Hi Eric,
Thanks for trying and reporting this. This kunit test depends on
availablility of Qemu commit 5f7d861e("spapr: nested: Add support for
reporting Hostwide state counter ") [1] that was merged in v10.0.0.
Since you havent mentioned the qemu version used I assume its a version
< v10.0.0 . With the qemu patch available you should see this test
passing with results similar to as originally described in original
cover letter of the patch series at [2] that introduced this kunit test.
