This should be fixed in 4.4 by recent changes to the QEMU-GA polling mechanism. Can we move it to QE?

Comment 8 Tamir 2020-08-20 08:50:27 UTC

Verified on RHV 4.4.2-3. All looks good to me.


Env:
  - Engine instance with RHV 4.4.2-3 and RHEL 8.2.1 installed.
  - Host with RHV 4.4.2-3 and RHEL 8.2.1, vdsm-4.40.25-1.el8ev, ovirt-engine-4.4.2.2-0.3.el8ev


Steps:

1. Create a 4.4 data center and a 4.4 cluster.
2. Install the host, add a storage domain and create a VM.
3. Run the VM and wait for it's status to change to Up.
4. When it is up, right click -> Power Off.  
5. When it is down, run the VM on the same host.

Results (As Expected):
1. A 4.4 data center and a 4.4 cluster were created.
2. The host installed correctly, the storage domain was created and the VM was created.
3. The VM ran without warnings in the VDSM log.
4. The VM was powered off without warnings in the VDSM log.
5. The VM ran without warnings in the VDSM log.
