Description

This issue is to move disk images across system datastores, for VM's in power off state. Initially the issue will require TM's of source and destination be the same.

To implement the original request a manual conversion step will be required and may not work because the VM Template will use specific drivers to access the disks (i.e. raw).

Also once this is ready onedatastore flush will be implemented to move all VMs in a given DS to enter maintenance.

Original description for this issue:

Hello,

I would like to move images between different datastores.

I have a *@default@* datastore with *@TM_MAD=shared@* and I would like to switch it to *@TM_MAD=qcow2@*.

My problem is that *@raw@* images do not work with *@TM_MAD=qcow2@*.

I need to create a new datastore for *@raw@* images and move them in it without changing images IDs.

Regards.

This also refers to the ability to move the images of a VM (poweroff) from a system DS to another one.

looks like interesting feature to migrate vms betwen different storages/datastores and to allow single gold os image to have for vms with different datastores.

it comes to my mind like, there could be some special drivers for every datastore - pipein pipeout .... where you could connect the two drivers of different datastores together. (does it sounds realistic?)

This is in fact very interesting, not sure if as part of this feature, but we are considering a kind of remote datastore, so you can actually transfer images between opennebula zones, or from a marketplace... This is very similar to the pipe's idea you propose.

Unfortunately there is not direct way to do this. Datastores are local to each zone, so you need to export/import the images.
