I'm not sure I understand which RHEV version you're using now.
If you're using RHEV 3.5, it is possible to remove a snapshot of a single disk.
You can do it via webadmin, Under the 'Disks Snapshots' subtab of the relevant
storage domain, in the 'Storage' main tab.
As for your second question, the free space has to be in the same storage domain.

domain?
Hi,
Thats unfortunate :-(. It would have been great if oVirt told me during
the creation of the snapshot that I would be unable to remove it later
due to unsufficient free space in the storage domain :-).
The VM has two disks - a small and a large one - so the snapshot
contains both. Can I still remove the large disk while it has snapshots?
Luckily the used disk space in the (preallocated) large disk is low
enough so I can fit it on another temporary disk then.
Does the free space have to be in the same storage domain, or can oVirt
use another storage domain for the temporary volume? IOW, can I add an
NFS storage domain which oVirt can use to create the temporary disk on?
Regards,
Rik

Snapshot removal (merge) includes a create volume phase. This volume is
temporary and gets removed once the snapshot merge is completed. Its
size is the size of the disk.
That means that in order to remove the snapshot, the storage domain
should have available size that is equal to the disk size.

Hi,
I'm running the ovirt engine 3.4 series. I've created a snapshot of a VM
with an OS and data disk before upgrading the machine.
The upgrade went fine and I now want to remove the snapshot.
Unfortunately this fails with the error:
"Cannot remove Snapshot. Low disk space on target Storage Domain
stadius-virt2_PERC."
So I can't free disk space by removing the snapshot because I don't have
enough space?
When I look at the VM the disks are shown as preallocated (which is what
I selected during installation). When I look at the storage tab and list
the disks in my storage domain, the disks are now shown as thin
provisioned with the actual size > virtual size.
How can I remove this snapshot? I don't have enough free disk space in
my storage domain to duplicate the data disk of my VM.
Regards,
Rik
