[ovirt-users] Re: Unable to upload or download iso via admin portal

[Adam Puchejda]

Hi Konstantin, 

I was reading your post and wonder that maybe you could help with a similar 
issue as well. I also have a problem with certificates and iso/file upload 
(plus an additional but probably connected noVNC case) but on a Windows 11 box. 
The thing is that when I run admin portal (this is a hosted-engine setup) from 
a Linux box, one of the KVM hosts, everything (both upload/noVNC) is working 
fine, but when run from a Windows box... it doesn't. 


On Linux, I just added the ovirt certificate to the browser root trust store. 


On Windows, the same setup is not working. It seems that for Chrome and Edge 
the root trust stores for browsers and the OS itself are the same, for Firefox 
there is a difference as it has - as I understand - its own root trust store. 
Either way, after adding certificates to these stores, I can only get the 
browser not to flag the connection as insecure, but both upload and noVNC are 
not working. As I have mentioned, this problem occurs only under Windows, not 
Linux. 


I would appreciate any help. 


Thanks and best wishes, 

Adam

Hi,
I think that you might simply need to restart ovirt-imageio-proxy service 
because it potentially uses the old certificate/different
from the one used by ovirt-engine service.

And in general I would suggest to troubleshoot that using 
https://myhomelab.gr/linux/2020/01/20/replacing_ovirt_ssl.html

You should be able to troubleshoot that using 'curl'/openssl commands: in the 
way that it relies on system trust of root CAs and trying engine URL
vs. image-proxy URL might reveal more information. This might mean that you 
ignore browser (and its own store of certificate/trust settings...), but start 
from point that there is storage of root CAs
and trust exists because HTTPS endpoint provides certificate chain: server 
certificate plus certificate of sub-CAs (if needed) that is ultimately signed 
by root CA that trusted by your system.

Konstantin

[ovirt-users] How to build network load graphs

[Артур Кириллов]

After updating Overt to 4.5.4, the network load graphs disappeared. Q: How
is charting organized? What certificates are involved in data exchange?

[ovirt-users] Ovirt FQDN is not routing correctly and problems with CentOS 9

[aleksiallula]

I tried to configure ovirt for FQDN with local server but can not get it to 
work.

This is what I added to /etc/hosts:

10.0.0.50   server.ovirt.com
10.0.0.51   server.ovirt2.com

My hostname is server.ovirt.com and my IP address is 10.0.0.50. 10.0.0.51 is 
the hosted engine IP. I have added server.ovirt.com to "DNS search domains" of 
network card.

I ask at the same time: is the difference between hosted engine and 
hyperconverged that with hyperconverged I could add the host to existing hosted 
engine ?

First I tried to install OVirt to CentOS 9, but there is no "virtualization" 
menu at the OVirt main menu. So, I can not add the hosted engine setup. Now I 
try to setup the OVirt for CentOS 8 with this manual: 
https://anthonyspiteri.net/ovirt-kvm-homelab-1 and 
https://anthonyspiteri.net/ovirt-kvm-homelab-2.

Any ideas how can I setup the FQDN and OVirt to work with CentOS 8 or 9 ?
Is there some working repository where I can download the hosted engine version 
OVirt for CentOS 9 ?

[ovirt-users] Re: 4.5.2 hosted-engine deployment failed

[Hans Vader]

Hi all,


I actually have the same problem and opened a thread via web.

https://lists.ovirt.org/archives/list/users@ovirt.org/thread/3VYW4CP74TN24I7ZXD4OCKOLNRA2QGBS/ 
contains a bit of information.


Yet I don't know if it fails at the exact same step.

Could this have something to do with the announcement "Suggestion to 
switch to nightly" from Sandro?



Best regards

I couldn't find any particular error in setup log, it just failed without 
pointing out any reason. I've tried on ovirt node (el9 and el8) and RHEL 8.7.

[ovirt-users] vm has very slow write speed on posix compliant fs disk.

[arc]

Hi,

we have noticed that we get around 30MB/s of write speed per vm in oVirt on our 
datastore that is a GPFS filesystem mounted as posix compliant fs. Read speeds 
are around 1.5-3.3GB/s.

We tested directly on the mount from the host cli with some benchmarking tools 
and from the host directly into the gpfs filesystem we get line speeds but from 
vms we dont..

does anybody have some clues to what is going on and what to try?

Hi,

could you please share the whole log file
/home/yongsheng/f419/var/log/ovirt-engine/setup/ovirt-engine-setup-20230418170928-1v6iod.log
?
The lines you were showing are just a consequence of stopping the setup due
to previous error. The real error is earlier in the log (you can search for
lines with "ERROR" levels)

Regards,
Martin

[ovirt-users] Administration portal doesn't load.

[kushagra.gupta--- via Users]

I have an odd situation:
When I go to
https://ovengine/manager-engine.com/webadmin/?locale=en_US

after authentication passes...
it shows the top banner of

oVirt OPEN VIRTUALIZATION MANAGER

and the


Loading ...


in the center. but never gets past that. 

I also followed the thread and tried opening the admin portal in the 
private/incognito mode but I still face the issue.

I rebooted the hosted engine as well but I am still facing the same issue.
When I trigger the above url, in the engine.log, following logs are created:

As you can see there are no error logs.

But at the same time I am able to see some prior errors in the engine.log file:

Also I can see that there is a connection between the ovirt-host and the 
hosted-engine:
