ovirt-vdsmfake changes
by Roman Mohr 22 Feb '16

22 Feb '16

Hi, A small heads up regarding to ovirt-vdsmfake. We merged some changes today which add support for oVirt 4.0 and make it much easier to get started with vdsmfake. With the changes, now it is enough to just run `mvn jetty:run` to have a working vdsmfake. Have a look at the new quickstart guide in the README.md [1] to see how to get started.. Best regards, Roman [1] https://github.com/oVirt/ovirt-vdsmfake

Request permissions for otopi maintainership
by Yedidyah Bar David 19 Feb '16

19 Feb '16

Hi, otopi access lists have as unique member Alon Bar-Lev who recently left the project. Since I work a lot on engine-setup which is based on otopi, I have some good experience with it, and also worked on otopi itself in the past, I'm stepping in, proposing myself as maintainer for that project. Thanks, -- Didi

[VDSM] Profiling results - 144 cores, 144 vms
by Nir Soffer 18 Feb '16

18 Feb '16

Hi all, I noticed that Eldad posted profiling result from 144 cores / 144 vms run: See https://bugzilla.redhat.com/attachment.cgi?id=1128028 Looking at the profile bellow: 1. Why _rtnl_link_alloc_cache is so expensive? called only 389 times, but the most expensive call 2. Creating DomainDescriptor seems expensive - is this xml.minidom? 3. guestagent.py:84(filt) is very expensive - we probbaly want to backport 7091bde guestagent: Speed up xml character filtering, can shave about 17% of cpu time in this run. 4. pthread.py function will disapper from the profile if we replace pthreading with cthreading: https://github.com/nirs/cthreading 5. Why do we see xmlrpc at the top of the profile? Is this the cost of mom calls? Eldad, can you repeat the same test with current master?

Partial Python3 support for ovirt-engine-lib
by Rafael Martins 18 Feb '16

18 Feb '16

Hi, I recently started adding Python3 support to some ovirt Python packages, mainly to fix bug 1254654 [1]. ovirt-engine-lib package now installs files into Python3 site-packages directory. Please note that not all of the features available in Python2 are already available in Python3, because some modules depends on Python2-only stuff, but current changes are enough to fix the previously mentioned bug. Next step is to split ovirt-engine-lib into separated packages for Python2 and Python3, and port code to implement full Python3 support (bug 1306659 [2]). [1] https://bugzilla.redhat.com/show_bug.cgi?id=1254654 [2] https://bugzilla.redhat.com/show_bug.cgi?id=1306659 Thanks, Rafael Martins
