Public bug reported:

Hi guys,

    While doing some auditing on disk usage, we've noticed that the
backing device for ephemeral disks is created by a slow mkfs.ntfs (when
the ephemeral disk is ntfs), is there any reasons why it's not done
using qcow2?

Also, could we add a quick format option  ?  Not everbody requires the
same level of filesystem security and sometimes, performances prevail on
security (for internal clouds for instance).

Dave
