Adding TestOnly as per comment7 and comment8

Comment 10 Antonio Cardace 2023-07-11 12:43:45 UTC
@leidwang any chance you retested this with one of the latest builds?

Comment 15 Kedar Bidarkar 2023-11-08 13:17:10 UTC
Can you plz take a look at this bug and see if there is any issue from the RHEL side?

For some reason we need to use the below workaround to get SVVP Tests to PASS.

Workaround:
1.Disable worker node's iommu
2.Specify the VM's machine type to pc-q35-rhel9.0.0

NOTE:
CNV Windows and RHEL Tests do PASS successfully with pc-q35-rhel9.2.0 as the machine type though.

As Leidong mentioned the issue is not reproducible on RHEL, and so far I believe our devel does not find out any RHEL issue regarding this, but I am adding Marek to keep me honest.

Correct. There were no RHEL issues regarding this.

We have seen such issue in the past:
https://bugzilla.redhat.com/show_bug.cgi?id=1247006
https://bugzilla.redhat.com/show_bug.cgi?id=1421588

What is the system timestamp counter source this setup HPET or hv_time ?
