@julien-f Maybe we do not differentiate "attaching" a disk and "connecting" a disk. I just created a new disk then went to a VM to attach it, then did the same on another VM without problem on XO UI.
BUT it seems that I cannot "connect" it on both VMs, which is not a problem, I only need to know what's possible, and what's not to be able to handle it.
Regards 🙂
