Moving back to assigned, as http://gerrit.ovirt.org/35220 broke upgrade from 3.4. see bug 1167769.

To know which version you upgrade from, you can use self.environment[osetupcons.CoreEnv.ORIGINAL_GENERATED_BY_VERSION] - should contain a string, e.g. '3.4.4' or '3.5.0'.

but perhaps better to condition this on existence of the table 'command_entities'.

Indeed, and this is what I plan to do.
Thanks!

oVirt 3.5.1 has been released and since this bug is targeted 3.5.1 and in modified state, it should be included in this release.
Please re-target and move nack to modified if this assumption is not valid for this bug.

*** Bug 1190228 has been marked as a duplicate of this bug. ***

any update on this bug? it's currently failing a ci job:
http://jenkins.ovirt.org/job/ovirt-engine_3.5_upgrade-from-3.4_merged/

this ovirt bug was fixed during 3.5.1 cycle and is included in the build, and therefore should be verified.

I installed version of oVirt: ovirt-engine-3.5.1.1-1.el6.noarch (there isn't patch yet)
I sucessfully added a Host, Storage domain and created 1 VM
After I started making a template from VM, I turned down the network of the Host to create a zombie task.
I removed the host from engine for sure.
Then I want to upgrade the engine to version
ovirt-engine-setup-3.5.2-0.0.master.20150226114525.el6.noarch.rpm (Patched)
but when making the setup of the engine I got error:

We found other issues handling AsyncTaskZombieTaskLifeInMinutes to identify the zombies. Now it should work.

Moving to integration, and assigning to you, Simone.

Oved, can you please exact flow that you want QE to test here?
There is a lot of code changes related to this bug and we do not want to miss regressions on this.

Exactly what Petr already did when he tried to verify it in the past. See Comment 12.

I guess this change goes deeper than just that flow. Please provide list of affected areas to test that changed.

It doesn't go deeper. Petr can contact us if he needs to.

I tried to verificate this bug during the upgrade from latest_av and from vt13.11.
I created a zombie by comment #12 (template). While I did the upgrade of the engine from latest_av to vt14.2:

While I did the upgrade of the engine from vt13.11 to vt14.2, behaviour was a little different:

          (Answering "no" will stop the upgrade (Yes, No)

But, it's a zombie and I have only two options: 
- stop the upgrade
- forever wait

I thing it doesn't recognize that it is a zombie.

latest_av

vt13.11

Please, verify on VT14.2. VT 13.11 is known to be affected.

I tried two upgrade: latest_av >> vt14.2 and vt13.11 >> vt14.2. So moving to ASSIGNED

Verified with template zombie in vt14.2 (rhevm 3.5.1-0.3.el6ev) 

There is the timeout after that the tasks is marked as zombie.
For testing I changed the value of AsyncTaskZombieTaskLifeInMinutes in table vdc_options from 3000 to 30 minutes.

ovirt 3.5.2 was GA'd. closing current release.
