OVN provider's firewalld services deployment during engine setup
by Leon Goldberg 19 Sep '17

19 Sep '17

Hey, We're trying to come up with a way to deploy OVN provider's firewalld services during engine setup. The naive solution of querying the user during customization and then installing during STAGE_PACKAGES fails as firewalld configuration happens prior to it. We thought of a couple of possible solutions we'd like your opinions on (ordered in perceived level of difficulty): 1) Ship/require the packages with ovirt-engine without requiring user input. This essentially couples engine with OVN and disregards a future where OVN doesn't run alongside Engine. 2) Install the packages immediately following user input during customization. A bit hacky and doesn't conceptually fit the stage of customization. 3) Move user input to STAGE_INTERNAL_PACKAGES. Feels more disruptive than #1 to the current otopi flow as STAGE_INTERNAL_PACKAGES is dedicated for packages that are required for otopi itself to operate. Not only this doesn't fit conceptually, it introduces user input to a stage that shouldn't have any. 4) Move firewalld configuration to happen after STAGE_PACKAGES. 5) Refactor to prepare the grounds for OVN/Engine separation. At this point this feels very ambiguous. We don't yet know how will containers be accessed (is ssh guaranteed?) in the future or generally how should a remote installation look like. Any input/questions are appreciated. Thanks, Leon

New design for the Gerrit UI
by Evgheni Dereveanchin 06 Sep '17

06 Sep '17

Hi everyone, The Infra team is working on customizing the look of Gerrit to make it fit better with other oVirt services. I want to share the result of this effort. Hopefully we can gather some feedback before applying the design to oVirt's instance of Gerrit. Please visit the Staging instance to check it out: https://gerrit-staging.phx.ovirt.org/ The new design is inspired by oVirt's main website. There is a known glitch that the "Loading Gerrit Code Review" message is overlapped by the logo when the UI is loading. If you spot any other issues or have ideas for improvement feel free to respond to this thread or share your feedback in the following JIRA ticket: https://ovirt-jira.atlassian.net/browse/OVIRT-912 -- Regards, Evgheni Dereveanchin

Quartz -> ManagedScheduledExecutorService
by Ravi Shankar Nori 27 Jul '17

27 Jul '17

Hi, We have been working on Threading related changes on engine to move from java ExecutorServices to JBoss ManagedExecutorServices. The dependency on quartz for running scheduled jobs is being phased out and we are moving to scheduling jobs using JBoss ManagedScheduledExecutorService. As far as development goes it should be pretty straight forward. Inject the JBoss ManagedScheduledExecutorService @Inject @ThreadPools(ThreadPools.ThreadPoolType.EngineScheduledThreadPool) private ManagedScheduledExecutorService executorService; and then in PostConstruct you can schedule the job on the executor service using a cron expression. @PostConstruct private void init() { executor.schedule(this::cleanup, new EngineCronTrigger(cronExpression)); } To schedule a job to execute at regular intervals you can use the scheduleWithFixedDelay @PostConstruct private void init() { scheduledExecutorService.scheduleWithFixedDelay(this::cleanExpiredUsersSessions, 1, 1, TimeUnit.MINUTES); } If you have any questions please feel free to contact me or Martin Perina ( mperina(a)redhat.com) Thanks Ravi
