operation)
To: Maor Lipchuk <mlipchuk(a)redhat.com>
vdsm-devel is long deprecated. Plesae repost to devel@ovirt, and include
alitke, the owner of _manifest on your CC.

Hi,
I've been trying to remove a single snapshot and consistently fail with
the
following error (see [1]).
Those are my steps:
1. Create a VM + Disk
2. Create a snapshot
3. Remove the snapshot
My VDSM is the latest (commit d7796fb8bdd5b424ecad54dc36cb58cd477b3224)
Is there a bug open on it? or even better, fixing patches?
