migrate PHX router VM to oVirt

Description

All systems in infra-phx and workers-phx internal VLANs are managed by a router VM called gw01.phx.ovirt.org which offers DHCP, DNS and NAT services. It is currently running on libvirt and needs to be moved to oVirt for ease of maintenance. Also, services need to be set up to use configuration management.

Ideally, the router needs to be made highly available using VRRP, but first and foremost it needs to be moved to oVirt to re-purpose the host where it is currently running.

router moved to an HA VM in oVIrt named gw02.phx.ovirt.org

All hosts in PHX, including the Production DC now have VLANs set up on them.

Here's a quick and simple migration plan:
1) create VM on oVirt matching existing router. Assign required VLANs to it, ensure it can access all VLANs
2) schedule maintenance, put jenkins into "prepare for maintenance" mode
3) start clonezilla on both ends, copy over disk
4) set old MACs on new VM, start it, ensure services are up
5) cancel maintenance on Jenkins

A more complicated version:
1) create VM on oVirt matching existing router. Assign required VLANs to it, ensure it can access all VLANs
2) set up software and configure services using different IPs
3) schedule maintenance, put jenkins into "prepare for maintenance" mode
4) turn off old VM
5) switch IPs, start services
6) cancel maintenance on Jenkins

Done
