In virtualized cluster environments (that is, clustering at the guest
level), you would need a STONITH script to talk to the hypervisor
instead (requiring you to first locate the physical node on which the
virtual DomU runs on), or if the physical node is unavailable, fence the
physical node.
This is not currently possible.
The right solution is
- Run Linux-HA/Pacemaker at the hypervisor layer as well, configured for
physical stonith
- Have the stonith plugin in the guest call out to the hypervisor layer,
setting the target_role for the guest-to-be-fenced to "stopped" and
wait until it has reached that state.
The ssh stonith script cannot do this.
