Hey guys, 


Not sure if this is a bug or something wrong on my end. Attempting to conduct a live migration between two compute nodes I have running. Using Essex release rc1. When I execute the following command: 'nova live-migration <server_id> <compute hostname>' I get an HTTP 400 failure. Below is an error that I found in my nova-scheduler.log file:

I can't seem to figure out what file is is trying to find. Just looking to get some guidance on this.
