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

Hi
You have toremove HWADDR value from theifcfg-ethX and rules string
from /etc/udev/rules.d/70-persistent-net.rules files.
It'll work fine if you have only one NIC per machine.

Hi,
The easiest way is to remove 70-persistent-net.rules in your master-vm,
remove HWADDR-strings from ifcfg-eth* friles, shut it down and create
the template.
Btw, also remove your ssh-keys in your template to create unique ones
for each vm...
Regards,
René

we should add an ability to send a user script that cloud-init will run,
then basically user could put any configuration he would like.
this is not available currently, but i'm pretty sure supported by cloud-init.

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.

Just use sys-unconfig which will wipe
all machine specific data, like
network/root pw/ and then make it into a template. On each clone the
machine will need network/root pw/ etc.
