[Users] Nic names : always start by eth0

[Sven M. Geschke]

Hi

AFAIK This is more a CentOS- than an oVirt-issue. CentOS behaves identically on vSphere.

If I remember correctly, this is due to the fact that the MAC-address of the virtual NIC has to change, when you create a VM from a template.
CentOS however keeps the MAC address of the template and just adds the new MAC, which then of course becomes eth1.
