CentOS Stream support
by Michal Skrivanek 25 Jan '21

25 Jan '21

Hi all, we would like to ask about interest in community about oVirt moving to CentOS Stream. There were some requests before but it’s hard to see how many people would really like to see that. With CentOS releases lagging behind RHEL for months it’s interesting to consider moving to CentOS Stream as it is much more up to date and allows us to fix bugs faster, with less workarounds and overhead for maintaining old code. E.g. our current integration tests do not really pass on CentOS 8.1 and we can’t really do much about that other than wait for more up to date packages. It would also bring us closer to make oVirt run smoothly on RHEL as that is also much closer to Stream than it is to outdated CentOS. So..would you like us to support CentOS Stream? We don’t really have capacity to run 3 different platforms, would you still want oVirt to support CentOS Stream if it means “less support” for regular CentOS? There are some concerns about Stream being a bit less stable, do you share those concerns? Thank you for your comments, michal

encrypted GENEVE traffic
by Pavel Nakonechnyi 18 Jan '21

18 Jan '21

Dear oVirt Community, From my understanding oVirt does not support Open vSwitch IPSEC tunneling for GENEVE traffic (which is described on pages http://docs.openvswitch.org/en/latest/howto/ipsec/ and http://docs.openvswitch.org/en/latest/tutorials/ipsec/) Are there plans to introduce such support? (or explicitly not to..) Is it possible to somehow manually configure such tunneling for existing virtual networks? (even in a limited way) Alternatively, is it possible to deploy oVirt on top of the tunneled (i.e. via VXLAN, IPSec) interfaces? This will allow to encrypt all management traffic. Such requirement arises when using oVirt deployment on third-party premises with untrusted network. Thank in advance for any clarifications. :) -- WBR, Pavel +32478910884

Unable to live migrate a VM from 4.4.2 to 4.4.3 CentOS Linux host

Right now all my active VMs are with at least a vnic on OVN so I cannot test the scenario of migrating a VM without OVN based vnic. In fact on engine I see only the currently active host in 4.4.2 (ov200) and another host that is in maintenance (it is still in 4.3.10; I wanted to update to 4.4.2 but I realized that 4.4.3 has been out...): [root@ovmgr1 ovirt-engine]# ovn-sbctl show Chassis "6a46b802-5a50-4df5-b1af-e73f58a57164" hostname: "ov200.mydomain" Encap geneve ip: "10.4.192.32" options: {csum="true"} Port_Binding "2ae7391b-4297-4247-a315-99312f6392e6" Port_Binding "c1ec60a4-b4f3-4cb5-8985-43c086156e83" Port_Binding "174b69f8-00ed-4e25-96fc-7db11ea8a8b9" Port_Binding "66359e79-56c4-47e0-8196-2241706329f6" Port_Binding "ccbd6188-78eb-437b-9df9-9929e272974b" Chassis "ddecf0da-4708-4f93-958b-6af365a5eeca" hostname: "ov300.mydomain" Encap geneve ip: "10.4.192.33" options: {csum="true"} [root@ovmgr1 ovirt-engine]# Any hint about the reason of losing OVN config for ov301 and the correct procedure to get it again and persiste future updates? NOTE: this was a cluster in 4.3.10 and I updated it to 4.4.2 and I noticed that the OVN config was not retained and I had to run on hosts: [root@ov200 ~]# vdsm-tool ovn-config engine_ip ov200_ip_on_mgmt Using default PKI files Created symlink /etc/systemd/system/multi-user.target.wants/openvswitch.service → /usr/lib/systemd/system/openvswitch.service. Created symlink /etc/systemd/system/multi-user.target.wants/ovn-controller.service → /usr/lib/systemd/system/ovn-controller.service. [root@ov200 ~]# Now it seems the problem persists... Why do I have to run each time? Gianluca

oVirt 4.4: Self-hosted engine deployment fails with backup restore from 4.3 engine
by Oliver Leinfelder 11 Dec '20

11 Dec '20

Hi there, I'm a bit puzzled about an possible upgrade paths from a 4.3 cluster to version 4.4 in a self-hosted engine environment. My idea was: Set up a new host with a clean ovirt node 4.4 installation, then deploy the hosted engine on this with a restored backup from the production cluster and go from there. This however fails with the following error: 2020-05-27 00:17:08,886+0200 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:103 {'msg': 'non-zero return code', 'cmd': ['engine-setup', '--accept-defaults', '--config-append=/root/ovirt-engine-answers'], 'stdout': "[ INFO ] Stage: Initializing\n[ INFO ] Stage: Environment setup\n C onfiguration files: /etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf, /etc/ovirt-engine-setup.conf.d/10-packaging.conf, /etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf, /root/ovirt-engine-answers\n Log file: /var/log/ovirt-engine/setup/ovirt-engine-setup-20200527001657-fyeueu.log\n Version: otop i-1.9.1 (otopi-1.9.1-1.el8)\n[ INFO ] DNF Downloading 1 files, 0.00KB\n[ INFO ] DNF Downloaded CentOS-8 - AppStream\n[ INFO ] DNF Downloading 1 files, 0.00KB\n[ INFO ] DNF Downloaded CentOS-8 - Base\n[ INFO ] DNF Downloading 1 files, 0.00KB\n [...] ... anwsers from backup config follow ....

If not, what is the appropriate upgrade path? Thank you! Regards Oli

ovirt 4.3 - locked image vm - unable to remove a failed deploy of a guest dom
by 3c.monitor＠gruppofilippetti.it 09 Dec '20

09 Dec '20

Hi all. I've deployed a VM from a corrupted template (it's disk is missing, but I've checked it later...). My Software Version is:4.3 Now, I have an unmanaged VM in inventory and unable to remove it too. It's reference is "locked image". I've restarted ovirt-engine many times on self-hosted engine and hosts too, but no benefits. So, what's now? I've also consulted: https://access.redhat.com/solutions/396753 but still no results. No tasks or items results to be "locked"... Any other ideas? Thanks a lot.

How to install win-virtio Drivers (aka guest tools) silently
by t.hofmann＠klett-it.net 09 Dec '20

09 Dec '20

Hi, i am currently trying to automate an upgrade process from the "old" oVirt 4.3 Guest Tools new one which should using starting with oVirt 4.4 To achieve this I have to install the win-virtio tools quietly. This works even if I use the parameters /install /passive /norestart. But then the oVirt Guest Agent is not installed. Is there a parameter or another way to install it during a silent installation? Thanks in advance. - Tim

Cannot SSH into the self hosted host (going through tutorial)
by jenia.ivlev＠gmail.com 03 Dec '20

03 Dec '20

Hello. I want to install oVirt on my PC and for this purpose I'm following the tutorial which instructed me to make a VM and install there the oVirt self hosted host: https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engin… I cannot SSH to this new oVirt install - I get the error "Connection refused" (Even though I see something listening on port 22 by running `netstat -an`). So I tried stopping `sshd`and I got the same error. Tried to do all of this with `telnet 192.168.122.1 22`, I get the same error "Connection refused". Also, Yum returns "could not resolve host: https://mirrors.fedoraproject.org" I can ping the machine though from my PC. I turned off `firewalld`. `iproute -S` returns `ACCEPT` for everything. My PC is running archlinux and I installed the new VM using "Virtual Machine Manager". Normally, I can easily SSH to any VM I create. Maybe someone know what I'm doing wrong? Thanks kindly Jenia P.S. Running `nodectl check` returns "ok" for all.
