not related to order of NICs during VM start, because RHEV-M =20 keep the MAC assignment =20 and even PCI address assignment same over VM reboots. =20
=20
The real reason hidden somewhere deep in kernel/udev behaviour. =20 We need to understand why 2 NICs with same MAC addresses and same PCI =20 addresses may get different names (eth0/eth1) =20 over machine reboot. =20
=20
Michael, any ideas? =20
=20
=20
Is there a workaround or anything else ? =20
=20
=20
No, I am not aware of any workaround =20
Wouldn't it be possible to write some matching rules in: =20 /etc/udev/rules.d/70-persistent-net.rules =20
for your template so you would have it consistent. Mind that you should =20 not rename to the kernel eth namespace. =20
Best, =20
