What should I do to support DPDK in ovirt, any instruction?
by lifuqiong＠sunyainfo.com 17 Feb '20

17 Feb '20

Hi All, I found that there is rarely topics about supporting dpdk in ovirt 4.2 in Internet except https://blogs.ovirt.org/2018/07/upgraded-dpdk-support-in-ovirt/; and I can't get information such as whether or not should I install dpdk or ovn manual? And I will get an error when I execute such cmds: ansible-playbook ovirt.dpdk-setup/tasks/main.yml ansible-playbook oVirt.dpdk-setup I have some experience about ovn and dpdk, but I can't make ovirt supporting dpdk according the instruction in https://blogs.ovirt.org/2018/07/upgraded-dpdk-support-in-ovirt/; Is there anybody helping me? Thank you. Mark

somehow, no permission to run VM
by Fedor Gavrilov 15 Feb '20

15 Feb '20

Hi, Have you ever seen an error like this: 2020-02-15 20:05:16,246+01 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ForkJoinPool-1-worker-27) [] EVENT_ID: VM_DOWN_ERROR(119), VM vm0 is down with error. Exit message: internal error: child reported (status=125): unable to open /rhev/data-center/mnt/banana:_nfsshare/45e51eaa-b608-40b1-9db6-6e6a1b3ed428/images/9d440b9a-b033-4209-898b-6667a4605281/ead2017a-a7fe-4408-b8d4-1670cb767474: Permission denied. in the engine logs? I'm getting it on my env (master branch) and can't figure out why. I login as admin, I have a perfectly working host and storage machines, on which I created this VM and its disk. Without any actions in between, I try to run it and get this. Storage domain and data center statuses are updated as you expect when you put the host to maintenance and back, so it seems this is the only thing wrong. Do you know what that might be? Thanks, Fedor

by scott.fitzgerald＠oracle.com 13 Feb '20

13 Feb '20

Hi, A VM Snapshot can be made using SnapshotBuilder builder = new SnapshotBuilder().vm(VM).name("Snap1").description("Test"); sysService.vmsService().vmService(VM.id()).snapshotsService().add().snapshot(builder).send(); It can be made with no memory by using a builder with persistMemorystate(false) How can one be made with no disk? .diskAttachments(emptyList) isnt working. TIA

please stop merging
by Dafna Ron 13 Feb '20

13 Feb '20

Hi all, Engine has been failing for a while and someone has also moved the broken package manually to the tested repo which broke all projects in cq. At this time, until we stabilise engine and get a new package into tested, all projects will continue failing cq and no new packages will be moved to the stable repo (tested). if you continue to merge, we not only risk adding more regression but it also makes it more difficult to debug and fix as there are a lot of changes in the queue waiting to be tested and very little resources to run it. Please stop merging on all projects until this is resolved. Thanks, Dafna

master CQ fails due to missing ovirt-host-deploy
by Dusan Fodor 13 Feb '20

13 Feb '20

Hello, master CQ is failing on initialize_engine due to missing ovirt-host-deploy dependency. [ INFO ] Checking for an update for Setup... [ ERROR ] Yum Cannot queue package ovirt-host-deploy: Package ovirt-host-deploy cannot be found I was under the impression that engine-setup should not require it anymore, but it seems the related patch [1] doesn't work as intended. Perhaps Marcin's comment there explains why? Can you please check this? Job example [2] Thanks [1] https://gerrit.ovirt.org/#/c/106797/ [2] https://jenkins.ovirt.org/view/Change%20queue%20jobs/job/ovirt-master_chang…

Is "Copy Role" functionality possible through the SDK?
by conor.o.o.brien＠oracle.com 11 Feb '20

11 Feb '20

Hi, Is there ability to copy an existing system role via the SDK similar to what's available in the oVirt Admin Portal? I can see add(), update() and remove() but nothing so far that looks like it maps to copy(). Thanks a lot, Conor
