random adapter (NIC) resets on oVirt Node 4.4.6
by Tivon Häberlein 15 Jul '21

15 Jul '21

Hi, I've been trying to get oVirt Node 4.4.6 up and running on my Dell r620 hosts but am facing a strange issue where seemingly all network adapters get reset at random times after install. The interfaces reset as soon as a bit of traffic is flowing through them. Also the logs show nfs timeouts. This only happens after I have installed the host using the oVirt engine and it also only happens when the host is connected to the engine. When the host is in maintenance mode it also seems to work fine. The host and networks work fine when its by itself (I tested right after install using the ISO and also after I have removed the host from the cluster) I cant figure why this is happening. Am I missing something? I've been stuck on this for the last couple of weeks, a bit of help would be much appreciated. Thank you! My cluster is looking like this: Engine: oVirt 4.4.6 - CentOS Linux release 8.3.2011 host1: oVirt 4.4 repository on CentOS Linux release 8.4.2105 host2: oVirt 4.4 repository on CentOS Linux release 8.4.2105 host3 (this is the one I'm trying to install): oVirt node 4.4.6 -- Best regards Tivon Häberlein

Hi Marko, I don't think there is a way to emulate a non-native architecture. Engine doesn't have ARM support and it cannot handle ARM (native or emulated) hosts. You could try to run emulated ARM VMs presented as x86 to Engine using Vdsm hooks but I doubt it would work. I'm afraid the only way is to add ARM support to oVirt. My former colleague has played with running oVirt on Raspberry Pi hosts some years ago (there are traces of that effort in Vdsm) and I think adding ARM support should be, at least in theory, possible. Particular features available would be mostly dependent on ARM support in QEMU and libvirt.

Automatic Shutdown / Startup for Hosted-Engine
by Eugène Ngontang 14 Jul '21

14 Jul '21

Hi, I understood we have to put hosted-engine into maintenance mode and shutdown the VMs if we want to power off the host (otherwise it will reboot). I'm setting up a process to - put the HestedEngine in global maintenance mode (*hosted-engine --set-maintenance --mode=global*) - shutdown the HostedEngine (*hosted-engine --vm-shutdown*) - PowerOff the HostedEngine (*hosted-engine --vm-poweroff*) - Power off the server (*shutdown -P*) Everything works fine and I can start the server back up, remove the HostedEngine from maintenance mode, and it will start automatically running. The issue is when bringing up hosted-engine: all VMs come up but one (*BigIP*) and I am trying to see if there is way to bring it up without having to store the engine password (using the *ovirt_vm* API). At the moment, I am having to look for the BigIP VM and then use credentials to bring it up: it will not come up with 'hosted-engine --vm-start' Is there to make this specific VM start the same time as the others VM automatically when HostedEngine starts? Thanks for your help.

The architecture of the guest is determined by that of the cluster [1] and the latter is either set automatically based on the hosts in the cluster or set explicitly by the user in which case we enforce the hosts to comply with that setting. It could be nice to see it picked up by someone in the community if fully emulated workloads are desired. We don't have anything about this in our backlog at this point. In the meantime, the easiest way to have fully emulated AArch64 workloads would probably be by using a VDSM hook that modifies the VM configuration before it starts (e.g., changing the 'emulator' to /usr/bin/qemu-system-aarch64, changing the 'os' tag, etc). See [2] for how it was suggested to emulate ARM.

How to remove "VM is being cloned" flag in a failed clone VM operation
by Richard Chan 14 Jul '21

14 Jul '21

Hello list, I had an unsuccessful zombie clone VM task - 1. Target: was able to unlock the disks and delete the target VM 2. Source: able to unlock the disks. Now I cannot do anything with the source as it is flagged as "VM is being clone". Is there a way to remove this flag manually? vdms-client Host -> this does not show any tasks outstanding. Thank you.

upgrading to 4.4.6 with Rocky Linux 8
by Jason Keltz 13 Jul '21

13 Jul '21

Hi.. I'm looking to migrate soon from CentOS 7.9 with oVirt 4.3.10 to Rocky Linux 8.4 with oVirt 4.4.6. I'm working on my kickstart of my standalone engine in a VM at the moment. So far, with minimal experience with Rocky Linux, after my kickstart, I was able to run "engine-setup", follow all the defaults and then access my "new" engine via web. I have to explore the actual procedure for installing on my current engine host, and restoring my data. When oVirt team releases new releases, I'm just wondering if you test going from the last previous release (4.3.10 in this case) to each latest release? I know that the documentation says we always need to make sure we update to each individaul major release, but I'm just wondering if this is something that oVirt team tests with each release? I'm very concerned for potential of failed upgrade, and the potential headaches that it could cause. I see the 4.4.6 was released in time with RHEL 8.3. I'd like to use Rocky Linux 8.4 because I believe RHEL has re-enabled mptsas (though I know still unsupported) from 8.4+ which will make things easier. Any additional suggestions or caveats of the upgrade? Thanks for any feedback, Jason.
