I tried creating a new node and restoring a snapshot and here's my results.

Restoring across data centres just hung on the first image creation so I deleted the node after an hour and a bit of waiting for it.

Restoring to the same DC worked but when booting the image had a kernel panic, (there's a ticket raised on that with the details).

Edit:
Oh also on the job queue, the title field isn't long enough to show what's being restored it cuts off half way through ubuntu.
