Memory stats in VDSM
by Tomáš Golembiovský 28 Aug '17

28 Aug '17

Hi, there is ongoing effort to change how VDSM collects information about memory usage from guests. We used to use oVirt guest agent to get the statistics about free memory, swap usage, etc. This is going to change and we will use stats provided by VirtIO Balloon driver. [1] This should not break MOM nor Engine (current or previous versions). There is however small downside to this change. We will not be able to fetch information about buffers and caches on Linux guests anymore (mem_cached and mem_buffers in memoryStats). The corollary of this is that free memory reported by Engine will also no longer include those statistics and reported free memory will be really (only) free memory. I now there will be mixed feelings about this and we would like to get the information about buffers and caches back to the VDSM. Correctly via balloon driver statistics. [2] This effort will however take some time.

[oVirt-engine-SDK][Go SDK]
by Joey Ma 28 Aug '17

28 Aug '17

Hi all, I've made a Go sdk for oVirt-engine v4.0+ implemented. The Go sdk generator locates (mainly Java) in imjoey/ovirt-engine-sdk-go of github, while for the Go sdk itself is in imjoey/go-ovirt. With the help of some dear oVirt sdk maintainers, the project has achieved nearly 90 percent now. It is used in production on my job. Meanwhile It's still under active development and the APIs are not stable currently. If it's useful for you, I'm very appreciated for your feedbacks. The project is still on the way, so welcome to contribute, both issues and PRs. That is my pleasure. Glad to meet you all. Best regards, Joey Ma

ovirt-provider-ovn_master_build-artifacts-el7-x86_64 Failing Due to Spec Problem
by Anton Marchukov 28 Aug '17

28 Aug '17

Hello All. Just noted that change queue job [1] for ovirt-provider-ovn started to fail consistently while the actual reason for that seems to be RPM build failure at [2]: *14:47:42* Checking for unpackaged file(s): /usr/lib/rpm/check-files /home/jenkins/workspace/ovirt-provider-ovn_master_build-artifacts-el7-x86_64/ovirt-provider-ovn/rpmbuild/BUILDROOT/ovirt-provider-ovn-1.1-2.20170824144740.gitcf66669.el7.centos.x86_64*14:47:42* error: Installed (but unpackaged) file(s) found:*14:47:42* /usr/share/doc/ovirt-provider-ovn/README.adoc*14:47:42* *14:47:42* *14:47:42* RPM build errors:*14:47:42* Installed (but unpackaged) file(s) found:*14:47:42* /usr/share/doc/ovirt-provider-ovn/README.adoc*14:47:42* make: *** [rpm] Error 1*14:47:42* Took 2 seconds Possible root cause for that is [3] (Install README).

api.vms.get(VM0_NAME).snapshots.list() returned 404
by Yedidyah Bar David 24 Aug '17

24 Aug '17

Hi all, A jenkins job that ran as a check-patch for ovirt-system-tests failed [1] for me due to what seems to me like unrelated reason. It seems to have failed in [2]. This code does various actions with vm snapshots. At some point it failed with 'status: 404' [3]. httpd's log also shows 404 [4] in the end, after a long list of successful actions with snapshots. engine.log [5] shows no relevant error AFAIU. Is this reasonable? Expected? Not sure where the bug is, if at all. Best, [1] http://jenkins.ovirt.org/job/ovirt-system-tests_master_check-patch-el7-x86_… [2] https://gerrit.ovirt.org/gitweb?p=ovirt-system-tests.git;a=blob;f=image-ng-… [3] http://jenkins.ovirt.org/job/ovirt-system-tests_master_check-patch-el7-x86_… [4] http://jenkins.ovirt.org/job/ovirt-system-tests_master_check-patch-el7-x86_… [5] http://jenkins.ovirt.org/job/ovirt-system-tests_master_check-patch-el7-x86_… -- Didi

Lago and vm templates
by Marc Young 24 Aug '17

24 Aug '17

Im currently neck deep in ovirt-system-tests and lago I see alot of usages about importing VMs from templates, but are there any examples of exporting a VM to template? Side note I cant find a good source of methods available for use in python-lago-ovirt (or even python-lago). The docs[1] are pretty lacking [1] http://lago.readthedocs.io/en/latest/lago.html

Host firewalld support patches merged
by Martin Perina 23 Aug '17

23 Aug '17

Hi, we have just merged patches [1], which adds the ability to use firewalld instead of iptables on oVirt hosts. The type of firewall can be defined per cluster, there is new combo box 'Firewall Type' in 'Cluster Detail' dialog. By default all new clusters will be created with firewalld enabled, existing clusters needs to be switched from iptables to firewalld manually and then invoke Reinstall on all hosts in a cluster. Be aware that firewalld can be enabled only for hosts with 4.2 capabilities (VDSM >= 4.20.0). Firewalld deployment is using Ansible role introduced in new ovirt-ansible-roles package [2], which executes ovirt-host-deploy role [3]. ovirt-ansible-roles package is installed automatically if engine is installed from RPM, but for development environment installation please take a look at [4], because ovirt-ansible-roles needs to be installed manually into development environment prefix. Please let me or Ondra know if you find any issues. Thanks Martin [1] https://gerrit.ovirt.org/78504 [2] https://github.com/ovirt/ovirt-ansible [3] https://github.com/oVirt/ovirt-ansible/blob/master/roles/ovirt-host-deploy/… [4] https://github.com/oVirt/ovirt-engine/blob/master/README.adoc#host-deploy-v…
