The big part of this task was indeed to properly complete the modularization of engine setup: now you can run engine-setup only for the websocket-proxy stuff and it don't try anymore to setup jboss AS and DBMS stuff as it did in the past. We need that in any case. The work on the console UI for websocket proxy cert was quite small since the 'interface' is really simple. Of course we can do better, but I'm not so sure we really need it now. Actual solution can be judged cumbersome but I think that only a few sysadmin are really going to install the websocket proxy on a separate host; I'm almost sure that they aren't going to move it one day on an host and one day on another so a bit of manual work on my opinion can be acceptable on that.

Nothing fancy here, just the differences from RHEL6.5 to RHEL7.
See the attached graphs:
* baseline_{cpu,mem}.png is RHEL 6.5
* baseline_{cpu,mem}_7.png is RHEL 7.0
RHEL7 is so *much* better, switching the hypervisor host is by far
the biggest (and easiest) gain we achieved so far.
Are these showing the current vdsm code, before the scalable_sampling
branch?
exactly. Plain vanilla master.
coming soon:
- discussion about the impact of the scalable_sampling topic branch
I want to see the numbers the new graphs
sure, is the very next thing
PS: a couple of updates about specific points (Michal, Nir)
- still no luck with yappi on RHEL7, managed to do the above bench
with 10 VMs and collected a profile.
Can you share the profile with us?
please find attached.
Thanks, looking
- 30751 is a win, same of the last changes of
http://gerrit.ovirt.org/#/c/29980/
(revs 12, 13)
More details?
Yep, let me just re-run benchmarks to highlight the impact changes on
isolation.
After that I'll send a followup mail discussing the impact of
- our new topic branch
- our new topic branch + 30751
on both RHEL 6.5 and 7.0
not sure if it is worth to bench 29980 v13 directly or to have one set for
29980 v11 and one for 29980 v13
I'm sure that you should not waste your time on comparing minor versions
of the patches.
We should focus on comparing master with master + latest scalable_sampling.

I just discussed it with Alon as it involves security concerns. I think we found a good compromise adding also the opportunity to save the CSR into a file still asking to the user to manually transfer and sign it on the other host. I'm going to fix it. ___ Devel mailing list Devel@ovirt.org http://lists.ovirt.org/mailman/listinfo/devel
