Tanner Danzey commented on CLOUDSTACK-6396:
-------------------------------------------
Submitted potential patch, fixes this error for RBD. Not sure if the issue is
still present for CLVM but if it is, this should fix it.

> KVM RBD Volumes shown as OVM, prevents snapshots
> ------------------------------------------------

> Key: CLOUDSTACK-6396
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6396
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: KVM, Management Server, Oracle VM (OVM), UI, Volumes
> Affects Versions: 4.3.0, 4.4.0
> Environment: Ubuntu Server 13.10, Ceph .72, Cloudstack 4.4-git and
> 4.3.0 release tested
> Reporter: Tanner Danzey
> Labels: kvm, ovm, primary, rbd, storage, ui, volumes

> Original Estimate: 72h
> Remaining Estimate: 72h
>
> Volumes are incorrectly identified as OVM volumes when RBD is used (due to
> RBD and KVM using RAW format in the backend & OVM being assigned sole
> responsibility of all RAW volumes on line 1451 of
> server/src/com/cloud/storage/StorageManagerImpl.java) and this prevents
> snapshotting. The current (VERY BAD) fix is to change the return
> "HypervisorType.OVM" under the RAW case to "HypervisorType.KVM". Of course,
> this has ramifications for OVM users. I will be looking at developing an
> actual proper fix for this.
