I'm following this (tutorial) for Ubuntu 12.04. Up until the end of Chapter 7, everything goes smoothly. But when I try to launch an instance with:

nova boot --flavor m1.tiny --image cirros-0.3.2-x86_64 --nic net-id=b8c68b13-2991-45d6-86d9-c980cf2cde5b --security-group default --key-name demo-key demo-instance1

I get the following error from "nova show":

fault | {"message": "No valid host was found. ", "code": 500, "created": "2015-01-08T14:04:22Z"}

Looking at the logs, I found this at /var/log/nova/nova-scheduler.log:

The only solution I found was updating to 14.04. After that, the problem is no longer.
