How to enable nested virtualization

Hi all, We are trying to run virtual box in a vm that is running over ovirt platform. I had followed the instruction to enable nested virtualization on host as described in this document https://ostechnix.com/how-to-enable-nested-virtualization-in-kvm-in-linux/ However I was not able to enable nested virtualization to the vm since nothing is listed from virsh console. Also tryed to edit vm configuration lookig up for "cpu mode" or "copy cpu configuration as host" Also from oVirt admin portal I had enabled host for nested virtualization through Compute > Host > selected Host > edit > Kernel Nested virtualization checked. But the host still returns: $ cat /sys/module/kvm_intel/parameters/nested N

kvm host becomes non operational after breaking a bonding interface
by LS CHENG 02 Mar '21

Hi I have created a couple of bonding interfaces in the administrator portal, due to some miss configuration I had to break the bond interfaces, what I observe is that after breaking the bonding interfaces the KVM host becomes non operational and it stays in such state unless I add the bonding interfaces back. Anyone have observed this behaviour? Thanks

2 Node oVirt Cluster

Hey there, I tried using oVirt for some time now and like to convert my main Proxmox Cluster (2 Nodes + RPI for Quorum) to oVirt. But I obvioulsy need three servers to do HA. Now I am asking myself: can't I just use the PI as an arbiter node for the Selfhosted-Engine on gluster? I tried running the playbook already, but it's always failing and even if the gluster deployment would go through, it would most likely fail aftwards, right? Before I waste too much energy and time into that, does anyone of you guys use a 2 node cluster? And no I can't add another node (energy + space + money)! Also I know with doing that I'm totally on my own etcetera Thanks!

oVirt4.1 add host error. can i upgrade from 4.1 to 4.4? without updating sequentially 4.1-4.2-4.3-4.4

HI! There is an oVirt 4.1 self-hosted engine cluster of two hosts and a storage connected via iscsi. When trying to add another host, it gives an error: "ERROR otopi.context context._executeMethod:151 Failed to execute stage 'Setup validation': Cannot locate vdsm package, possible cause is incorrect channels". Older hosts on Centos 7.5.1804, last on Centos 7.9.2009. Is it possible to go from 4.1 to 4.4 using the third host as the main one for the transfer?

Cant add vm network with vlan to bonded interface
by murat.celebi＠dbpro.com.tr 01 Mar '21

Hello, I am new to ovirt and try to migrate my companies vmware infra to ovirt. The Engine setup went fine without any problems. These are the steps which I am doing and having problems. 1. Prepare the KVM host by installing the RPM's. 2. Add the kvm host to the engine. Everything is working fine at this point. 3. I am creating a new Network for vm usage named VLAN10. And I am tagging the network with vlan id 10. 4. I am bonding two 25Gb/s interface's with balance-xor mode with the name bond1. 5. When I add the network VLAN10 to the bond1 interface I cant see the logical network assigned to the bond. After this step I am not able to delete the bond since I am getting errors when I try to delete the bond. Any help would be greatly appreciated. Thank you
