Okay, bringing the leafs of the discussions onto this thread.

As per

http://www.phoronix.com/scan.php?page=article&item=linux_2631_kvm&num=1&single=1

"The host OS (as well as the guest OS when testing under KVM) was running an Ubuntu 9.10 daily snapshot with the Linux 2.6.31 (final) kernel"

I am attempting to get the actual "daily" snapshot to provide the precise version. I should have that information shortly. It is likely that it was within 1-2 weeks prior to the article posting.

The "probably" was described above - it was a snapshot after the 2.6.31 final as September 9th, the article was published on September 21st, so there is a finite window.

I have high confidence in the testing that Phoronix has done and don't expect to need to confirm the results explicitly,

Your confidence is misplaced apparently.

and I have pieced together the following information. I should be able to get the actual daily build number but broadly it looks like it was

  Ubuntu 9.10 daily snapshot (~ 9th - 21st September)
  Linux 2.6.31 (packaged as 2.6.31-10.30 to 2.6.31-10.32)
  qemu-kvm 0.11 (packaged as 0.11.0~rc2-0ubuntu to 0.11.0~rc2-0ubuntu5

That's extremely unlikely.

But, if it turned out to be Ubuntu 9.10, linux 2.6.31, qemu-kvm 0.11 would there be any concerns?

It's not relevant because it's not qemu-kvm-0.11.
