Multiple NICs on hosted engine, oVirt 4.3
by Jiří Sléžka 05 Apr '20

05 Apr '20

Hello, I would like to add second NIC to hosted engine vm (I need access to isolated network with host's power management). I found this solution... https://lists.ovirt.org/pipermail/users/2014-November/062610.html ...which seems to work in oVirt 3.5 but in oVirt 4.3 there is no file like /etc/ovirt-hosted-engine/vm.conf anymore. In the file /etc/ovirt-hosted-engine/hosted-engine.conf is a line ... conf=/var/run/ovirt-hosted-engine-ha/vm.conf ... which points to this config but this is a running config... Is there a way to add a second NIC to hosted engin vm? Cheers, Jiri

VM and cgroup
by yam yam 04 Apr '20

Hello, I'm wondering why the cgroup for the VM is generated, because I thought VM and cgroup are not related. does qemu/KVM use (memory) cgroup to handle memory resources or something else?

manual migration
by eevans＠digitaldatatechs.com 04 Apr '20

04 Apr '20

FYI: My issue with the inability to migrate is solved. The issue was the ovirt-engine-ui-extensions-1.0.10-1.el7.noarch updated to 1.0.13 and it killed the ability to migrate. In order to downgrade I had to download the rpm, ovirt-engine-ui-extensions-1.0.10-1.el7.noarch.rpm and run a yum downgrade command “yum downgrade ovirt-engine-ui-extensions-1.0.10-1.el7.noarch.rpm”. It would not downgrade any other way. Once it downgraded, migration ability was back. Thanks all for the help and support.

Martin Necas reached out to me and we collaborated on some great improvements. Namely, it is now possible to run the playbook from any host without requiring direct access to storage (which I was previously using for export status verification). There were several other improvements and cleanups made as well. The changes have been merged in and the READMME updated, you can find the project here: https://github.com/silverorange/ovirt_ansible_backup Big thanks to Martin for helping out.

NFS permissions error on ISODomain file with correct permissions
by Shareef Jalloq 03 Apr '20

03 Apr '20

Hi, I asked this question in another thread but it seems to have been lost in the noise so I'm reposting with a more descriptive subject. I'm trying to start a Windows VM and use the virtio-win VFD floppy to get the drivers but the VM startup fails due to a permissions issue detailed below. The permissions look fine to me so why can't the VFD be read? Shareef. I found a permissions issue in the engine.log: 2020-03-25 21:28:41,662Z ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ForkJoinPool-1-worker-14) [] EVENT_ID: VM_DOWN_ERROR(119), VM win-2019 is down with error.

I can't seem to do anything. If I hit the Windows key and start typing, I get a black popup with no options. Win+R doesn't do anything aside from spit out a GSpice critical error in the terminal I'm running remote-viewer from.

New Issue - Ovirt Status shows '?' or Down for all elements
by Mark Steele 02 Apr '20

02 Apr '20

Yesterday we had a storage crash that caused our hosted engine to stop and not auto-restart. We manually restarted it and this morning, all elements are showing a status of either question mark '?' or a red down chevron. We are running version oVirt Engine Version: 3.5.0.1-1.el6. We are chasing it down and see this in the log: 2020-04-01 10:15:53,060 WARN [org.ovirt.engine.core.vdsbroker.VdsManager] (DefaultQuartzScheduler_Worker-23) Failed to refresh VDS , vds = e98f8f1d-dd1d-47c4-b039-d6eaaf578317 : hv-06, VDS Network Error, continuing Any insight into what might be causing this or the fix would be appreciated. *** *Mark Steele*

Ok. Personally, I like having an ISO repository, but I like the fact that's it will be optional. Thanks.

Hosted Engine stalled and unable to restart
by Mark Steele 01 Apr '20

01 Apr '20

Hello, We are on an older version (3.x - cannot be specific as I cannot get my ovirt hosted engine up). We experienced a storage failure earlier this evening - the hosted engine was originally installed with this storage domain although we have moved all VM's and disks off of it. The storage was restored and all the VM's are now running, but the ovirt engine is not pinging and is unreachable. I have attempted to locate it on my HV's using 'virsh list --all' but only one of those is taking my credentials - all the others fail to authenticate. Is there a way to locate what the credentials are on each HV since the default is not working? Additionally, is there any other way to locate the hosted engine and restart it directly from a HV? Thank you for your time and consideration. *** *Mark Steele*
