Hello Andreas,
I can't seem to find anything wrong with your setup. I have a question,
though, once you do onevm saveas does it show in "onevm show <vm_id>" like
this?
$ onevm show <vm_id>
[...]
DISK = [
[...]
SAVE="YES",
SAVE_AS="4",
SAVE_AS_SOURCE="/var/lib/one/datastores/1/9e2ca60e8780e40f79d13e7d587b471c",
[...]
cheers,
Jaime
