"ovirt-node", or CentOS Stream 8?

> into the existing cluster, and I found out I cannot start any of my VMs on it. After some  tries, I found out the VM simply does not start up with Q35 BIOS. It starts with legacy BIOS, or Q35 UEFI, but not with Q35 BIOS. Blank screen, nothing. The node is slightly newer then others. What could I do with it? I would rather avoid changing chipset on all my VMs to legacy, just to be able to run them on new node....

If cs8, please try downgrading qemu-kvm to 6.0.
6.1 is broken - see other threads on this list and:

https://bugzilla.redhat.com/show_bug.cgi?id=2024605

Latest released ovirt-node should exclude qemu 6.1.

I noticed that qemu-kvm 6.2 was released very recently, didn't hear
any reports about it or try it myself yet.
