[one-users] Move an image

[Ruben S. Montero]

No, you cannot yet :( see [1,2].

However you can do the procedure manually. Let's assume that:

a. You already have a new datastore, ready and available
under /var/lib/one/datastores/<ID>
b. There are no VMs running using the images to be moved

Then:

1.- Move the image file to the new place, you can keep the hashed name

mv /var/lib/one/datastores/106/fc0b14ee* /var/lib/one/datastores/<ID>/

2.- Register a new image.You can keep the previous attributes if any (e.g.
DRIVER or CACHE) **but be sure** to include:
     * SOURCE set to point to the new location
     * SIZE set to the original value

This procedure can be easily script'ed if there are too many images.

Cheers

Ruben
