[Users] Nic names : always start by eth0

[gregoire.leroy at retenodus.net]

Hello,

I have an ovirt cluster which runs CentOS VM. I have a template to 
create VM. On this template, there are two interfaces, eth0 and eth1.
When I create a VM using this template, the new interfaces are named 
eth2 and eth3. It can be pretty annoying and I would like to know if it 
would be possible to always start by eth0 ?

If I remember the discussion on IRC, it would be necessary to clean old 
udev rules (in centos it seems to be 
/etc/udev/rules.d/70-persistent-net.rules)

Thanks,
Regards,
Grégoire
