FYI bug 1788098 was found to be blocked again, but this does not stop
you from prepping the perf-testbed - it only gates the final release of

OTOH there is still some uncertainty which benchmark/setup can be used to do so.
To let us move on with this together I prepared a PPA, on that you can
set up and validate your tests. Please share when you a
Thanks Leonardo!
Since it is a performance fix I'll need your setup (my machines aren't
suited for that) to verify the fix.
Therefore I wanted to ask before the SRU gets started if someone in your Org:
a) are willing and able to do the performance check on the SRU in -proposed then
b) could provi

New Problem, new Bug - at least since the current one is already closed in
Cosmic.
Fortunately the SRU itself was still on hold waiting for another PPC fix to
complete to bundle them so we can make this part of it still.
I forked bug 1788098 for it.
Please set that for reverse bug mirroring to
Thanks Jenifer, the Bionic backport is planned.
FYI on the further timing - Atm I want to push (other) new bits into Cosmic

Then I'll collect libvirt/qemu changes we made in Cosmic and backport all

Part of the 2.12 Test builds at [1] for Cosmic.
It seems good to me, if you can afford a quick test on the ppa feel free to do
so.
Otherwise the final 2.12 upload for Cosmic will be what you could test.

Hi Jennifer,
I'll take a look putting it into the coming qemu 2.12 merge for Cosmic first
(needs to be there for the SRU policy anyway). I saw that it is so new, that is
isn't even in 2.12 (upstream) so I'll add it as a patch to Cosmic as well.
