That sounds just fine.
You must not enable autostart of the VMs on either host, so i.e. keep the 
configs elsewhere than /etc/xen/auto (iirc).
You should put in some extra effort to keep the configs in sync, i have in the 
past used csync2 for that.

It might be an outdated solution, i searched quickly and found this:
"From SUSE Linux Enterprise 15 onward, we use lvmlockd as the LVM2 cluster 
extension, rather than clvmd. Make sure the clvmd daemon is not running, ..."

Maybe you can find something in that direction.
