oVirt s390x support - some questions for maintainers
by Barak Korren 03 Jan '18

03 Jan '18

Hi to all project maintainers, As you may know, over the last few months the oVirt project had got some code contributions geared towards enabling the use of s390x (Mainframe) machines as hypervisor hosts. As you may also know, if you've followed the relevant thread, some work had been done in collaboration with the Fedora community to enable os390x support in oVirt`s CI system. We're now at the point where we can take the final step and enable automated builds of node components for s390x/fc27. Looking at what we curently build for ppc64le, I already took the time and submitted patches to enable build jobs for vdsm [2], ovirt-host [3], and ioprocess [4]. The relevant maintainers should have had these patches land in thair inbpx already. Few questions remain however: 1. When would be the best time to merge the patches mentioned above? Given that some of the projects do not support fc27 yet, that the new build jobs may raise issues and that the 4.2 release is fast approaching, the right timing should be considered carefully. 2. Which additional projects need to be build? I can see we build some SDK components for ppc64le as wel, are those dependences of vdsm? Will we need to build then for s390x?

Warnings in ovirt-engine build process
by Dominik Holler 03 Jan '18

If a code change adds a warning to ovirt-engine build process, shouldn't CI mark the change as unstable?

[ovirt-users] cloud-init not working on master/4.2?
by Roy Golan 03 Jan '18

03 Jan '18

I had problems bootstrapping my glance images, cloud init seems to ignore my password changes and then I realized I'm missing the cdrom in the domxml. To solve it I disabled the DomainXML feature(engine preparing the domxml, not vdsm) and it started working. Before I open a bug can anyone try to reproduce on 4.2? The workaround with engine-config: echo DomainXML | engine-config -s DomainXML=false --cver=4.2 -p /dev/stdin

WFLYCTL0348: Timeout after [300] seconds waiting for service container stability
by Yedidyah Bar David 02 Jan '18

02 Jan '18

Hi all, Can someone please help debug this failure? It happens to me when deploying hosted-engine --ansible using ovirt-system-tests. So far happened to me once when tried manually and once in jenkins [1] (/var/log/ovirt-engine) [2] (server.log): 2018-01-01 08:19:14,375-05 INFO [org.jboss.as.clustering.infinispan] (ServerService Thread Pool -- 57) WFLYCLINF0002: Started timeout-base cache from ovirt-engine container 2018-01-01 08:23:49,407-05 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0348: Timeout after [300] seconds waiting for service container stability. Operation will roll back. Step that first updated the service container was 'add' at address '[ ("core-service" => "management"), ("management-interface" => "native-interface") ]' On my own system, HE-HA-agent gave up, stopped the machine, started it, and then the engine did start well. In jenkins, we do not give it enough time for this. Now pushed a patch [3] to increase the timeout to 20 minutes (from 10), but this is just to see if it works then. For now, at least. Thanks, [1] http://jenkins.ovirt.org/job/ovirt-system-tests_master_check-patch-el7-x86_… [2] http://jenkins.ovirt.org/job/ovirt-system-tests_master_check-patch-el7-x86_… [3] https://gerrit.ovirt.org/85856 -- Didi
