[ovirt-users] How to view multi ovirt-manager VM ?

[rak kim]

Hello, I'm kim

I have 7 ovirt-manager running on each service 

I want to manage 7 ovirt-manger on one platform 

Is there any program to view VMs at each ovirt-manager  for one platform ? 
(like multi-cloud platform ?)

I guess I just need to be able to control/view the VM.

[ovirt-users] Re: Ovirt 4.4.10 running on RHEL 8.7

[eshwayri]

I am running 4.5.4 on RedHat EL8.7(~ish), so the latest is possible; not so 
sure about 4.4.10.  I had to look through my logs to see what order I did 
things in.

04/29/22 Upgraded to 4.4.9-1
10/08/22 @ 19:19 Upgraded to 4.4.10.2-1
10/08/22 @ 19:43 Installed the new CentOS stream repos (as detailed in the link)
10/08/22 @ 19:46 Installed centos-release-ovirt45
11/27/22 @ 17:46 Upgraded to 4.5.2.5-1
11/27/22 @ 18:21 Upgraded to EL8.6

I suspect I wanted to go to 4.5 on 10/08, but ran into problems.  Waited for 
the next release of 4.5, and actually upgraded about a month later.  It doesn't 
look like I ran 4.4.10 on EL8 -- sorry.  I sort of remember there were issues 
wit the regular release CentOS repos going away, which is why that link has you 
add the new stream repos.  At the same time there were missing packages on the 
oVirt side; not sure if everything was resolved.  I ended up moving up to 4.5.

If you want to upgrade I do recommend you go to 8.6 first, and then at the end 
go to 8.7.  Reason is the "~ish" when I say I am running EL8.7.  You get a 
package collision.

Problem: installed package centos-stream-release-8.6-1.el8.noarch obsoletes 
redhat-release < 9 provided by redhat-release-8.7-0.3.el8.x86_64

With -nobest I am effectively running 8.7, so I tolerate this.  Hoping when 8.8 
comes out this will work itself out.

[ovirt-users] Re: 4.5.4 Hosted-Engine: change hosted-engine storage

[Diego Ercolani]

Thank you very much.
I think the process is very overcomplicated I successfully setup the engine 
installing a fresh engine and then restore the backup... but then, when I 
tryied to register the new storage... everything gone wrong.
There shoud be some shortcircuits that permit to overcome problems in some 
manner... it's not possible that with an error under ansible you have to 
restart from the beginning. Is frustating, megabytes and megabytes of 
unreadable log why these overcomplications?

Currently I'm at the point that I have restored the engine in the localstorage 
but I need to copy it to the destination storage but ansible prefer to exit 
with error. frustrating

this is /var/log/ovirt-engine/engine.log extract:

[ovirt-users] Re: pass-through CPU

[Strahil Nikolov via Users]

If you have hosts with the exact  same cpu, you can enable cpu passthrough and 
set the hosts  from the "Specific Host(s)" section. Also you can set the 
migration mode to "Allow manual and automatic migration".
I guess you already noticed that VMs with CPU passthrough have access to more 
CPU instructions compared to the Virtualized one.
Best Regards,Strahil Nikolov 
 
Hi, 

What are the pro and cons of enabling pass-through CPU ?

It is a greyed option for a VM, unless specific host(s) is/are selected. 
That's the thing : it's possible to select all hosts..., so, it does not make 
difference w/ "Start on any host" option

[ovirt-users] Ovirt 4.4.10 running on RHEL 8.7

[James Wadsworth]

Hi there, 

we currently have ovirt 4.4.9 running on RHEL 8.5. 

Can we upgrade the cluster to ovirt 4.4.10 on RHEL 8.7? 
Do we need to following these steps in this link?

https://www.ovirt.org/download/install_on_rhel.html

Many thanks, James

[ovirt-users] Re: VM backup issue on oVirt 4.4.7

[Don Dupuis]

Sandro
I didn't open a ticket yet as Nvidia doesn't support anything above RHV 4.4
and since RHV moved to maintenance mode, I didn't see a likely chance it
would be looked at. If I call Nvidia support they will tell me what I am
doing isn't supported, so I have to go through our partnership so they will
talk to me. I will talk to them shortly, but I have a customer delivery to
get done and oVirt 4.4.7 does everything I need to do, except now I have
this backup issue that worked in 4.5. I can provide further info if you
need on this issue. Windows guest is 21H2. I will hope to solve vgpu
problem as I will need Windows 11 and Windows 2022 guest working. Thanks
for your support

Don

Do you refer to -ha's dns monitor? This is done by calling 'dig'
without specifying a server, so it uses (by default) your system-wide
settings, usually in /etc/resolv.conf.

If you meant to ask about something else, please clarify.

[ovirt-users] Re: 4.5.4 Hosted-Engine: change hosted-engine storage

[Volenbovskyi, Konstantin]

Hi,
The problem/problems don't seem to be related to HE storage in any way.
As you don't use OVN I would make sure to remove any parameters in answer files 
that mention 'ovn' or something about external providers (and let ovengine 
setup prompt for any values interactively)
and make sure that none of the networks have that 'external network' checkmark 
with ovn as provider in ovEngine GUI
(but yes, I see that you explicitly said 'I don't have OVN in my dump'...)

For Keycloak probably you see the change described in 
https://www.mail-archive.com/users@ovirt.org/msg70682.html and thus it is 
indeed likely that you need to use OVESETUP_CONFIG/keycloakEnable=bool:False

All in all, there are 3 primary things to think of: backup, answers file and 
ovirt version (and of course things like OS/networking aspects...) and you 
might narrow down the troubleshooting by using some test host and then don't use
backup/adapt or don't use answers file.


BR,
Konstantin

by the way I don't use keycloak (I don't have any keycloak table in the engine

I will try to set OVESETUP_OVN/ovirtProviderOvn=bool:True to False before 
ansible launch engine-setup
