Hi, I'd like to discuss what's being tested by oVirt System Test.

I'm investigating on a sanlock issue that affects hosted engine hc suite.
I installed a CentOS minimal VM and set repositories as in http://jenkins.ovirt.org/job/ovirt-system-tests_hc-basic-suite-master/128/artifact/exported-artifacts/reposync-config.repo

Upgrade from CentOS 1708 (7.4) minimal is:

meaning this environement is not receiving updates to core packages like the kernel.

Restricting to libvirt, with the repos used in the job libvirt packages doesn't even exists, making yum install libvirt just fail.

I think you already know I'm against filtering packages from the repos even if I understand it saves a huge amount of space and download time.
I may be wrong, but I tend to not trust OST results since it's not testing real life environments. Any chance we can improve OST to match what users are going to have on their systems?

Specifically for the hosted-engine use case, I had the same suspicion, so I patched Lago to use '--network' in virt-sysprep and added 'update' command to ensure all hosts are fully up-to-date when deployed.
It did not solve the issue.

Generally:
1. Updating the images take quite some time, per run.
2. I agree every X months we should be updating the images. Every Q for example. I've already discussed this with Gal. If CentOS would have released a new baseline, that would have been more real life scenario, btw.
3. That being said, if you need a dependency, you need to depend on it, and we'll pull it. We do not ask (I think?) to 'yum update' your system before deploying oVirt.

Actually yes, we require it. See https://ovirt.org/documentation/install-guide/chap-Installing_oVirt/
It explicitly says to yum update before proceeding with the deployment and reboot the machine if kernel has been updated.

Isn't that just for engine side? do we have the same requirement for hypervisors as well?

Not 100% sure but ovirt-engine in 4.2 should be performing yum update on host upgrade and this obviously don't pull in new packages if they are filtered out at repository level.
Adding Martin to keep me honest on this.

4. There were, luckily, very few o-s-t only issues thus far. It may happen, and we will run into those, but we have not so far encountered many. Some we did not bother pursue, though are clear bugs (I remember an annoying one with 'mount' command not getting back at all, etc.)
Y.
