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,
