Heads up: Engine 3.6.5 branching out next week
by Tal Nisan 24 Mar '16

24 Mar '16

Hey everyone, Around mid next week Engine 3.6.5 will be branched out from the ovirt-engine-3.6 branch. This gives the teams a few days of grace to be able to close 3.6.5 issues with a single backport so now will be a good time to go over the patches in the branch and review/verify so they can get merged. Right after the branching out all 3.6.5 patches will have to be backported both to the 3.6 branch and the 3.6.5 branch whereas 3.6.6 patches will be backported to the 3.6 branch only. Another heads up on a related issue: there are currently 38 open patches in the 3.6 branch some of which date as far as January. As this clutters my everyday work on the branch, right after branching out I'm going to clear out stale patches and I'm going to keep abandoning patches in the stable branch that are stale for too long. Bear in mind that in 99.9% of the cases there is no reason for a patch to be open on the stable branch for more that 2 weeks after it's merged on master.

Reviews needed for ovirt-system-tests
by Eyal Edri 24 Mar '16

24 Mar '16

Hi, There has been progress with fixing a few issues on ovirt-system-tests and patches were submitted [1]. We would like to merge them ASAP so the ovirt tests for 3.6 and 4.0 can get one more step closer to working and being stable both for developers and for CI. Can you please review the pending patches so we can merge them TODAY? [1] https://gerrit.ovirt.org/#/c/53534 - needs a review https://gerrit.ovirt.org/#/c/53518/ - +1, probably can be merged. https://gerrit.ovirt.org/#/c/54738/ - +1, can get merged. https://gerrit.ovirt.org/#/c/54721/ - +1, can get merged https://gerrit.ovirt.org/#/c/51566/4 - +1, can get merged https://gerrit.ovirt.org/#/c/52681/ - not sure about this one -- Eyal Edri Associate Manager RHEV DevOps EMEA ENG Virtualization R&D Red Hat Israel phone: +972-9-7692018 irc: eedri (on #tlv #rhev-dev #rhev-integ)

[vdsm][virt] what's new in virt (20151215)
by Francesco Romani 23 Mar '16

23 Mar '16

Hi all, I'm happy to start a weekly summary of what's going on on virt's world (VDSM edition). General topics * I've got some mixed feedback about my Vm-on-a-diet effort. I still believe that fat trimming is a worthwhile goal per se, but I'm willing to adapt the strategy responding to the comments, so we will focus on virt-specific topics. * As consequence of the above, I'm focusing on the last bits of device fixing, which involves - fixing all device to update themselves from libvirt XML after domain boot, instead using all the getUnderyling* methods - switch the devices related code to use Etree instead of minidom. This will involve changes to the domain_descriptor. I estimate this task will still trim ~600 lines out of vm.py, so it still somehow gets some size trimming done, albeit not intensive as planned. This is a complex topic, will post plan and ideas on a separate mail * Finally, some series are still worth pushing forward, see below. Patches in need of attention * topic branches - mpolednik started a much needed cleanup and fixing of fake_qemu and fake_kvm code, with the ultimate goal to move all the remaining bits into the faqemu hook, and to make it useful on ppc64. Lots of refactoring is needed to support this change, and that produced https://gerrit.ovirt.org/#/q/topic:cpuinfo - we want to improve the reporting in case of migratio aborted. The ultimate goal is to let Engine (thus the User) know why a migration failed. To export this information, however, we need some cleanup before. Hence: https://gerrit.ovirt.org/#/q/status:open+project:vdsm+branch:master+topic:m… - last and less urgent: here's some cleanup about existing getUnderlying* methods of Vm class, preparing the last step of the big vmdevices split. I believe this is useful anyway https://gerrit.ovirt.org/#/q/status:open+project:vdsm+branch:master+topic:v… * single patches - https://gerrit.ovirt.org/#/c/46846 this is the first of a series aiming to improve migration support in 4.0. Probably worth merging all together, even though this one seems ready for broader review to me. - https://gerrit.ovirt.org/#/c/49173/ Notified just to raise awareness, still working on ensuring backward compatibility and smooth upgrade - https://gerrit.ovirt.org/#/c/48672 v2v xen support - https://gerrit.ovirt.org/#/c/49951/ OVA support improvements. Worth a look, but note that we are working toward a split of this big patch - https://gerrit.ovirt.org/#/c/49636 V2V refactoring, also almost ready - https://gerrit.ovirt.org/#/c/49570/ still in the context of migration enhancements. We want to throttle incoming migrations, to do so we want to use a sempahore which needs to be held by the creation thread until VM is created. This helper makes this possible, using an uniform interface for both this case and the common, simpler case. That's all for now, as usual, reviews welcome! :) -- Francesco Romani RedHat Engineering Virtualization R & D Phone: 8261328 IRC: fromani

removing old ovirt-engine unit tests jobs
by Eyal Edri 23 Mar '16

23 Mar '16

Hi, I'd like to remove the following jobs from CI [1], since they are not adding any benefit over existing logic provided by the standard ci jobs (i.e checkstyle & unit tests already run there). Pros from removing: --------------------------- - reduce time needed to wait on patch verification - reduce load on jenkins - reduce possibility of false positive errors (since they are not running on mock) - reduce load on jenkins in general & maintainability Possible cons: ------------------ - output on unit tests failure might be not nice as existing jobs, but will still provide the relevant error. there is an open ticket on adding support for UI on STD ci, so it will there in the future. If I won't get any rejections or justified concerns on this thread, I will start with disabling them and if all goes well removing them after 1 week.

Maintenance Notification: gerrit.ovirt.org Upgrade Today at 15:00 IST (14:00 CET) - Tentative Time
by Anton Marchukov 23 Mar '16

23 Mar '16

Hello All. We plan to upgrade gerrit to a new version today starting tentatively at 15:00 IST (14:00 CET). However it might be postponed to a later time if we did not manage to get snapshot by that time. During the upgrade the gerrit will not be available. This should not take longer than few hours and I will keep you updated on the progress. Please note that we plan to upgrade to the latest major version 2.12.2. First of all we hope that stability issues that we face are solved there. Besides that consecutive upgrade was required to be able to use online re-indexing limiting downtime. The version has the following core features: - Significant online edit UI improvements - New change submission workflows: Submit Whole Topic and Submitted Together. - Support for GPG Keys and signed pushes. Please let us know if there is anything critical that is preventing us from this upgrade. You can follow up release notes at [1], [2] and [3].

Access to memory snapshots?
by Matt Mossholder 17 Mar '16

17 Mar '16

Hi everyone! I am working on developing a plugin for the cuckoo sandbox ( http://cuckoosandbox.org) that will allow users to select oVirt as a virtualiztion solution. I have it working, for the most part, but one area where I need some guidance is in retrieving memory images. I know that when you take a snapshot, you can request that the memory be stored as well. My issue is that I don't see a way to retrieve the memory, so that it can be feed into analysis tools like Volatility ( http://www.volatilityfoundation.org/) Does anyone have any pointers for me? Thanks! --Matt
