The resource state could actually be one of starting, started, stopping, and stopped. Independent of the actual state is whether you can detect the state. (Adding complex frameworks can make this task quite hard it seems) "virsh list" which ist used to get the state relies on libvirtd (it seems to me). As libvirtd is a a super-daemon (can do "everything"), it also relies on the locking daemon, locking daemon needs a common filesystem and so on (as I indicated). One could use an external NFS server to provide the locking space, but that's still another external dependency that could halt your cluster... ...
