Restart oVirt-Engine
by Jeremey Wise
How ,without reboot of hosting system, do I restart the oVirt engine?
# I tried below but do not seem to effect the virtual machine
[root@thor iso]# systemctl restart ov
ovirt-ha-agent.service ovirt-imageio.service
ovn-controller.service ovs-delete-transient-ports.service
ovirt-ha-broker.service ovirt-vmconsole-host-sshd.service
ovsdb-server.service ovs-vswitchd.service
[root@thor iso]#
# You cannot restart the VM " HostedEngine " as it responses:
Error while executing action:
HostedEngine:
- Cannot restart VM. This VM is not managed by the engine.
Reason is I had to do some work on a node. Reboot it.. it is back up..
network is all fine.. Cockpit working fine... and gluster fine.. But
oVirt-Engine refuses to accept the node is up.

Host deploy failure: Configure OVN for oVirt
by stephan.badenhorst＠fnb.co.za
Good day,
I am running into a problem during host deploy via the oVirt engine GUI since upgrading to ovirt-engine-4.5.5-1.el8. The "Configure OVN for oVirt" task seem to fail when trying to run the vdsm-tool ovn-config command. Host deploy used to work fine when the engine was on version 4.5.4.
Anyone that can guide me on the right path to get past this issue?
Does not seem to be a new problem - https://lists.ovirt.org/archives/list/users@ovirt.org/thread/IDLGSBQFX35E...

Uploading .iso image with REST API creates <id>.meta with wrong DISKTYPE value
by markul11＠protonmail.com
When creating file (.iso image) with the web GUI the .meta file has DISKTYPE=ISOF, but when using REST, DISKTYPE=DATA and the file is not listed on the "Attach CD" drop down when creating a new vm.
Using API is the only way for me cos I can't find a fix to a connection problem from Firefox/Fedora 39 to the web GUI, so all transfers end up as "suspended by the system".
I am using the following POST to crate the file:
curl -k -u "admin@internal:secretpw" -X POST \
-H "Content-Type: application/xml" \
-d '<disk><name>Rocky-9-latest-x86_64-boot.iso</name><alias>Rocky-9-latest-x86_64-boot.iso</alias>\

Unable to access ovirt Admin Screen from ovirt Host
by louisb＠ameritech.net
I've reinstalled ovirt 4.4 on my server remotely via cockpit terminal. I'm able to access the ovirt admin screen remotely from the laptop that I used for the install. However, using the same URL I'm unable to gain access to the admin screen.
Following the instruction in the documentation I've modified the file: /etc/ovirt-engine/engine.conf.d/99-custom-sso-setup.conf, to reflect the DNS name and I enter in the IP address. But I'm still unable to access the screen from the server console.
What else needs to change in order to gain access from the server console?
Thanks

VM has been paused due to no Storage space error.
by suporte＠logicworks.pt
Hello,
running ovirt Version 4.5.4-1.el8 on Centos 8, randomly we have this error:
VM has been paused due to no Storage space error.
We have plenty of space on the iSCSI storage. This is a preallocated disk, VirtIO-SCSi.
No user interaction. It happens, so far, with 3 VM, Windows and Ubuntu.
This service was stopped: dnf-makecache.service
This is what I found on the engine log:

oVirt slow backups from ISCSI storage domain to nfs target
by Don Dupuis
Hi
I am using oVirt 4.4.10.7 with vms on iscsi Lenovo DE-6600F(nvme interfaced
ssds). Backing up thin vms performance is fine, but with preallocated
disks, backups to nfs storage with 200Gb interface is only transferring
qcow2 image to nfs at 140MiB per sec. Why is qemu-nbd so slow with
preallocated images? Does anyone have any issues related to this? Any help
would be appreciated. I have made iscsid.conf changes, linux kernel boot
changes, and still the same performance.
Thanks

oVirt: Migration recommendation to move from CentOS Stream 8 to 9
by dadamysus＠proton.me
I have inherited the admin duty to maintain a a small oVirt cluster featuring 2 nodes running oVirt 4.5.4 based on the CentOS Stream (using the official Node ISOs) running on physical machines, including a hosted engine. Sadly, the documentation is a bit on the "light side" and the official oVirt documentation can be overwhelming at times.
As CentOS Stream 8 is no longer supported we would like to migrate the nodes to either CentOS Stream 9 using the NG node ISOs or to Rocky Linux 9 - but I guess using the official ISOs seems like the smoothest path. Still, I would like to know what the general steps are to migrate without setting up a entirely fresh cluster.
Is it possible to migrate by setting up an CentOS Stream 9 node in the existing cluster and to deploy a new engine from there?
Is it possible to migrate VMs without downtime in this process?
Ideally, does anyone have some kind of step-by-step guide to get from CentOS Stream 8 to 9 using the oVirt Node ISOs?
Or is it possible to upgrade the existing nodes to CentOS Stream 9 and deploy a new hosted engine from there without creating an entirely new node?
And yeah, I have already searched this list for answers (https://lists.ovirt.org/archives/list/users@ovirt.org/thread/BE5BS4MJSJ4F...) but that thread lacks some the mentioned details.
