Description Ilanit Stein 2022-03-10 07:50:11 UTC

The below bug fix will not make it MTV-2.3. Please document this might be the expected behavior.

+++ This bug was initially created as a clone of Bug #2057459 +++

Description of problem:
Warm migration fails on the following error in the case that another snapshot operation (create/delete) is executed on the RHV source VM:

Fault reason is "Operation Failed". Fault detail is "[Cannot create Snapshot. The VM is performing an operation on a Snapshot. Please wait for the operation to finish, and try again.]". HTTP response code is "409". HTTP response message is "409 Conflict".


Version-Release number of selected component (if applicable):
MTV 2.3.0-32 / iib:178080
CNV 4.10.0-686 / iib:178572


How reproducible:
100%


Steps to Reproduce:
1. Start a warm migration plan using RHV VM
2. Create a snapshot on the source VM near the next precopy or the cutover time


Actual results:
Migration fails


Expected results:
MTV should wait for the snapshot operation to finish in order to run the next precopy/cutover
