Re: Upload Image to NFS Storage Domain Doesn't Work
by Strahil Nikolov 31 Jul '21

When the web UI reports OK (after that 1 sec), do you see a file with the same uuid on that nfs storage ? Maybe you can give some stat output of the file.

How many servers do I need to run oVirt?
by rp.neuli＠yahoo.com 31 Jul '21

31 Jul '21

Hello, sorry for a very basic question. But I searched the net for the basic answer and did not get it. How many servers do I need to run oVirt software? I understand I can access management GUI from anywhere on subnet but naming and they it is explained is confusing to me. I am planning to buy a bigger server (just one to use as compute host) with dual cpu and about 64GB RAM. I am thinking to run my webservers as VM on this proposed machine. I thought it was a level 1 hypervisor (then why does it say some places that I need CentOS or RH on my server?) I also have a FreeNAS server, I was thinking if it was possible to keep my VMs stored on there and run/load/execute them on this so-called-compute server. Will I have to build and keep my VMs (when powered down) on oVirt machine only? finally what will I loose in comparison to free vSphere, if I select oVirt? Thank you. Rajeev

Changing the Password Expiration for a User
by louisb＠ameritech.net 31 Jul '21

31 Jul '21

I've create a new user using ovirt-aaa-jdbc-tool, I'm unable to use the account because the password expiration date has passed. I'm now trying to change the password expiration using the following command: sudo ovirt-aaa-jdbc-tool user edit --password-valid-to=2025-12-31 00:00:00 The above command is not working, I've tried several different formats using double quotes and single quotes, onluy using the date without the time. I've not been able to get anything working, what format should the above command be in? Thanks

VM CPU Topology
by nelson.lameiras＠lyra-network.com 30 Jul '21

30 Jul '21

Hello, We are currently running oVirt 4.3.10 Our oVirt hypervisors (HV) have 2 cpu sockets * 6 cores * HT = 24 vcpu Our VMs (centos7) range globally from 2vcpu to 8vcpu oVirt allows to configure - per VM - the following 3 advanced parameters : virtual_sockets : cores_per_virtual_socket : threads_per_core We make sure that threads per core is always 1 (so no question there) But, for the other 2 parameters, we are unsure of the correct configuration, and if there is a performance penalty on bad configuration. Let's consider a 4vcpu VM 1- Is there a performance difference betwenn 1:4:1 and 4:1:1 configuration ? 2- When should we opt for one or another configuration ? 2- Our VMs total CPU provisionning sum is twice the hypervisors capacity, but they are mostly idle so it is not an issue, but can this influence configuration choice above ? Thank you for any information that can enlighthen us, since we are worried that we are suffering from bad performance due to naive cpu configuration choices.

This year conference community updates
by Sandro Bonazzola 30 Jul '21

30 Jul '21

Hi, as announced we are going to have oVirt online conference coming in September. I would like to give usual community updates in and as part of that I'd like to report about oVirt downstream products (such as Red Hat Virtualization and Oracle Linux Virtualization Manager) and about companies using oVirt. I could just go googling and guessing by e-mail traffic on oVirt users list but I want to try a different approach this year. So, if you are shipping an oVirt downstream or if you're using oVirt and you'd like to get the company nominated during the community reports please let me know off-list. Also I'd like to remind that oVirt site has a section dedicated to user stories, if you want to share yours you can either push it to https://github.com/oVirt/ovirt-site or get in touch with me off-list to get help getting your story published. Thanks, -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://www.redhat.com/> *Red Hat respects your work life balance. Therefore there is no need to answer this email out of your office hours.*

About the cluster compatibility version
by tommy 30 Jul '21

30 Jul '21

From the document: oVirt clusters have a compatibility version. The cluster compatibility version indicates the features of oVirt supported by all of the hosts in the cluster. The cluster compatibility is set according to the version of the least capable host operating system in the cluster. I didn't quite understand the last sentence. How can the version of the cluster be determined based on the operating system version of the host? Should the cluster compatibility version be determined based on the version of the oVirt engine on the host?

About the oVirt Document
by tommy 30 Jul '21

30 Jul '21

Why don't the documents displayed on the site match the specific software version? Different versions have different functions, but the document does not show the version number, which is very bad for learning.
