There is that libvirt-bin upstart job resource but not cloned, producing
this: Resource p_libvirt-bin (upstart::libvirt-bin) is active on 2
nodes attempting recovery ... errors.
I'd say having upstart respawning libvirtd is quite fine. Removing this
primitive and therefore also from the group with its dependencies is ok.

hmmm ... heartbeat 3.0.3 is about 2 years old IIRC and there have been
some important fixes ... any heartbeat logs from quorumnode? tried using
ucast for br0/eth0?
