RH-Commit: [1/1] 1ed82e56fe74a283a1726c4893dc3387e645072c (clegoate/qemu-kvm-c9s)
|
|
|
|
commit c7b14d3af7 ("s390x/s390-virtio-ccw: Switch off zPCI enhancements
|
|
on older machines") activated zPCI enhancement features (interpretation
|
|
and forward assist) silently on the s390-ccw-virtio-rhel8.6.0 machine
|
|
for RHEL8.8. It didn't seem to be a problem since migration is not
|
|
possible but it broke LEAPP upgrade to RHEL9 when the machine is
|
|
defined with a passthrough device. Activate the zPCI features also on
|
|
RHEL9.2 for the machines to be alike in both latest RHEL distros.
|
|
|
|
Upstream Status: RHEL-only
