Hi John, Many thanks for your help. Why don't we allow to set allowed-operations to RW mode in vdi so that I can define the operation myself in creating vdi? [root@xcp1 ~]# xe vdi-param-list allowed-operations (SRO): clone; snapshot

Hi Ray, There's no automated way of reverting a single disk - you'll have to go through these steps: - Shut down the VM - clone the snapshot you want to revert to (xe vdi-clone) - note the userdevice of the VBD connecting the VM to its disk, then destroy the VBD - create a VBD (with the same device number as the VBD you just destroyed) connecting the VM to the cloned snapshot - (optionally) delete the disk you just disconnected from the VM John
