Description Miroslav Rezanina 2023-03-22 11:06:15 UTC
With rebase to QEMU 8.0.0 we have to update compatibility bits for qemu-kvm package so we keep old machine types stable.

Please add necessary changes to ensure all machine types are compatible with previous versions.

Comment 6 Thomas Huth 2023-04-17 10:47:24 UTC
I double checked, and this time we indeed do not need any additional compat handling beside the generic hw_compat stuff (which has already been done via hw_compat_rhel_9_2).

Upstream did not add anything beside hw_compat_7_2:
https://gitlab.com/qemu-project/qemu/-/blob/v8.0.0-rc4/hw/s390x/s390-virtio-ccw.c#L838

I think we can close this ticket.
