** Description changed:
+ SRU Justification:
+ [Impact]
+ * If nova-compute tries to start before libvirt-bin is up it will fail. And
result in the above error.
+
+ [Test Case]
+ * Execute the following commands:
+ sudo apt-get install -y python-software-properties
+ sudo add-apt-repository cloud-archive:grizzly
+ sudo apt-get update
+ sudo apt-get install -y nova-compute
+
+ sudo stop nova-compute
+ sudo stop libvirt-bin
+
+ # simulate that libvirt-bin starts after nova-compute is running
+ sudo start nova-compute
+ sleep 5
+
+ sudo status nova-compute
+ # expected result:
+ # start/running
+ # actual result:
+ # stop/waiting
+
+ [Regression Potential]
+ * This is a modification to the upstart script, and is currently commited in
icehouse.

It looks like there is a race condition between nova-compute-kvm and
libvirt. We should move the init script into nova-compute-kvm and add a
dependency on libvirt. I'll see about updating the package to handle
this
