LGTM, I had a few questions.

Please be aware that the next QEMU cycle will have more machines
to deprecate.

pseries-2.1          pSeries Logical Partition (PAPR compliant) (deprecated)

Thanks, I shall address the review comments in next iteration.

I realized that 2.12 had also been marked as deprecated earlier which I
can include in v3, however would like to understand the rationale behind
choosing the remaining until pseries-6.1 for deprecating in next release
cycle. Please enlighten.

Harsh

While at it, could you please also remove the pseries paragraph in
the 'docs/about/deprecated.rst' file  ?

pseries-6.1 is not for this release.

> Please enlighten.

It's in the docs :

   https://www.qemu.org/docs/master/about/deprecated.html
   
   As a special exception to this general timeframe, rather than have an
   indefinite lifetime, versioned machine types are only intended to be
   supported for a period of 6 years, equivalent to 18 QEMU releases. All
   versioned machine types will be automatically marked deprecated after
   an initial 3 years (9 QEMU releases) has passed, and will then be
   deleted after a further 3 year period has passed. It is recommended
   that a deprecated machine type is only used for incoming migrations
   and restore of saved state, for pre-existing VM deployments. They
   should be scheduled for updating to a newer machine type during an
   appropriate service window. Newly deployed VMs should exclusively use
   a non-deprecated machine type, with use of the most recent version
   highly recommended. Non-versioned machine types follow the general
   feature deprecation policy.

We can remove up to v3.0.0. v3.1.0 could be a candidate too,
I will check.

Thanks,
