Qemu-kvm not present in software installer and new guy questions [Solved]

[AVCESAR]

Hi all,

I am new in MXLinux. I just got a new computer that I will use as a VM server. So I tried to get virt-manager to work but there is no qemu connection.
Apparently I have to install qemu-kvm but it's not in the repositories.

I know about this post:
viewtopic.php?p=673067&hilit=qemu+kvm#p673067

But I don't find the packet.
How can I do? Any idea?

Also, is there a server edition of MXLinux?
What is ddm-mx? An nvidia driver manager only? WHat is it's equivalent for the other dirvers? Ryzen, motherboard...

I am on Distro: MX-21_x64 Wildflower October 20 2021

Ty,

it looks like qemu-kvm for debian 11 (which mx 21 is based on) is a virtual package: https://packages.debian.org/bullseye/qemu-kvm

the debian wiki for kvm suggests installing qemu-system (among other packages): https://wiki.debian.org/KVM

it looks like qemu-system should bring in all of the packages (as dependencies) listed as providing qemu-kvm (qemu-system-{arm,ppc,x86}: https://packages.debian.org/bullseye/qemu-system

also the debian wiki page for qemu in case that might be of help: https://wiki.debian.org/QEMU

note: i haven't upgraded to 21 myself so can't confirm the above. i am just sharing what i could find from the sources listed.

I dont find the qemu-kvm in the packets installer. but the sudo apt-get seems to find it.
Why is that? Am I not supposed to find al available packages in the GUI packets installer?

Also, I already used CLI to install it before but my VM was very unstable, so I wonder if the apt-get did not install a qemu-kvm it was not supposed to.

what output do you get for

Code: Select all

apt show qemu-kvm

?

did you install all of the packages recommended in the wiki pages linked above?

[AVCESAR]

I installed it the first time by following this guide: https://computingforgeeks.com/how-to-in ... on-debian/

But then I had the snapshot MXLinux, so I installed the stable version now. I didn't reinstall qemu-kvm in the new MXlinux system.

So I get:

Code: Select all

$ apt show qemu-kvm
Package: qemu-kvm
State: pas un véritable paquet (virtuel)
N: Impossible de choisir une version candidate du paquet « qemu-kvm » qui n'en n'a pas
N: Impossible de choisir les versions du paquet « qemu-kvm » qui n'est qu'un paquet virtuel
N: Aucun paquet n'a été trouvé

After a retry and by noticing the messages it actually says:

Code: Select all

Note : sélection de « qemu-system-x86 » au lieu de « qemu-kvm »

Which basically means it's selecting qemu-system-x86 instead of kvm-qemu.

[xaol]

are your vm's working correctly for you with what you have installed?

[AVCESAR]

Nope, still having problems:

Code: Select all

Unable to connect to libvirt qemu:///system.

Vérifiez que le démon « libvirtd » est en cours d’exécution.

Libvirt URI is: qemu:///system

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/connection.py", line 922, in _do_open
    self._backend.open(cb, data)
  File "/usr/share/virt-manager/virtinst/connection.py", line 153, in open
    conn = libvirt.openAuth(self._open_uri,
  File "/usr/lib/python3/dist-packages/libvirt.py", line 148, in openAuth
    raise libvirtError('virConnectOpenAuth() failed')
libvirt.libvirtError: Failed to connect socket to '/var/run/libvirt/libvirt-sock': Aucun fichier ou dossier de ce type

Waiting for a final stable solution to put the topic as closed and puting my findings here.

[xaol]

can you check the status of the libvirtd service? on sysv i checked all my services with

Code: Select all

service --status-all

i can see libvirt-guests and libvirtd both listed with [+] to the right. the + is an indication of running services according to

Code: Select all

man service

i checked the status of libvirtd with

Code: Select all

service libvirtd status

i used the same for libvirt-guests just in case.

if you are using systemd,

Code: Select all

systemctl status libvirtd

should hopefully work.

Here is a video on installing and getting QEMU up and running:
https://vid.puffyan.us/watch?v=wxxP39cNJOs 13m long
The guy is using arch but with a little savvy shouldn't be too difficult in MX.
He also explains on getting a win10 iso installed which includes the required virtio ones, including network, user, etc..
I'm still waiting on my new minipc as I want to run a win10 iso in qemu on top of AV-Linux.
Search utube for "Ditch Virtualbox, Get QEMU/Virt Manager" on Mental Outlaw's channel.
There are others of course but this one seemed to be quite thorough. Highly recommended.
