Dear Personnel,

It seems that the OST is failing due to a storage issue [1]. The failure is on the test_verify_and_remove_cloned_vm test which is not changed on the patch [2] .

2020-12-01 13:07:48,297+01 ERROR [org.ovirt.engine.core.bll.storage.domain.AttachStorageDomainToPoolCommand] (default task-1) [] 

An error occurred while fetching unregistered disks from Storage Domain id '26d55c27-bf61-4f01-b5a3-d9a6a01c3e8a'
2020-12-01 13:07:48,298+01 DEBUG [org.ovirt.engine.core.bll.storage.domain.AttachStorageDomainToPoolCommand] (default task-1) [] Skipping format update for domain '26d55c27-bf61-4f01-b5a3-d9a6a01c3e8a' (type 'ImportExport')

and returns the following error:

2020-12-01 13:17:46,784+01 ERROR [org.ovirt.engine.api.restapi.resource.AbstractBackendResource] (default task-2) [] Operation Failed: 

[Cannot remove VM. The VM is performing an operation on a Snapshot. Please wait for the operation to finish, and try again.]

Maybe there is a recent change causing a regression here?
