This is painful bug. We add these lines to nova-compute.conf on each compute node in order to allow migrations:

reserved_host_disk_mb=-2097152
reserved_host_memory_mb=-32768

So we are cheating the scheduler telling them we have -2TB of storage and -32GB of RAM. Then we can migrate more VMs to each node.

It's dangerous if you don't monitor RAM and storage in your compute nodes...

And yes, I can't understand how this bug can still be open after more than 2 years...
