Thanks Thomas for pointing out the upstream fix.
IBM has opened a bug that I dup this one on.
There not only one but three patches are suggested.
It would be great if you could take a look there as the

I checked with Breno and while nested virtualization is not something
that they encourage use of in a production environment, it is used for
testing purposes. They would like to have this working with Ubuntu and
have stated it only requires a small fix to qemu. If possible, could

FYI, the pa_features[24] setting has been fixed in upstream in a slightly
different way:

Yep, for some reason, the discussion stalled.
Thanks for working on this bug. HTM bits should be cleared on nested virt,

kvm_pr is not "officially/fully/formally" supported for production use,
but this mode is extensively used by OpenStack Continuous Integration
and it is the testing ground for many other projects. This statement of
"not supported" has been changing and Power ecosystem depends on kvm_pr
for platform
I'm not entirely sure if kvm_pr (or more defined "the TM feature inside
kvm_pr") is meant to be fully supported by IBM owning power in general.
Subscribing / pinging them for their expertise on this.

After going the wrong direction for a while I see the almost hidden, yet so
important words - "in nested only" !
That also explains the kvm-pr I wondered about, as I'd have expected kvm-hv if
in 1st level.
I tried as you instructed - on first stage it worked (Host to lvl 1)

Hi,
I mostly run with cloud-images so I haven't seen this yet (I always prefer
uvtool-libvirt to virt-install).
Thank you already for your good summary!

Sounds like your problem only occurs on older versions of Ubuntu, so
moving this to the QEMU-Ubuntu bug tracker.
