Hey, did you saw the notice 'data loss warning'?
Sorry, no "how to use these list VM" now.
All I post was just a way to return slaves to pre-installed state to
allow them rejoin pool (new pool).
You can try to scavenge VM data from storage (which should stay intact,
I think) but that require deep digging in VHD, LVM and so on.
Which SM did you use?
