Description Gu Nini 2019-10-15 10:44:28 UTC
Description of problem:

This is to track the "Live migration - back/forth between RHEL-ALT 7.6, RHEL-AV 8.1.1 and RHEL-AV 8.2.0 on Power9". Both pre-copy and post-copy live migration need to be tested and supported.

Following test matrix should be run:
    RHEL-ALT 7.6 with qemu-kvm-rhev to/from RHEL-AV 8.2.0
    RHEL-AV 8.1.1 with qemu-kvm-rhev to/from RHEL-AV 8.2.0 

The machine types coverage are: pseries-rhel7.5.0, pseries-rhel7.5.0-sxxm, pseries-rhel7.6.0, pseries-rhel7.6.0-sxxm, pseries-rhel8.0.0, pseries-rhel8.1.0
Please note machine types pseries-rhel8.0.0 and pseries-rhel8.1.0 would only be covered when both src and dst hosts are RHEL8 series.
      
Red Hat Layered Products: RHV and OSP, should review this BZ and specify which versions of RHEL host should be tested. And, prioritize the different combinations based on what customers will be using.

Comment 3 Ademar Reis 2020-02-05 23:07:16 UTC
QEMU has been recently split into sub-components and as a one-time operation to avoid breakage of tools, we are setting the QEMU sub-component of this BZ to "General". Please review and change the sub-component if necessary the next time you review this BZ. Thanks
