@exetico tested with virtualbox and it is possible to take a snapshot with VUSB

@exetico I mean when you passthrough a usb, when you want to take a snapshot it gives the error VM_HAS_VUSBS(OpaqueRef:aedd32dc-6dec-4be1-aa5d-9dda799c01b2) and as in version 8.3 you can exclude certain vdi, possibly also a VUSB, that's what I mean

Is it possible to take a snapshot with usb passthrough in version 8.3?

I am playing a bit with SMAPIv3, I created a storage of type file in /mnt/ and a VM, after restarting xcp-ng /mnt/ was not mounted so the storage was not mounted, I did it manually and when starting the VM Throw me

Error code: SR_BACKEND_FAILURE_24
Error parameters: VDIInUse, The VDI is currently in use

I did a detach to the disk from the vm and I also deleted the vm and created a new one but it still gives the same error.

detach and repair does the same

Is there anything new with SMAPIv3?
