This is a bit of "Ask about A, get recommended B" answer, so appologies up front for that. I build 2-node KVM clusters which properly live migrate and, when a node is suddenly lost, recover the VMs on the surviving peer. I'v written a tutorial covering how to build it here: https://alteeve.ca/w/2-Node_Red_Hat_KVM_Cluster_Tutorial There is a new graphical interface, too. You can use it to manage the host nodes, existing VMs and create/delete VMs from the cluster; https://github.com/digimer/an-cdb http://imgur.com/a/YPfZu#0 It uses corosync + cman + rgmanager though, so it may not be appropriate for you.
