[ovirt-users] Network issues with oVirt 4.2 and cloud-init

[Michael Burman]

Hi Berger,

Have you sealed the template? if you didn't sealed the template on
creation, then your new VM has the same ifcfg-eth0 settings as your origin
VM.
In order to avoid this, you need to check the 'Seal Template (Linux only)'
checkbox in the New Template dialog.

Cheers)
