Hi There, Our 3 node Data center is up and running and I am populating it with the required vm's. It's a test lab so I want to provide pre fabricated environments for different users. I have already set up a CentOS box for nested virtualisation which works quite well but I would really like to group multiple machines together in to one template so that when a user deploys or chooses the template they get all the vm's together as one. Is there a way to do this in oVirt without nested virtualisation? I particularly want to provide a ceph set up with 3 nodes 1 mgmt server and a couple of clients, which I had planned to do through nested virt but believe that multiple vm's would be cleaner. Any suggestions as to how to achieve this? Any help or hints would be appreciated, BR/David

oVirt does not have a built-in grouping mechanism. You can use Ansible [1] to automate the creation of several VMs together. Another possible solution is Vagrant oVirt provider [2]. You need to watch for any resources that are shared between the different groups of VMs, you will probably share a network at the very lest, so you will need to be careful about allocation of IPs and host names. You can try using the Newton integration [3] to provide layers networks that are not shared. The is also built-in OVS support, but AFAIK its not yet mature enough. As a side note, since we were not willing to have any resources share between different oVirt instances in the oVirt CI system, we ended up creating Lago [4], which keeps everything confined to a single physical host.
