Hi!

I'm running a nova cloud (essex) with both linux and windows
instances. I want the windows images to boot with an ephemeral
pre-formatted ntfs drive.

I've tried setting:
virt_mkfs="windows=mkfs.ntfs --force --fast --label %(fs_label)s %(target)s"

in nova.conf and I've also set the os_type metadata on the windows
image, but nova still uses ext4:

Cheers,
