I've got a VM with a pair of snapshots that won't delete and I'm needing a
procedure to manually remove the snapshots. I don't need the VM and so while i'd
prefer not to destroy it, it wouldn't be critical if I did damage the VM in the
process. When I try to delete the snapshots that procedure fails, and when I try to delete
the disk that procedure fails. Any pointers would be greatly appreciated.

Hi,
I think the only way is to clone VM and then destroy old copy, someone from oVirt dev team
please comment.

I just tried that clone method per your suggestion and I got "VDSM command
CopyImageVDS failed: Image is not a legal chain:
(u'6af66318-e6f8-45d7-8b4e-2183faf0a917',)"

Hi,
There is another way to make a clone.
Can you create a new snapshot, and make a new VM based on this snapshot?

Checked my old notes, had to directly alter PostgreSQL db several times,
yet my cases were different.
I think this can be still fixed with editing PostgeSQL database directly.
A blueprint for your solution may be found here, someone from Red Hat
had to clarify:
https://noeschanga.wordpress.com/2018/02/09/how-to-solve-snapshots-state-...
This for example is a fix for unknown VM status.
su - postgres
psql engine
select vm_guid from vm_static where vm_name='MyProblematicVM';
vm_guid
--------------------------------------
b1b8d576-9567-aaaa-yyyyy-xxxxxxx
(1 row)
select status from vm_dynamic where
vm_guid='b1b8d576-9567-aaaa-yyyyy-xxxxxxx';
status
--------
7
(1 row)
update vm_dynamic SET status=0 where
vm_guid='b1b8d576-9567-aaaa-yyyyy-xxxxxxx';
update vm_dynamic SET run_on_vds=null WHERE
vm_guid='b1b8d576-9567-aaaa-yyyyy-xxxxxxx';

This worked for me. I was able to delete the bad snapshot reference and then hose the VM.
Thank you for the help !
