You need to change the 'local_gb' for the instance_type if you want to
accommodate a larger root disk.

http://padl.lv/851301 has some more information.

Use 'nova-manage' to modify the instance type with the 'instance_type'
sub-command.  I'm pretty sure you can't modify a type other than by
deleting and re-adding.
nova-manage instance_type create --flavor=0 --memory=512 --local_gb=2
--swap=512 --cpu=1 --name "m1.xsmall"
