@IBM Am I right assuming that the KVM_CAP_S390_MEM_OP_EXTENSION capability level needs to be set to 211 in 'include/uapi/linux/kvm.h', but also in 'tools/include/uapi/linux/kvm.h'?
(That is at least where I see other settings aligned.)

This file in synced lazily upstream for kernel tools like perf. It does does not hurt to be added there but it is not stricly necessary. So if its in there, fix it up, if its not in there no need to add it.

Thanks for the quick answer.
Ok, so in this case I'll try to keep the patch as small as possible, means only make sure it's properly in include/uapi/linux/kvm.h.

Patch request submitted to kernel team's mailing list:
https://lists.ubuntu.com/archives/kernel-team/2022-March/thread.html#128621
changing status to 'In Progress'.

This bug is awaiting verification that the linux-hwe-5.15/5.15.0-25.25~20.04.1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

This request targets mainly towards 22.04, hence the hwe kernel is more a fall out.
Hence updating tag to unblock the process.

This bug was fixed in the package linux - 5.15.0-25.25
