Sorry, I forgot to mentions it, Yes I have this configuration two failover domain, first with host-1 on top, and other with host-2 on top.<div><br></div><div>My question is, how you guys are configuring your guests resources to failover from on hosts to another, remembering that I have same machines on two kvm hosts, i.e. kvm001 has guest001 on, and kvmsrv002 has guest001 ( It must be powered on just in fail of guest0001 on kvm001)</div>

<div>Assuming you're using libvirt to manage the VM's (guests), I'd configure them as <vm> resources in rgmanager and make them members of a failover group with the highest (shows up as the lowest priority number in the example) priority to the KVM-HOST-* you want the guest to start on (if it's available).</div>
<div></div>
<div>A couple of (example) <vm> resource I have configured in my 2-node GFS2 based KVM cluster (some of the info in the vm resource tag is actually not necessary, but I was both experimenting and playing it safe when I set this up)</div>
