[one-users] persistent vm images

[Carlos Martín Sánchez]

Hi Nathan,

You got it almost right, except for

  - set clone=no in the vm template file for the disk
>

The clone, save, readonly, etc. can't be set when your disk is using an
Image [1]. Instead, set your Image as persistent, either at creation with
PERSISTENT=YES [2], or with the 'oneimage persistent' command [3].

Regards,
Carlos.
