ovirt-vdsmfake changes
by Roman Mohr
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

vdsm-cli dependency
by Fabian Deutsch
Hey,
I see that vdsm-cli is installed during the host addition flow.
But why isn't it a dependency if vdsm if it is required?

Request permissions for otopi maintainership
by Yedidyah Bar David
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,

[VDSM] Profiling results - 144 cores, 144 vms
by Nir Soffer
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?
Nir

Partial Python3 support for ovirt-engine-lib
by Rafael Martins
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]).

ovirt-3.6 Iscsi restart ends up on bad storage domains
by David Caro
--NU0Ex4SbNnrxsi6C
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Content-Transfer-Encoding: quoted-printable
Hi!
I'm working on getting the ovirt system tests working for 3.6 with lago, an=
d I
have a setup with one vm for the engine, two for hosts, and two other vms f=
or
storage, one of them is nfs (that works well) and the other is for iscsi.
The issue is with the iscsi one, it's an el7.2 vm, I use this script to set=
it
up:
https://gerrit.ovirt.org/#/c/53534/1/common/deploy-scripts/setup_storage_=
iscsi.sh
That works well, I can add the storage domain, but if I reboot the iscsi vm,
moving the domain into maintenance or not, when I start the vm again and tr=
y to
activate the domain it complains with:
VDSM command failed: Storage domain does not exist: (u'63af2399-f37d-441=
a-ac5d-09b65e64ed89',)
VDSM lago_basic_suite_3_6_host0 command failed: Volume Group does not ex=
ist: (u'vg_uuid: rFDadB-GfrW-hHTw-Y5v5-zkWO-HOuC-Y3HAcV',)
If I remove the domain, and manually add it again, it works well, until the
next restart.
Is there anything I'm not doing ok?
I can provide logs if needed (just did not want to spam the list if it's a
known issue).
