I have made this change and I'm validating this now in my lab.
> Unable to detach root volume when using Hypervisor Type KVM
> -----------------------------------------------------------
>
> Key: CLOUDSTACK-9349
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9349
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Volumes
> Affects Versions: 4.5.1, 4.6.2, 4.7.1, 4.8.0, 4.9.0
> Environment: Centos 7
> Reporter: Simon Weller
> Priority: Minor
> Fix For: 4.7.2
>
>
> Back in 4.5, support was added in CLOUDSTACK-6284 for detaching root volumes.
> The original support was meant to work with Xen, VMware and KVM.
> After chatting with fuflo in the Cloudstack irc channel, it was pointed out
> that a constraint was not correctly modified in VolumeApiServiceImpl.java to
> allow the detach to occur when vm.getHypervisorType() == HypervisorType.KVM.
> This is a very useful feature, as it allows us to simulate a snapshot revert
> with Ceph by using createVolume sourced from a snapshot, then detaching and
> reattaching the root volume (new root volume needs to be attached as
> device=0).
> I'm going to propose a PR for this shortly
