I'm using Essex.

Where did you make the code change?

You must put the change on each nova-compute node.

Enable the --verbose flag in nova.conf on your compute nodes,
purge  /var/lib/nova/instances/_base/'ephemeral_something', boot a new vm
and watch the log.
Grep for a line matching 'mkfs'

My logs:

nova.service [-] virt_mkfs : ['default=mkfs.ext4 -L %(fs_label)s -F
%(target)s', 'linux=mkfs.ext3 -L %(fs_label)s -F %(target)s',
'windows=mkfs.ntfs --force --fast --label %(fs_label)s %(target)s'] from
