Locking down management network
by David White 05 Nov '22

05 Nov '22

I just discovered that my default management network has the "VM Network" checkbox toggled (on the page where you navigate to Network -> Networks and select the management network). There are no virtual machines associated with the management network. Is it safe to simply edit the management network and uncheck the "VM Network" box? Will anything break (even temporarily) if I do this? Sent with Proton Mail secure email.

Virtual Machine Pools
by Christopher Law 04 Nov '22

04 Nov '22

Hopefully, someone can clarify this a bit for me... From the redhat instructions... "In principle, virtual machines in a pool are started when taken by a user, and shut down when the user is finished. However, virtual machine pools can also contain pre-started virtual machines. Pre-started virtual machines are kept in an up state, and remain idle until they are taken by a user. This allows users to start using such virtual machines immediately, but these virtual machines will consume system resources even while not in use due to being idle." How do users request "take" virtual machines from the pool? For example with a windows machine where we want them to remote desktop into it using RDP? Or does this have to happen through some other portal? Do we have to give users access to the VM Portal? Cheers, Chris.

The latest guest agent needs to be installed
by Christopher Law 04 Nov '22

04 Nov '22

I've got a couple of VMs giving me this error message, "the latest guest agent needs to be installed and running". These VMs have the latest guest agent installed and it is running (virtio-win-1.9.24.iso) The only change to the environment recently was one host has been upgraded from 4.5.2 to 4.5.3. It seems to be the VMs that had at one point ran on this updated host. However, that host is currently turned off they are running on 4.5.2 hosts and have been rebooted. These are Windows Server 2022, 2019 and Windows 11 VMs. I will be updating the rest of the hosts this weekend so can see what happens then. The qemu-guest-agent tools is the same version running elsewhere even tried to repair it no change. Any ideas? Cheers, Chris.

Creating new system
by vkasabiev＠gmail.com 04 Nov '22

Hello, can you pls help me with creating my oVirt system. I installed Centos 7 on one VM and on one physical server. I succesfully configured my VM for oVirtEngie and I can access to web interface. Now I want to configure my physical server to use it as virtualization server(kvm01). My VM has 2 disks, one for system and one for ISO images. My phisycal server also has 2 disks(actually 4 but in 2 Raid1). One for system and one for virtualization storage. Its the second time I try to install everything properly, 1st time I had some issues and decided to reinstall everything. 1st time I successfully added my kvm01 to my ovirtengine, but I couldnt create any VM because I had error with my Data Center, that had status uninitialized, and it seems like I cant initialize it because I have no domain. I'm already confused and decided to ask forum for a correct answer and advices. What shell I do first? I havent added kvm01 to my ovirtEngine yet.

Host restarting with error
by Murilo Morais 03 Nov '22

03 Nov '22

Good morning gentlemen. I have a weird problem with a setup I finished. I'm using oVirt 4.4 Hosted Engine with NFS as Storage Domain, it happens that, if the Storage disconnects, in a few minutes the machine restarts and the red LED lights up as if there had been a crash. I managed to capture a screenshot of this moment once, OOM-Killer killed modprobe which doesn't make much sense as there is no VM other than the Hosted Engine and there is 128G of RAM on the machine.

VNC console connection fails [ovirt 4.5.3.1-1.el8]
by andre.liebe＠gematik.de 02 Nov '22

02 Nov '22

Hello list, is there anybody else out there having problems to connect to a vm console via vnc or is it just me? We are running ovirt-engine 4.5.3.1-1.el8 on up to date ovirt-nodes. I can connect to every virtual machine by spice, but am unable to connect via vnc due to a tls handshake error. Remote-viever just shows "Failed to complete handshake Error in the pull function" (on windows and linux clients). Wireshark tls handshake capture looks supicious to me, server hello message is just 182 bytes long and doesn't coantain a server certificate. Is this normal? sincerely André
