[ovirt-system-tests] ssh to an oVirt VM in Lago
by Valentina Makarova 06 Jun '17

06 Jun '17

Hello! Please, help me to find way to execute some command in oVirt VM. Is it possible to get ssh connection to non-host VM in LAGO? And how can I get ssh connection through the console in my computer? I installed ovirt-system-tests and run tests from basic-suite-master. So there is 2 hosts and 3 vms in my configuration. And I want to execute command inside the vm0 using LAGO (as part of my own test). It is easy for host vm and engine, there is method ''ssh" in ovirt-engine-api-model. And this task for host vm can be performed as there prefix.virt_env.get_vm(VM_NAME).ssh(['bash_command_what_i_want']) Please give me advice, can Iget connection to vm0 in a similar way? And a second question is about ssh to this vm connection from my laptop's console. According run_vm test from 004_basic_sanity.py ( https://github.com/oVirt/ovirt-system-tests/blob/master/basic-suite-master/… ) vm0 should contain interface with ip 192.168.200.200, but ping this from engine (192.168.200.4) Destination Host Unreachable. And 'ping vm0' defined vm0 as 192.168.201.213 and also couldn't reach vm0. And in webadmin (https://engine/ovirt-engine/webadmin/#vms) IP Address field is empty. What is a right way to get connection to vm0 console and execute some command there? Sincerely, Valentina Makarova

Fwd: Lago v0.39 is out!
by Nadav Goldin 04 Jun '17

04 Jun '17

---------- Forwarded message ---------- From: Nadav Goldin <ngoldin(a)redhat.com> Date: Sun, Jun 4, 2017 at 2:24 PM Subject: Lago v0.39 is out! To: lago-devel(a)ovirt.org On behalf of the Lago team, I'm pleased to announce the new release of Lago and Lago-ost-plugin: Lago - v0.39 Lago-ost-plugin v0.41 This is the first release where we've separated Lago and lago-ost-plugin(aka ovirtlago) to different repositories, installation procedures should be the same. However, from now on the lago-ost-plugin will follow a different release cycle. It's repository can be found at [1], and docs at [2]. Note that 'lago-ost-plugin' requires Lago >= 0.39. What's new ========= Lago ------- 1. Improved Ansible inventory support. For more details see [3]. 2. Lago SDK - Allows to run most CLI operations directly from Python. See [4] for the docs, and [5] for an example. This is mostly standardization of the already provided SDK. 3. Debian network support in bootstrap stage. Lago Images ----------------- 3 New images were added, please help in verifying them: 1. fc25-base 2. debian8-base 3. ubuntu16.04-base There is a known issue with host name resolution after boot in debian, but it does not affect connectivity. Tests/CI ------------ 1. Moved to tox to setup the virtualenv during the tests: * `tox -e docs` - builds the docs. * `tox -e py27` - run unittests and linters. * `tox -c tox-sdk.ini -- --stage check_patch/check_merged` - to run the functional SDK tests for each stage(after you have installed lago - either in a nested virtualenv or from RPMs). 2. Added SDK functional tests: * Easy to run sanity check while developing, under tests/functional-sdk run: `pytest -s -vvv --setup-show --stage check_patch test_sdk_sanity.py` 3. Added multi-distro tests, which means prior to merging every Lago patch, we'll ensure the core images in templates.ovirt.org are functional with the new patch. 4. Added ansible functional tests on check-merged. For the full changelog see [6]. Upgrading ======== To upgrade using yum or dnf, simply run: ``` yum/dnf update lago ``` Resources ======== Lago Docs: http://lago.readthedocs.io/en/latest/ GitHub: https://github.com/lago-project/lago/ YUM Repository: http://resources.ovirt.org/repos/lago/stable/0.0/rpm/ OST Docs: http://ovirt-system-tests.readthedocs.io/en/latest/ As always, if you find any problems, please open an issue in the GitHub page. Enjoy! Nadav.

Using more specific types in code visible to GWT frontend
by Vojtech Szocs 02 Jun '17

02 Jun '17

Hello, in GWT world, being more specific (e.g. using ArrayList instead of just List) is preferred since the GWT compiler doesn't need to introspect all possible subtypes and include them in the generated JavaScript. Using too "generic" types is one of the main reasons of significant GWT-generated JavaScript size. I'd like to improve this and I'm wondering what others think. For example, in BusinessEntity interface, is there any reason why <T extends Serializable> and not e.g. <T extends Guid> ? If the GWT compiler sees a reference to Serializable type and it isn't obvious what's the instance type behind it, it includes *all* Serializable subtypes into the generated JavaScript. You can probably imagine how many of those are visible to GWT compiler via Java classpath. Another example is query & action result allowing arbitrary List/Map/Set impl. to be passed through GWT RPC. What about limiting us to ArrayList, HashSet and HashMap for GWT RPC transfer? Please be aware that usual Java performance tips do not apply to GWT world due to Java-to-JS compilation. (And therefore, using LinkedList instead of ArrayList has no practical effect aside from bigger JS footprint.) I'd like both frontend and backend maintainers to share their thoughts. Alexander's UI redesign efforts [1] are well on their way into the master branch and it's a good opportunity to improve existing GWT frontend, making it smaller & faster for our users.

Engine query & action result classes are now final
by Vojtech Szocs 02 Jun '17

02 Jun '17

Hi everyone, yesterday, we merged https://gerrit.ovirt.org/#/c/75705/ which seals Engine query & action result classes. We will follow this up with renaming "VdcReturnValueBase" to "ActionReturnValue" and doing similar renames to existing "VdcSomething" classes. The reason for finalizing those result classes is to avoid us implementing a GWT custom field serializer for each such subclass, therefore limiting our exposure to GWT RPC specifics when transferring objects between client and server. On a side note, we also upgraded GWT 2.8.0 to 2.8.1 which fixes a GWT compiler bug we had to work around: https://gerrit.ovirt.org/#/c/77264/ Regards, Vojtech

Hi, I want to fix some issues in ovirt site.

[VDSM] Fedora rawhide build - works!
by Nir Soffer 31 May '17

31 May '17

Hi all, We have now a Fedora rawhide build on travis: https://travis-ci.org/nirs/vdsm/builds/231649060 To make it work, I had to: - disable kvm2ovirt import test, since ovirt-imageio-common is not available for rawhide on ovirt repos Building ovirt-imageio for rawhide should be easy - disable 2 tests importing blivet, since importing it fail with ValueError on rawhide (blivet bug?) The build is using ovirtorg/vdsm-test-fedora-rawhide image. Please review: https://gerrit.ovirt.org/#/q/topic:rawhide Cheers, Nir
