Hosted engine deployment fail because host version does not match cluster version
by emanuele.breuza＠e4company.com
Hello,
I'm Emanuele. I'm interested in setting up a 3 node HA oVirt cluster on RHEL 8.3. Following the oVirt Gluster Hyperconvergence guide, I managed to setup a GlusterFS storage and then I started the procedure to configure a self-hosted engine via cockpit. Unfortunately, I got stack at the "Prepare VM stage".
During this procedure, the automated process paused to let you verify inside the ovirt-engine that your host is OK. Since this is a brand new installation of oVirt, I have only one host configured and it is marked as not-good. The reason reported in the web page is that the host is compatible for v. 4.2, 4.3 and 4.4 but the Cluster is v. 4.5. I tried to execute the upgrade procedure on the host but it was unable to go into maintenance mode.
I tried both ovirt-release44 and ovirt-release-master RPM to load the latest repository but without success. Do you have any suggestion about how to fix the self-hosted engine procedure?
BTW, if I install my server with the oVirt node ISO the procedure works correctly and my host report also 4.5 into the compatibility version list.
Thank you very much for your help!!!

[ANN] oVirt 4.4.6 First Release Candidate is now available for testing
by Lev Veyde
oVirt 4.4.6 First Release Candidate is now available for testing
The oVirt Project is pleased to announce the availability of oVirt 4.4.6
First Release Candidate for testing, as of March 25th, 2021.
This update is the sixth in a series of stabilization updates to the 4.4
series.
How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1
Note: Upgrading from 4.4.2 GA or later should not require re-doing these
steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These
are only required to be done once.
Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> -
Host enter emergency mode after upgrading to latest build
If you have your root file system on a multipath device on your hosts you
should be aware that after upgrading from 4.4.1 to 4.4.6 you may get your
host entering emergency mode.
In order to prevent this be sure to upgrade oVirt Engine first, then on
your hosts:
1.
Remove the current lvm filter while still on 4.4.1, or in emergency mode
(if rebooted).
2.
Reboot.
3.
Upgrade to 4.4.6 (redeploy in case of already being on 4.4.6).
4.
Run vdsm-tool config-lvm-filter to confirm there is a new filter in
place.
5.
Only if not using oVirt Node:
- run "dracut --force --add multipath” to rebuild initramfs with the
correct filter configuration
6.
Reboot.

Ovirt Node (iso) - OK to enable Centos-BaseOS/Centos-Appstream repos ?
by morgan cox
Hi.
I have installed Ovirt nodes via the ovirt-node iso (centos8 based) - on a fresh install the standard CentOS repos are disabled (the ovirt 4-4 repo is enabled)
As part of our company hardening we need to install a few packages from the Centos repos.
Can I enable the CentOS-Linux-AppStream.repo + CentOS-Linux-BaseOS.repo repos or will this cause issues when we update the node ?
Thanks

Problem to create provider
by miguel.garcia＠toshibagcs.com
We have a problem to create the first provider in the ovirt cluster by following next steps:
Go to Administration - Provider - click Add
Filled up fields for new provider with next information:
Name: ovirt-provider-ovn
Type: External Network Provider
Network Plugin: oVirt Network Provider for OVN
Provider URL: https://ovirthostname:9696
Uncheck Read-only
Check Request authentication
username : admin@internal
Protocol HTTPS
Hostname ovirthostname
API port: 35357
Click Test
Result:
Test Failed (unknow error)
Log file:

I think I would expect to ask the certificate to complete connection but does not ask for certificate at all.
Any idea how to solve this?

VDSM command failed:Received fatal alert certificate_expire
by fmendoza＠red.com.sv
Recently Ovirt sent certificate expiration messages. And it does not let me manage the server VMs, I have looked for information about this and I can not find something that is clear. The version of Ovirt that I own is 3.6.3.4-1.el7.cents. I have at least 4 operational VMs of vital importance.
Thanks for the support

websockify + ovirt

with this I can successfully connect to a vm. Now I would like to do the same from spice-web-client but websockify doesn't give me a tls-port. How to could I implement this? Is there a wrapper that exists that I can pass to websockify to do the authentication on the port + 1 (it seems it is always the next port)
Thanks in advance for your help

supervdsm failing during network_caps
by Alan G
Hi,
I have issues with one host where supervdsm is failing in network_caps.
I see the following trace in the log.
MainProcess|jsonrpc/1::ERROR::2020-01-06 03:01:05,558::supervdsm_server::100::SuperVdsm.ServerCallback::(wrapper) Error in network_caps

raise IOError(-err, nl_geterror(err))
IOError: [Errno 16] Message sequence number mismatch
A restart of supervdsm will resolve the issue for a period, maybe 24 hours, then it will occur again. So I'm thinking it's resource exhaustion or a leak of some kind?
Running 4.2.8.2 with VDSM at 4.20.46.
I've had a look through the bugzilla and can't find an exact match, closest was this one https://bugzilla.redhat.com/show_bug.cgi?id=1666123 which seems to be a RHV only fix.
Thanks,
Alan
