what does dwh db contain?
by Nathanaël Blanchet
Hello,
I need to understand which user removed a vm 2 months ago, but I can't
recover such info into engine.log (that default rotate is 20).
I gave a quick look to the dwh database: I'm able to find the removal
date, but not the associated user.
Is there a way to get this information?

Live ("any") disk migration between storages KILLS a virtual machine with Windows (UEFI) !!!
by Patrick Lomakin
The weekend went horribly. I created a second storage domain in order to move all the virtual machines to a higher performance RAID array (From RAID6 to RAID10). My mistake was trying to move two Windows domain controllers from one storage domain to another. The problem is that when I "live" moved the virtual machine disk between storage domains, my Windows Server 2019 virtual machines worked fine until the next reboot. After a reboot, the machine just won't start and throws an error - Status: 0xc0000428 - The digital signature for this file couldn't be verified. Moving back to the "old" domain doesn't help.
None of the procedures with VMs worked (Re-create boot area, turn on kernel flag - bcdedit.exe /set nointegritychecks on). I am ready to help and interested in developing Ovirt. I can also provide more information to developers if needed.

It looks like engine sent:
parent_checkpoint_id: None
This issue was fix in engine few weeks ago.
Which engine and vdsm versions are you testing?

This is likely a result of the first error. If starting backup failed the

Re: CPU Compatibility Problem after Upgrading Centos 8 Stream Host
by k.gunasekhar＠non.keysight.com
I also end up with the same problem today. How did rollback yum i see many yum updates in the yum history.
Here is what the error says.
The host CPU does not match the Cluster CPU Type and is running in a degraded mode. It is missing the following CPU flags: model_IvyBridge, spec_ctrl. Please update the host CPU microcode or change the Cluster CPU Type.

Adding a 4th compute host to a HCI environment
by David White
Hello,
Is there documentation anywhere for adding a 4th compute-only host to an existing HCI cluster?
I did the following earlier today:
- Installed RHEL 8.4 onto the new (4th) host
- Setup an NFS share on the host
- Attached the NFS share to oVirt as a new storage domain
- I then turned the NFS share into a "backup domain"
- Once that was done, I installed ovirt-release44.rpm, followed by some ovirt packages:
- yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm
- yum install cockpit-ovirt-dashboard vdsm-gluster ovirt-host
- I then logged into the oVirt Manager Web UI, navigated to Hosts, and clicked on New
- I successfully added the new host to the cluster
Once this was all done, load average on all 3 of my original HCI nodes started to go through the roof.
I've seen servers' load average go through the roof before when NFS shares are down, so I suspect that something happened to the NFS share when I went to add the host as a compute node.
In an effort to get things stabilized, I wound up yanking the new host out of oVirt, as well as the NFS share, at which point things did stabilize again.
My goal here:
- Setup the host as a compute-only host (don't participate in the gluster cluster)
- Setup the NFS share for backup purposes
Writing this email and reviewing my bash history, I think one of the places I went wrong was I installed vdsm-gluster. I don't think I need that, do I?
Is what I'm trying to do possible?

Guest CPU compatibility issues on upgraded host - RHEL 8
by David White
I have oVirt 4.4.6 running on my Engine VM.
I also have oVirt 4.4.6 on one of my hosts.
The other two hosts are still on oVirt 4.4.5.
My issue seems slightly different than the issue(s) other people have described.
I'm on RHEL 8 hosts.
My Engine VM is running fine on the upgraded host, as is one of my Ubuntu guests.
However, it seems like I'm not able to migrate *ANY* other guests over the new host. The oVirt UI just indicates that for whatever reason the upgraded host isn't available / compatible for a VM to be migrated to.
I'm not sure how or why this 1 Ubuntu guest VM was able to get migrated, but it looks like its working just fine.
I did try:
yum downgrade edk2-ovmf
Base on other people's comments. But I'm not sure how long to wait, or what else to try, to try to get my upgraded host operational again.

issue creating disk with rest api using json format
by Pascal D
I am unable to create disk using JSON however the same query in XML works great. In Json I get the following message back:
{
"detail": "For correct usage, see: https://ov1.butterflyit.com/ovirt-engine/apidoc#services/disks/methods/add",
"reason": "Request syntactically incorrect."
}
Both use POST /ovirt-engine/api/disks and the content-type is either application/json or application/xml
Here is the request in JSON:
{
"id": "866770c3-acf9-4f67-b72c-05ed241908e4",
"name": "mydisk",
"description": "test disk",
"bootable": false,
"shareable": true,
"provisioned_size": 10240000000,
"interface": "virtio",
"format": "cow",
"storage_domains": {
"storage_domain": {
"name": "VMS"
}
}
}
And here it is in XML
<disk id="866770c3-acf9-4f67-b72c-05ed241908e4">
<bootable>false</bootable>

Ovirt 4.4.6.8 High Performance VM quirkiness
by Don Dupuis
I created a high performance vm and everything is fine. I stop the virtual
machine and make edits to it and again runs correctly. I shutdown the vm
and click the edit tab to look at what I changed and it is now back to the
defaults and my edits are gone. Is this now the intended result. I was
using the same settings in 4.3 and never exhibited this behavior. What I
have observed so for is that I disabled Headless, disabled cpu pinning, and
changed numa config. When I shutdown the vm, they revert to default of
Headless enabled, cpu pinning is set and the numa config changed. This is
not what I expect to happen. Has anyone else noticed this behavior?
Thanks
