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.
