Progress report on Vdsm Debian packaging
by Milan Zamazal
I made progress with Debian packaging of Vdsm. We have all the
supporting packages (cpopen, ioprocess, mom, pthreading, safelease,
sanlock) in Debian now. I took over maintenance of sanlock Debian
package, updated it and made a lot of fixes, including preparing the
previously unavailable python-sanlock package.
As for Vdsm itself, the package can be installed now and Vdsm can be
started. It doesn't work with Engine, which is no big surprise. We
can't simply reinstall a Debian host from Engine, so we need to find
some way how to initialize the host properly. And it's likely there are
distribution specific pieces inside Vdsm and elsewhere.
All the package sources, including not yet uploaded Vdsm package, are
available on http://git.debian.org .
How you can help:
- Obviously, we need to make Vdsm hosts working, so any help in this
area is welcome.
- Reviewing and testing Vdsm Debian package (without actually using it)
is also very helpful, I'm sure there are things to fix or improve.
- There are some Lintian warnings in the packages, fixing them would be
nice.
- We should also review Debian patches in the packages, decide what
should be changed upstream and report it.
- You can help with anything else you consider useful.

Vdsm api package
by Nir Soffer
Hi all,
In the Vdsm call, we discussed a way to expose vdsm errors to its clients
(e.g, engine, hosted engine agent/setup).
The idea is to have a vdsmapi package, holding:
- errors.py - all public errors
- events.py - all events sent by vdsm
- client.py - library for communicating with vdsm
- schema.py - the client will use this to autogenerate online help and
validate messages
- schema.yaml - we probably need several files (gluster, events, etc.)
This will allow other projects talking with vdsm to do:
from vdsmapi import client, errors
...
try:
client.list(vmId="xxxyyy")
except errors.NoSuchVM:
...
(this is a fake example, the real api may be different)
Engine can build-require vdsmapi, and generate java module with the
public errors from
vdsmapi/errors.py module, instead of keeping this hardcoded in engine,
and updating
it every time vdsm adds new public error.
Vdsm will use this package when building response to clients.
Edi was concerned about sharing the errors module, so maybe we need a package:
vdsmapi/
errors/
network.py
virt.py
storage.py
gluster.py
We can still expose all the errors via errors/__init__.py, so clients
do not have to care about
the area of the application the error come from.
Thoughts?

Maintenance Notification: *.ovirt.org Services Today at 18:00 IST (17:00 CET)
by Anton Marchukov
Hello All.
Today at 18:00 IST (17:00 CET) we plan to do hardware upgrades at the
datacenter where most of ovirt.org services are hosted. Although we plan to
minimize the services downtime, it might still be needed.
This does not affect gerrit.ovirt.org but may impact jenkins and other
services.
The maintenance window is scheduled to last for 2 hours.
Anton.

are there any ways to disable the log file?
by zhukaijie
"Since oVirt 3.5.0 (VDSM 4.16.0), VDSM does not enable the overly verbose libvirt debug logs automatically." from http://www.ovirt.org/develop/developer-guide/vdsm/log-files/.
So my problem is.
Each running VM has it's command line logged in /var/log/libvirt/qemu/${vmname}. And now I'd like to disable this log function, that is to say, not to record the QEMU command line of VM. So could oVirt or VDSM disable this qemu command line log file just like libvirt debug logs? Thank you.

I suppose the cpopen parameters are not alright…I’m sure vdsm developers can help with that.

ovirt 3.5 to 3.6 upgrade
by Paul Dyer
Hi,
after upgrade to ovirt 3.6, the ovirt-release35 repo remains on the manager
machine (non-hosted engine). There is also a list of rpms from the 3.5
repo.
Should the 3.5 repo be removed? What about the rpms from the 3.5 repo?
Should they stay or go?
Here is a list of 3.5 repo rpms still installed:
# yum list installed |grep ovirt-3.5
ovirt-engine-jboss-as.x86_64 7.1.1-1.el6 @ovirt-3.5
patternfly1.noarch 1.3.0-1.el6
@ovirt-3.5-patternfly1-noarch-epel
python-daemon.noarch 1.5.2-1.el6 @ovirt-3.5-epel
python-kitchen.noarch 1.1.1-1.el6 @ovirt-3.5-epel
python-lockfile.noarch 0.8-3.el6 @ovirt-3.5-epel
python-ply.noarch 3.4-4.el6 @ovirt-3.5-epel

[vdsm] new internal stable modules + proposal
by Francesco Romani
Hi,
in the last Vdsm developer call we agreed to promote a few modules in the common repository.
The common repository provides the additional guarantees over regular modules in lib/vdsm/
- stable API
- (thus) safe to use across verticals
the planned moves are:
lib/vdsm/schedule.py -> lib/vdsm/common/schedule.py
lib/vdsm/periodic.py -> lib/vdsm/common/periodic.py
lib/vdsm/virt/api.py -> lib/vdsm/common/api.py
Question is if those modules should go under common/ or under another subdirectory, maybe infra?
Lastly, i have a proposal about better handling of those modules.
First, the mere fact a module is placed under lib/vdsm/common provides the extra guarantees I mentioned.
But should we added more annotations?
for example something like
__API__ = {}
near the top of the module
if this attribute exist, then the module is safe to use across verticals, has stable API and so forth
(this is _in addition_ to the common/ package, not as replacement).
Like:
__API__ = {
"introduced-in": "4.14.0",
"deprecated-from": "4.18.0",
"removed-at": "4.20.0",
"contact": "fromani(a)redhat.com"
}
We could refine further this concept if we like it. The idea is to be lightweight as possible while
carrying all the information we need.
Comments welcome as usual
bests,
