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

[Eitan Raviv]

Hi Sandy,

Can you elaborate some more about the steps you have taken?

Specifically, how\where do you apply cloud-init-0.7.9-20 rpm? Can you make
sure that rpm -q cloud-init after VM reboot is still this one?

How do you apply the static IP settings that do persist to the VM - via
oVirt web-admin\REST API\other?

When you restart the VM via oVirt GUI - do you 'Run' it or 'Run Once'?

Thanks,
Eitan
