POWER9 (ppc64le) Support on oVirt 4.4.1

by Vinícius Ferrão

Hello, I was using oVirt 4.3.10 with IBM AC922 (POWER9 / ppc64le) without any issues. Since I’ve moved to 4.4.1 I can’t add the AC922 machine to the engine anymore, it complains with the following error: The host CPU does not match the Cluster CPU type and is running in degraded mode. It is missing the following CPU flags: model_POWER9, powernv. Any ideia of what’s may be happening? The engine runs on x86_64, and I was using this way on 4.3.10. Machine info: timebase : 512000000 platform : PowerNV model : 8335-GTH machine : PowerNV 8335-GTH firmware : OPAL MMU : Radix Thanks,

Generally speaking, you should follow the hosted-engine backup and restore flows/documents. I strongly suggest to test this first on a test machine before production. You can take a backup without downtime. Restore on some machine (can be a VM, with nested-kvm) that has no access to your production storage and hosts (to make sure the restored engine won't start managing them/competing with the production one). See that all looks good. Then plan production... Good luck and best regards, -- Didi

Migrate hosted-engine to new storage domain

by Matthew.Stier＠fujitsu.com

I've migrated my iSCSI storage to a new array, and the only thing remaining is to migrate the hosted-engine. Any directions on how I should proceed. I understand that I will need to back-up the existing, create a new hosted-engine on the new storage, specifying the backup a reference. I just would like to see a step-by-step, so I know I am doing everything, and in the right order.

Select host for image upload

by C Williams

Hello, I am having problems selecting the host that I want to use for .iso and other image uploads via the oVirt Web Console. I have 20+ servers of varying speeds. Somehow oVirt keeps wanting to select my oldest and slowest system to use for image uploads. Please Help ! Thank You ! C Williams

Q: Failed creating snapshot

by Andrei Verovski

Hi, I have oVirt 4.4 with nodes 4.2.8 Attempt to create snapshot failed with: EventID 10802 VDSM node11 command SnapshotVDS failed: Message timeout can be caused by communication issues. Event ID 2022 Add-disk operation failed to complete. However, snapshot is on disk since VM now takes 1200GB instead of 500. Yes snapshot list in VM details is empty. How to recover disk space occupied by unsuccessful snapshot ? I looked at /vmraid/nfs/disks/xxxx-xxxx-xxx/images and there are no distinctive files which I can identify as snapshot. Thanks in advance. Andrei

ovirt installation with proxy or katello

by Markus Schaufler

Hi, in our environment we need to either specify proxy settings or use foreman/katello repositories. I'd like to test both ways but the installer with the ansible scripts behind don't seem to use the hosts settings. Where do I have to adopt the install scripts and will there be in future a GUI option to specify those things? Can't understand why disconnected environments or environments with proxies aren't better taken into consideration...? Thanks in advance, Markus

Question about OVN MTU

by Strahil Nikolov

Hello All, I would like to learn more about OVN and especially the maximum MTU that I can use in my environment. Current Setup 4.3.10 Network was created via UI -> MTU Custom -> 8976 -> Create on External Provider -> Connect to Physical Network So my physical connection is MTU 9000 and I have read that Geneve uses 24 bits (maybe that's wrong ?) , thus I have reduced the MTU to 8976. I did some testing on the VMs and ping with payload of '8914' was the maximum I could pass without fragmenting and thus the MTU on the VMs was set to 8942. Did I correctly configure the test network's MTU and am I understanding it correctly that we need extra 34 bits inside the network for encapsulation ? I have checked https://www.ovirt.org/develop/release-management/features/network... but I don't see any refference how to calculate the max MTU. Best Regards, Strahil Nikolov

different rendering chrome and firefox and corruptions in both

by Gianluca Cecchi

Hello, I'm using Fedora 31 with google-chrome-stable-86.0.4240.111-1.x86_64 firefox-82.0-4.fc31.x86_64 Engine was deployed from a CentOS Linux 8.2 host and then with hosted engine wizard, using the appliance rpm (Package ovirt-engine-appliance.x86_64 4.4-20200916125954.1.el8) Connecting to the same 4.4.2 engine I get: 1) different landing page graphics firefox: https://drive.google.com/file/d/142Ch7qXmmIP9sQQCS1rD75yexX64RmSu/view?us... chrome: https://drive.google.com/file/d/1KPvlNk65ltIBhr8GFdVm-GMtfq1Elt7J/view?us... 2) corruption in several editing pages in firefox, where a sort of top white part seems to compromise the lower part of the window, making impossible to complete. eg in new network I don't see the lower part related to MTU...: https://drive.google.com/file/d/18aQfDbl_9R9oQsTMwebJSiRZHETkUWIc/view?us... 3) in Stotrage --> volumes page if I click on a volume, firefox shows no problem, but chrome gives a gui exception: https://drive.google.com/file/d/1svzQjrGctRMQFvZEpW9zpOlUbv8XXl3Q/view?us...

Discard after Delete

by Joris DEDIEU

Hi list, I forgot to check "Discard after Delete" when creating a new volume. Is there a way (other than to empty the volume) to reclaim free blocks. In https://bugzilla.redhat.com/show_bug.cgi?id=981626 I read about blkdiscard, but as far as I understand it will erase my VMs ... Thanks for your answers Joris
