I am having a problem with my kvm resource. It was working until I decided to
re-install the kvm machine. The libvirt xml file and the pacemaker
configuration did not change. I can start the kvm outside of pacemaker just
fine. When I check the libvirt log, it shows no attempt to start the kvm
machine from pacemaker.
crm_mon -1 shows:

My other kvm machine with the same config works just fine.
I can't tell you why it doesn't work anymore, but...
my logs are at: http://pastebin.com/peFw5KKp
The relevant bit of that log is (pardon the formatting):
Nov 1 03:14:37 admin01 crmd: [15349]: info: te_rsc_command: Initiating
action 4: monitor convirt-kvm_monitor_0 on admin01 (local)

So the probe (and presumably subsequent stop) for that resource failed,
hence no attempt to start it. As for how the state file is empty, I'm
not sure. Look at VirtualDomain_Define() in
/usr/lib/ocf/resource.d/heartbeat/VirtualDomain (line ~200 onwards), by
my reading it shouldn't be possible for that state file to be empty.
Unless, somehow (wild guess), permissions on the state file or some
parent directory prohibit writing?
