[ovirt-devel] Wrong pep8 library on centos

[Petr Kotas]

Hi,

Sending this to spread information.

I have encountered and issue with Centos 7.4.1708 (Core) when compiling the
oVirt engine.
The pep8 validation was not passing correctly.

It turned out, that the Centos has the old and bugged version present by
default.

The solution is to use the same version as used in oVirt CI.

Just add http://resources.ovirt.org/repos/ci-tools/el7/ to yum.repos.d and
it will start
passing again.


Best,
Petr

[Petr Kotas]

Hi everyone,

first of all, thanks for having an interest in my dev setup :).

Second, I am open to making it more official.

The first step is to create list of missing features.
Please if you can, take a look at the setup and create an issue for any
feature you would like to see in there.

Thanks!!

Best,
Petr

Hi,

you can take a look at my env here
https://github.com/petrkotas/ovirt-dev-env

it is not complete and there is still some work left.

Feel free to contact me if you have any questions.

[ovirt-devel] Failing tests for storage-py27.

[Petr Kotas]

Hi,

I have encountered an issue with VDSM master when running tests.
Maybe I am doing something wrong, or I am overlooking something.

This is a clear master without any modification pulled with the latest
commits.
Did anyone please encountered the same issue:

Re: [ovirt-devel] Question about general testing

[Petr Kotas]

Hi Marc,

I have been working on a development environment for the oVirt. The
environment is basically two VMs running beside together. One runs the
engine, second is a host that runs the vdsm with nested virtualization.
 I am now working on the vagrant file with orchestration to make the
environment setup easier. So if You would wait for a few more days, You
will be able to start from my setup.

As for the containers. For you to have a full test setup, you would need to
place a VM inside the container and run a nested virtualization inside.
This is what the two projects you mentioned are doing. Therefore they are
not that lightweight as you would like.

I would recommend using the VM environment, which is the simplest solution.

I will send a reply again once my environment is up.

Petr

[ovirt-devel] Help understanding the conflict with libvirt-guests.service - gerrit patch 78693

[Petr Kotas]

Hi,

I am kindly asking for help with understanding the origin of conflict
within the *libvirt-guests*.service and *vdsmd.service*.

Explanation:

I am working on a graceful VM shutdown as described by the feature in a
Bugzilla https://bugzilla.redhat.com/show_bug.cgi?id=1334982.

One way (the simplest one as described in the Bugzilla) of achieving the
required functionality is to utilize *"libvirt-guests.service"*, which does
exactly what is required. The second option is to write a new service that
does the shutdown and utilizes the *vdsm.* Since I am new, I do not know
what is the best solution.

Staying with the fist one I have discovered an old conflict between
*"vdsmd.service"
*and *"libvirt-guests.service"* explained in bug
https://bugzilla.redhat.com/show_bug.cgi?id=720359.
<https://bugzilla.redhat.com/show_bug.cgi?id=720359> I have tried to
reproduce described scenario and found that it is no longer an issue.
Therefore I have created a *proposal draft* patch to start a discussion,
whether it is really needed or not.

Further, the research in git history showed this conflict precedes the git
history, effectively blocking me in understanding details.

Does somebody know about this issue? I am grateful for any information that
can point me in the right direction.

Thank you in advance for any help.

Kind regards,
Petr Kotas
