[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

Request permissions for otopi maintainership
by Yedidyah Bar David 19 Feb '16

19 Feb '16

Hi, otopi access lists have as unique member Alon Bar-Lev who recently left the project. Since I work a lot on engine-setup which is based on otopi, I have some good experience with it, and also worked on otopi itself in the past, I'm stepping in, proposing myself as maintainer for that project. Thanks, -- Didi

Changing the name of VDSM in oVirt 4.0.
by Yaniv Dary 02 Feb '16

02 Feb '16

Hi, I wanted to bring this up to get feedback on this proposed change. VDSM doesn't align to other project under the oVirt umbrella like ovirt-engine, ovirt-node, ovirt-guest-agent etc.. I suggest for ease of use and tracking we change the versioning to align to the engine (4.0.0 in oVirt 4.0 GA) to make it easy to know which version was in which release and also change the package naming to something like ovirt-host-manager\ovirt-host-agent. What do you think on this? What do you think the name should be?

Re: [ovirt-devel] Debian porting
by Milan Zamazal 01 Feb '16

01 Feb '16

lucas castro <lucascastroborges(a)gmail.com> writes: > Who is working on ovirt debian porting, I'm working on inclusion of Vdsm into Debian. ovirt-guest-agent is already included in Debian (packaged by another Debian maintainer). I'm not aware about any plans to package Engine for Debian nor I plan to do so. There are also Vdsm Debian packages provided by oVirt at http://resources.ovirt.org/pub/ovirt-3.6/debian/, but I don't recommend using them if you are going to use packages from standard Debian distribution once they are ready. While the packages to be included in Debian started from those provided by oVirt, there are many fixes in them and upgrading from oVirt repository packages to packages from Debian is not supported (may change if there is strong demand for that). So mixing those is likely to cause troubles. As for Vdsm in Debian, I've already uploaded most of the supporting packages (Python libraries, MoM) to Debian unstable. Vdsm itself is in preparation. One blocker is old version of sanlock package in Debian and missing sanlock-python package. I wrote to the Debian package maintainer a few days ago, no response so far. In the meantime, it's possible to use sanlock packages by oVirt from the URL mentioned above. (Please note I can't simply upload Debian package of another maintainer without his consent, so we must be patient.) > And how can I help ? If you'd like to help with Vdsm packaging in Debian, you can do so in any of the following ways: - Providing input on your needs. - Providing feedback on what to do with /rhev/data-center mounts directory in Vdsm. It's FHS incompatible and must be changed for Debian (the current location in the package is /run/vdsm/rhev/data-center). The unpleasant thing is that AFAIK migrations are not possible with current Vdsm across machines with mounts at different locations, so we should be careful. - Testing vdsm* packages once they are ready. They're not yet but once they are, testing them will be very welcome. - Providing feedback on the packaging. The git repository is on Alioth: https://anonscm.debian.org/cgit/collab-maint/vdsm.git/ . BTW, if anybody needs commit access (and doesn't have it) to the repository, tell me. Just please coordinate with me in any case so that we avoid duplicate work or conflicting plans. - The `vdsm*' packages are currently lintian clean, but completely untested, even installation may not work. If you'd like to check the installation and to fix contingent bugs preventing it, it's welcome. You'll also need safelease (https://anonscm.debian.org/cgit/collab-maint/safelease.git/) not yet in Debian but ready to upload, I'll do so soon. - Testing whether all the Vdsm related packages from unstable (python-cpopen, python-threading, ioprocess, safelease, mom, vdsm*) work on Debian 8 (jessie) as well. Ideally, they might work unchanged, but in case they don't we may be considering backporting them. - You can also review patches in debian/patches. Maybe some of the changes should be incorporated upstream, maybe some of them should be improved.

Automation CI for vdsm
by Yaniv Bronheim 31 Jan '16

31 Jan '16

Hi all, We want to run functional tests as part of Vdsm CI for each patch before merge. Therefore we need to declare how to automate this process without overloading our jenkins machines. The functional tests will run using lago (https://github.com/ovirt/lago) - It will initiate multiply vms, install vdsm and manipulate it by nosetests or other procedures such as upgrade, removal and so on. Currently standard CI provides check-patch and check-merged scripts ( http://ovirt-infra-docs.readthedocs.org/en/latest/CI/Build_and_test_standar…) the problem with check-merged is that it will run after merge which doesn't help if something fails. We want to allow developers to trigger the script once reviews and verification are ready (last step before merge). To do so we agreed to add Continues Integration flag for each vdsm patch. Once this flag will be signed with +1 it will trigger Jenkins CI to run the check-merged script (adding new button to gerrit is not an option - you can image that flag as a trigger button), on success Jenkins CI flag will turn to +2. on fail we'll get -1 and once new patchset is ready the developer will remove the +1 and add it back to the Continues Integration flag to re-trigger the job. Please ack the process before we move on with that The patch for those scripts still under review and testing - https://gerrit.ovirt.org/#/c/48268 Thanks -- *Yaniv Bronhaim.*
