[Pacemaker] fence_rhevm (fence-agents-3.1.5-25.el6_4.2.x86_64) not working with pacemaker (pacemaker-1.1.8-7.el6.x86_64) on RHEL6.4

Hi,
I've been trying to get fence_rhevm (fence-agents-3.1.5-25.el6_4.2.x86_64)
working within pacemaker (pacemaker-1.1.8-7.el6.x86_64) but am unable to
get it to work as intended, using fence_rhevm on the command line works as
expected, as does stonith_admin but from within pacemaker (triggered by
deliberately killing corosync on the node to be fenced):

I can get the node enterprise to fence as expected from the command line
with:

stonith_admin --reboot enterprise --tolerance 5s

fence_rhevm -o reboot -a <hypervisor ip> -l <user>@<domain> -p <password>
-n enterprise -z

My config is as follows:

The debug log output from fence_rhevm doesn't appear to show pacemaker
trying to request the reboot, only a vms command sent to the hypervisor
which responds with xml listing the VMs.

I can't quite see why its failing? Are you aware of any issues
with fence_rhevm (fence-agents-3.1.5-25.el6_4.2.x86_64) not working with
pacemaker (pacemaker-1.1.8-7.el6.x86_64) on RHEL6.4?

All the best,
/John
