QEMU/KVM: Can't access '/var/lib/sss/db/config.ldb', probably SSSD isn't configured

Support Virtualization

Morning,

Just completed installing QEMU/KVM following [How to] Setting up QEMU/KVM with virt-manager. I’m currently having one problem to complete the guide. I get this message when trying step 3.3:

sudo usermod -a -G libvirt $(whoami)                                                                                                                       
[sss_cache] [sss_tool_confdb_init] (0x0010): Can't access '/var/lib/sss/db/config.ldb', probably SSSD isn't configured
Can't find configuration db, was SSSD configured and run?

I’m not familiar with SSSD (I read the man page), can any either link me to a guide or show me basically what to do to complete this portion of 3.3 or should I even use or need it?

Thanks!…

That is not the command that was posted there.

what was posted there is this:

sudo usermod -G libvirt -a `whoami`

The (obvious) purpose of the command is to add the current user to the group.

… the result of which can be verified by:

groups

the result should contain the gropup “libvirt”

Have you just tried to type your user manually instead of relying on scriptlets and variables (which is not defined, obviously)?

sudo usermod -G libvirt -a MYUSERNAME

By the way i just corrected an error in this guide… it started with -Syy unstead of -Syu, which can lead to disaster, potentially. Do not get used to do -Sy (without u)

p.s. i would also avoid evaluation expressions in oneliners as a novice user. It can be a source of different problems and mistakes. Just open another terminal and evaluate the expression there, see if the result looks good and paste it in the first script. There is a reason why paste is a middle click in linux, and select is copy.

[teo@teo-lenovo-v15 ~]$ whoami
teo
[teo@teo-lenovo-v15 ~]$ sudo usermod -G libvirt -a teo
............

Was it hard? It is not even necessary since the logged in user is written in the terminal prompt :slight_smile:

That guide is outdated, and now wrong.

I would attempt to undo everything you have done.

You most likely just want to:

sudo pacman -S qemu-desktop

This is more or less the qemu-full meta package, but with a lot more added added that you want to run VMs locally (with a GUI guest desktop). With all sorta of extra packages like SPICE for dynamically resizing desktops, and all sorts of goodies.

A lot of this comes setup for you. And you shouldn’t have to even touch groups.

Most of those steps in that tutorial are moot, or just not work anymore. Also, always check the Arch wiki for more niche stuff like this.

(Plus, I don’t even have sssd installed. And I virtualise everything!)

Thanks for you rapid responses. I should have checked this first before posting, but I checked my account on cockpit and it does show I was added to the group.

I’ve read the Description using man and SSSD Introduction on the website. I’m a BIG fan on securty and I am working on a FreeIPA Server. This sssd brings up another question:

  1. What is the connection with SSSD when running the said command and giving me this message? The sssd.service is disabled,

  2. Was this installed by default or how did it get installed?

UPDATE: Disregard this post, the solution answered the problem.

Thanks, I will just reinstall KDE Manjaro. It was just yesterday when I installed it anyway.

This is my preference as well. My goal is a Software Development / Workstation to manage everything inside VMs. And leave the Manjaro Host close as possible to its initial install and use admin tools.

I actually do the same. My big VMs are: one for work (lot of vscode and cloud APIs), and one for play (near native gaming performance in Windows) using GPU pass-through.

It gives you many options on how you want to store/backup/snapshot them too. I can even move images to my laptop and back, by sending only the differences.

So many cool things. :nerd_face:

And i have to roll a Win10 because of work and stupid microsoft cloud stuff. :nauseated_face: :face_vomiting:

Really? I had an Azure/Entra job earlier last into earlier this year. I was able to do everything in Linux. A lot through of it were fairly well maintained AURs. From pwsh to Azure Storage Explorer! MS actually has a bunch a Linux fan-boys/girls working over there!

For the life of me, i could not make the office 365 work under linux. The problem was, we have some complicated files that their own web apps cannot display im browser, so we have to use the windows binaries (word excel and co). Didn’t try wine but i doubt it would have worked (o365 is not listed on the wine database).
Life would be so much easier if the cloud apps in browser just worked correctly, but no. That is microsoft. Today we just discovered there are differences in the available menus between the iphone and android apps for sharepoint (wtf?). Why they bother with apps if at the end everybody will still have to use the browser? And they have 3 Apps that do mostly the same thing, but not exactly. O365, Onedrive, Sharepoint. From one of them one could copy a file on the cloud, from the other one could delete. But one cannot MOVE (which is copy+delete). For this purpose you need a 4 App - the web browser, and then you get the full menu.
It is just ridiculous. But it is work. I will use what the boss says. But at home i am the boss. So the windows infection stays only in the VM.

I hear that, I want linux to rule the world of computing!….

Same here, no barebone Windows OS in my shop.

I found how I installed it. It was an option I selected foolishly during the install of cockpit. :face_with_open_eyes_and_hand_over_mouth: Ooops!

It already does in areas that count.

Random published statistics can sometimes be taken with the proverbial grain of salt; however, the overall trend is encouraging:
