Public bug reported:
I have a nova-compute/libvirt/xen environment (which is not working
properly yet due to another bug I reported here:
https://bugs.launchpad.net/nova/+bug/1190262) and after each reboot
nova-compute is not starting. The log shows that it tries to connect to
localhost:8000 but it fails. Obviously Xen hasn't come up yet before
nova.
