Dear all,

I'm glad to tell everyone that we finally succeeded to build Devstack and
run full tempest tests on it [1].
As the test build result shows [2], the job is stable enough to run.
For earlier 13+ job results. (will do more recheck later)
One Timeout, and two failure cases (Which are targeted by increase
`BUILD_TIMEOUT` to 900 secs).

The job `devstack-platform-arm64` runs around 2.22 hrs to 3.04 hrs, which
is near two times slower than on x86 environment. It's not a solid number
as the performance might change a lot with different cloud environments and
different hardware.

But I think this is a great chance for us to make more improvements. At
least now we have a test job ready (Not merged yet) for you to do
experiments with. And we should also add suggestions to Multi-arch SIG
documentation so once we make improvements, other architecture can share
the efforts too.
*So please join us if you are also interested in help tuning the
performance :)*

*Also, we need to discuss what kind of way we should run this job, should
we separate it into small jobs? Should we run it as a periodic job? voting?*

*On the other hand, I would hope to collect more ideas on how we should
move forward.*
*Please provide your idea for this on our Xena PTG etherpad*


Our PTG is scheduled around 4/20 Tuesday from 07:00-08:00 and 15:00-16:00
(UTC time)
If you plan to join our PTG, feel free to update our PTG etherpad to
suggest other topics.
And our Meeting time is scheduled biweekly on Tuesday (host on demand)
