oVirt configuration

Testbed

Based on oVirt red hat blog

• oVirt Hosts: kvm04.lcg.cscs.ch and kvm05.lcg.cscs.ch
• oVirt Engine: xen01.lcg.cscs.ch
• NAS mountpoint: nas.lcg.cscs.ch:/ifs/LCG/vm/ovirt mounted on kvm04:/ovirt and kvm05:/ovirt

• The oVirt Engine system is to be created as a VM running in HA on either of the kvm04/kvm05 hosts. All other VMs need to be configured to run on the local SSDs.
• All systems involved, oVirt-Hosts, oVirt-Engine and oVirt-VMs are to be configured using PUPPET only. CFEngine systems will NOT be ported to this virtualisation system.

Installation

• Puppet: Contents of kvm04.lcg.cscs.ch.yaml.
