[Users] Migration of VMs from 2 different ovirt-managers

Hey there, I would like to start off by saying hi, as this is my first post on the mailing list :-) Here is a little background on my setup: I currently have 2 ovirt setups: 1. ovirt-vps is ovirt 3.1 with 3 Hosts and 41 VMs (distributed on those 3 Hosts) -- oVirt Engine Version: 3.1.0-2.fc17 2. ovirt-hosting is ovirt 3.2.0 with 4 Hosts and 12 VMs (distributed on those 4 Hosts) -- oVirt Engine Version: 3.2.0-4.fc18 As I understand ovirt is structured as follows: Data Center -> Cluster -> Hosts -> VMs My goal would be to just have one ovirt setup, with two clusters - so to speak I would like to create a new cluster under ovirt-hosting, lets call it vps. And migrate all the hosts from the ovirt-vps setup to that cluster. Now I have done some reading where there was talk of cold-importing VMs (aka. stop the VM on a node, export it, then import on the new node); but that would require that I: a) create a new node and b) have to turn off the VMs. Is there any way to import the hosts altogether into the new cluster, and thus not touching the VMs. Would I require to upgrade ovirt-vps to 3.2 (also upgrading all Hosts to 3.2) before doing any migration? 40 VMs on the ovirt-vps setup use using the same physical network as the VMs in ovirt-hosting; but I suppose if I create the same network (for the last VM) they would have "identical" network setups. -- Mvh Alfred Angelov
