Passwordless SPICE console login?
by cen
Hi,
we have all VMs set up with passwordless users, using only keys for
remote ssh login.
When connecting through SPICE console, it prompts for login. Using
something like root/ubuntu with empty password does not work.
Is there a way to do this with keys or is it essental to have a local
user with password (perhaps with restricted SSH) to perform a console login?
Best regards, cen

give cloud-init the VM name
by Luca Contessa
Hi list,
I have an oVirt node 4.4.9 installation with hyperconverged structure, on which i've created a pool of Linux VM (CentOS Stream 8).
I would like set as hostname the name of the VM + a static suffix appended at the end of the name (EXAMPLE: <VM name>.static.suffix ), is there a way to pass to cloud-init the name of the VM and do this via cloud-init?
I've tried to look for something in oVirt and cloud-init documentation and found nothing.
Thanks a lot to everybody for the help and have a nice day.

Existing Qemu/KVM Host as a node
by atkinson.unt＠gmail.com
Is there any information on possibility of using an existing Qemu/KVM host as a node? I like the look and feel of oVirt, and want to use it on my main hypervisor, but I don't want to have to rebuild or import 20 VMs, one of which happens to also be my router. If I were to set up a management unit, and add my existing host as a node, would it be able to import or recognize and use existing VMs?

Linux VMs cannot boot from software raid0
by Strahil Nikolov
Hi All,
I recently migrated from 4.3.10 to 4.4.9 and it seems that booting from software raid0 (I have multiple gluster volumes) is not possible with Cluster compatibility 4.6 .
I've tested creating a fresh VM and it also suffers the problem. Changing various options (virtio-scsi to virtio, chipset, VM type) did not help .
Booting from rescue media shows that the data is still there, but grub always drops to rescue.
Any hints are welcome.
Host: CentOS Stream 8 with qemu-6.0.0oVirt 4.4.9 (latest)VM OS: RHEL7.9/RHEL8.5

how to debug sanlock issue
by Jiří Sléžka
Hello,
I have 3 node HCI cluster with glusterfs. oVirt 4.4.9.5-1. In last 2
weeks I experience 2 outages where HE and all/some vms were restarted.
While digging in logs I can see that sanlock cannot renew leases and it
leads to killing vms as is very good described in [1].
It looks to me like some hw issue with one of the hosts but cannot find
which one.
for example today's outage restarted vms on hosts 1 and 2 but not 3.
Sanlock logs
there are these lines in /var/log/messages on host 2 (ovirt-hci02)
Jan 13 08:27:25 ovirt-hci02 sanlock[1263]: 2022-01-13 08:27:25 1416706

but not on hosts 1 and 3. Could it indicate that there could be storage
related problem on host 1?
could you please suggest further/better debugging approach?
Thanx a lot,

External engine CentOS 8.4 and 4.4.8 to Rocky Linux 8.5 and 4.4.9
by Gianluca Cecchi
Just wanted to share what in subject and feedback/comments welcome.
Starting env is an external engine on CentOS 8.4, updated up to late
September, with 4.4.8 async 2 (ovirt-engine-4.4.8.6-1.el8.noarch.rpm) and
kernel 4.18.0-305.19.1.el8_4
[g.cecchi@ovmgr1 ~]$ cat /etc/centos-release
CentOS Linux release 8.4.2105
I migrated to Rocky Linux 8.5 and then run engine-setup to take it to
current 4.4.9 level.
The system is a VM on a vSphere environment.
Currently there are 3 hosts with CentOS 8.4, that I'm going then to migrate
to Rocky Linux too.
Downloaded the current migration script from
https://raw.githubusercontent.com/rocky-linux/rocky-tools/main/migrate2ro...
chmod +x migrate2rocky.sh
My engine needs a proxy to exit on the internet and the script doesn't
check my /etc/yum.conf configuration
so I set
export https_proxy=http://my_proxy:my_proxy_port
export http_proxy=http://my_proxy:my_proxy_port (not sure if this
necessary...)
otherwise when you run the script you get
curl: (7) Failed to connect to dl.rockylinux.org port 443: Connection timed
out
Error downloading the Rocky Linux signing key.
then as root
./migrate2rocky.sh -r
notable things observed:
. some packages from ovirt repos are gathered too... I don't know if
correct in this stage...
Running dnf update before we attempt the migration.

Re: How-to get oVirt host certificated date
by Konstantin Shalygin

Anybody?
@Sandro please help
engine make check once per day and print to logs
How can we run a manual check or see info in PostgreSQL database? This is required because the days until the end of the certificate's life expire, waiting for the next day in order to understand the result of deploying a new certificate is a strange situation
Thanks,

VFs Mellanox
by Jorge Visentini
Hi all.
Is it possible to use the Mellanox VFs with bridge from VMs?
My switch is configured as a trunk accepting VLAN 1000.
I configured Mellanox ConnectX-3 to create 2 VFs. 1 VF I used for iSCSI on
VLAN 1000 (it worked) and another VF I set up a bridge on VLAN 1000 to use
on the VMs.
What is happening is that the VM's mac hits the switch on VLAN 1000, but
has no traffic.
Below are some images of my setup...
*Switch:*

*oVirt Host:*

*oVirt Guest VM:*

Can anyone give a little help?
All the best!
