@Ahadas, thanks for creating this doc bug for us. I'm going to move the text out of the Doc Text field, since you are proposing that we had it as a bug fix/doc update rather than a release note, if I understand correctly?

Comment 2 Arik 2021-03-18 21:22:53 UTC
I don't think that I know the alternatives - having a bug in the a section like "5.1.1. Bug Fix" in the release notes of "5.1. Red Hat Virtualization 4.4 General Availability (ovirt-4.4.1)" is fine

Comment 3 Audrey Spaulding 2021-03-19 12:39:21 UTC
Changed Doc Type from Bug Fix to Release Note.

Hi Arik, please review this doc text: 

Previously, migrations of virtual machines initiated on RHEL/CentOS version 8.2 hosts with TSX enabled, and migrated to hosts running RHEL/CentOS version 8.3 or higher could fail. 
In this release, migrations from RHEL/CentOS 8.2 hosts to newer hosts succeed.

Hi Eli,
As it's going to be in RHV documentation I think we should change RHEL/CentOS to RHEL
Other than that, looks good to me

Hi Arik, do we need to add any note in the documentation that recommends restarting the guest host? 

Is this still relevant, or has the issue with TSX been fixed?

no, with the fix to bz 1939013, it is not needed (to restart the guest) anymore
