Yourdan, please look at the API [1]. I'm not sure what your hypervisor
supports. This is documented to only work on KVM.
In general I wouldn't concern myself with umount when reverting volume, but 1.
shutdown the VM 2. attach the reverted volume and 3. boot up again.
Hope you're successful with your design,
