Creating new system
by vkasabiev＠gmail.com
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.

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

Nightly build to stable
by Erdősi Péter
Hi,
I've installed the Version
4.5.4-0.2.master.20221007083550.gitb24d914c24.el8 few days before (since
the stable not working at the time)
Is there any way to make this installation following the stable updates
if the 4.5.4 became stable?
Regards,
Peter

[4.4.7] The latest guest agent needs to be installed and running on the guest
by Christoph Timm
Hi list,
I have upgraded my oVirt from 4.4.4 to 4.4.7 and notice that some VMs
have issues to report the performance information via the guest agent.
I see the following message on the VMs: The latest guest agent needs to
be installed and running on the guest
The qemu-guest agent is installed on VMs (the VM OS is CentOS 8).
Any advice how to troubleshoot this?
I can see the stats will be presented in the GUI, if I migrate the VM to
a different host.
Best regards
Christoph

Linux direct boot kernel/initrd from Data Domain
by Francesco Zaccaria
Hi,
I'm using Ansible ovirt_vm module for automating VM Linux direct boot, but it seems kernel/initrd are not working if uploaded to Data Domain. Same problem starting VM from Ansible playbook and from OLVM web portal.
I uploaded kernel/initrd (extracted from Oracle Linux 8.6 ISO) on a Data Domain, both via webconsole and REST APIs; according to doc (http://ovirt.github.io/ovirt-engine-api-model/master/#types/operating_sys...) kernel/initrd can be on ISO storage domain, but it's a deprecated OLVM feature.
I have an OLVM cluster (Version 4.4.8.6) with 1 manager, 2 hosts and 2 Fibre Channel Data Domains (I always use first one for VMs).
Uploading kernel/initrd on hosts installation works like a charm:
kernel_path: /tmp/vmlinuz
initrd_path: /tmp/initrd.img
kernel_params: "inst.ks.sendmac inst.ks=https://[webserver]ks.cfg ip={{ item.static_ip }}::{{ item.gateway }}:{{ vm_netmask }}::{{ item.nic_name }}:off net.ifnames=0 {% for ip in dns_server %} nameserver={{ ip }} {% endfor %}"
kernel_params_persist: false
While using Data Domain is not working (disk ID is needed because of alias names not unique):
kernel_path: iso://69146b00-4779-47b3-95eb-d2c9bb84e588
initrd_path: iso://6212fb79-e4bb-42ca-ac5c-1da0d0dba7dc
At VM booting I get this error, reporting path which is present just on first host (why not on both?):
Exit message: unable to set security context 'system_u:object_r:virt_content_t:s0' on '/rhev/data-center/mnt/blockSD/38730c94-68b1-4fde-8a31-8c3870925996/images/69146b00-4779-47b3-95eb-d2c9bb84e588/9797758e-d038-4a50-a188-e3601ad0e539': No such file or directory.
Finally, using same full ISO CD attached to VM:
kernel_path: iso://b9e8fad1-9884-46a4-8203-9ac73b69ecac
initrd_path: iso://b9e8fad1-9884-46a4-8203-9ac73b69ecac
I get permission denied (link seems missing, though image is correctly used when booting from CD):
Exit message: internal error: process exited while connecting to monitor: 2022-10-26T11:07:07.779657Z qemu-system-x86_64: -blockdev {"driver":"host_device","filename":"/rhev/data-center/mnt/blockSD/38730c94-68b1-4fde-8a31-8c3870925996/images/b9e8fad1-9884-46a4-8203-9ac73b69ecac/48b92374-b4cb-45f6-b388-883abbf691c2","node-name":"libvirt-5-storage","auto-read-only":true,"discard":"unmap"}: Could not open '/rhev/data-center/mnt/blockSD/38730c94-68b1-4fde-8a31-8c3870925996/images/b9e8fad1-9884-46a4-8203-9ac73b69ecac/48b92374-b4cb-45f6-b388-883abbf691c2': Permission denied.
I found similar issue opened
https://lists.ovirt.org/archives/list/users@ovirt.org/thread/IDIDY6ZLZCRM...
could the problem be ISO path with Data Storage?

by goosesk blabla
Hi,
for backup VM i use script to create snapshot and then attach disks of VM to backupVM where i do copy of this disk . Also i backup OVF file.
for restore , i just upload disk to corupted VM and attach.
But ,, if i want to make some easy restore GUI,, it will be easier if i build OVA file from restored OVF and raw disks and then through API just import VM from OVA.
The problem is i cannot find any correct way to to build correct OVA file for OVIRT.
is there some playbook or script or way ho to do ?
