XO should delete the backup then.
We are currently completely rewriting the backup code, we'll test more once this is released.
These VDI snapshots are attached to VM snapshots which is normal.
XO keeps at least a snapshot per backup for each VM if:
Unfortunately, XO does not currently provide a way to select disks across multiple VMs to migrate them.
It may be possible in the next major release scheduled for September, but not today.
If you are a paying customer, please open a support ticket and we should be able to help you with that.
It's easier for us and it will be handled much more quickly
XO is currently stuck to Node 8 (https://github.com/vatesfr/xen-orchestra/issues/2862).
We'll work on this as soon as we can.
@honold Indeed, we should probably try to upgrade noVNC in XO, but that may not be easy, I fear the lib (and its packaging) has changed quite a lot since 0.6.1.
Anyway, when you see a bug, the best approach is to create an issue on the bug tracker
It should be possible to do it, not sure how easy it would be, anyway it's not planned for the short term, you should create different job for the moment.
Added in my todolist anyway
