[one-users] Persistent VM instance storage?

[Javier Fontan]

Hello,

If the images for persistent storage are located in a shared directory
exported to execution nodes you can simply specify its path and set
CLONE=no in the template file. That way the VM will have access to
that image and could be used after the VM is shutdown for other VM. If
you do not have a shared directory use CLONE=yes and SAVE=yes when
specifying that image so when the VM is shutdown the modified image is
copied back to $ONE_LOCATION/var/<vmid> in the frontend machine.

Bye
