Re: Multiple NICs on hosted engine, oVirt 4.3

Hello Paul, thanks for reply and for pointing me to RHV documentation. Shame on me, I forogot it exists and is well maintained and super relevant for oVirt. But in this case I am a bit lost. I can't find something relevant to my effort to modify HE vm's config to add the second NIC to it. Or do you mean I should change the location of vm.conf from /var/run location to something persistent and then modify this vm.conf as mentioned in that old post? For example, now I got this output for conf key [root@ovirt-hci01 ~]# hosted-engine --get-shared-config conf --type=he_shared conf : /var/run/ovirt-hosted-engine-ha/vm.conf, type : he_shared [root@ovirt-hci01 ~]# hosted-engine --get-shared-config conf --type=he_local conf : /var/run/ovirt-hosted-engine-ha/vm.conf, type : he_local Is it valid to change it to (for example) /etc/ovirt-hosted-engine/vm.conf and modify that file there? Is it safe for further updates, maintenance, etc.? Maybe the second question - which process creates vm.conf in /var/run path?

Re: oVirt Storage quota problems
by Vrgotic, Marko 06 Apr '20

Dear oVirt, Is there anyone willing and able to assist me in troubleshooting what seems to be multiple issues regarding quotas: 1. UI Exception each time I add Consumer to Quota. 2. User getting warning of not being authorized to ‘ConsumeQuota’ in order to AddVM or AddVMFromTemplate, even though User is in Consumers list. 3. Fishy quota usage percentage. I see this strange behavior on all my platforms, so it’s starting to look as a bug to me. Happy to provide any relevant logs or do tests needed. Kindly awaiting your reply. ----- kind regards/met vriendelijke groeten Marko Vrgotic ActiveVideo From: "Staniforth, Paul" <P.Staniforth(a)leedsbeckett.ac.uk> Date: Friday, 13 March 2020 at 18:19 To: "Vrgotic, Marko" <M.Vrgotic(a)activevideo.com>, "users(a)ovirt.org" <users(a)ovirt.org> Cc: Darko Stojchev <D.Stojchev(a)activevideo.com> Subject: Re: oVirt Storage quota problems Sorry haven't used quota in a while, one thought is there a template quota getting used?

power_saving schedule not powering off hosts
by Maton, Brett 05 Apr '20

05 Apr '20

I've got a cluster made up of five physical hosts, (Dells with idrac 7 management) Power management / fencing enabled on all hosts. I've enabled the power_saving scheduling policy on my cluster, it's migrated all the VM's to a couple of physical hosts so three are sitting idle with no VM's. Shouldn't the power_saving policy shut down the idle hosts?

Hello, everyone! I need specialist help, because I'm already desperate. My company has four hosts that are connected to the vault. Each host has its own IP to access the storage, which means host 1 has an ip 10.42.0.10 and 10.42.1.10 -> host 2 has an ip 10.42.0.20 and 10.42.0.20 respectively. Host 1 cannot ping the address 10.42.0.20. Hardware I tried to explain in more detail. Host 1 has ovirt node 4.3.9 installed and hosted-engine deployed. When trying to add host 2 to a cluster it is installed, but not activated. There is an error in ovirt manager - "Host host2 cannot access the Storage Domain(s) <UNKNOWN>" and host 2 goes to "Not operational" status. On host 2, it writes "connect to 10.42.1.10:3260 failed (No route to host)" in the logs and repeats indefinitely. I manually connected host 2 to the storage using iscsiadm to ip 10.42.0.20. But the error is not missing(. At the same time, when the host tries to activate it, I can run virtual machines on it until the host shows an error message. VMs that have been run on host 2 continue to run even when the host has "Not operational" status. I assume that when adding host 2 to a cluster, ovirt tries to connect it to the same repository host 1 is connected to from ip 10.42.1.10. There may be a way to get ovirt to connect to another ip address instead of the ip domain address for the first host. I'm attaching logs: ----> /var/log/ovirt-engine/engine.log 2020-03-31 09:13:03,866+03 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghan dling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-90) [7fa128f4] EVENT_ID: VDS_SET_NONOPERATIONAL_DOMAIN(522), Host host2.school34.local c annot access the Storage Domain(s) <UNKNOWN> attached to the Data Center DataCenter.

Failing to redeploy self hosted engine
by Maton, Brett 05 Apr '20

05 Apr '20

I keep running into this error when I try to (re)deploy self-hosted engine. # ovirt-hosted-engine-cleanup # hosted-engine --deploy ... ... [ INFO ] TASK [ovirt.hosted_engine_setup : Fail with error description] [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The host has been set in non_operational status, deployment errors: code 9000: Failed to verify Power Management configuration for Host physhost01.example.com, fix accordingly and re-deploy."} I shut down all of the VM's and detached the storage before cleaning up and trying to re-deploy the hosted engine, first time I've run into this particular problem. Any help appreciated Brett

Multiple NICs on hosted engine, oVirt 4.3
by Jiří Sléžka 04 Apr '20

04 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 03 Apr '20

03 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. Very much appreciated! - Jayme
