Hey Guixters !
On my laptop running Guix System, I try to execute a VM from the script
generated by "guix system vm". But I issue the following message :
$ /gnu/store/dxrwz82s34zi33n9h9cpn8sqw5pv4qyz-run-vm.sh
Could not access KVM kernel module: Permission denied
qemu-system-x86_64: failed to initialize kvm: Permission denied
I already add builders to the kvm group as stated in /etc/group :
kvm:x:984:guixbuilder01,guixbuilder02,guixbuilder03,guixbuilder04,guixb
uilder05,guixbuilder06,guixbuilder07,guixbuilder08,guixbuilder09,guixbu
ilder10
guixbuild:x:30000:guixbuilder01,guixbuilder02,guixbuilder03,guixbuilder
04,guixbuilder05,guixbuilder06,guixbuilder07,guixbuilder08,guixbuilder0
9,guixbuilder10
What do I miss ? :/
Cheers,
Jérémy

Are you part of the "kvm" group yourself?

Hi Mathiue !
I tried to add myself to the group using :
$ sudo usermod -a -G kvm jeko
Then re-executing the vm script returned the same error.

Just in case: did you logout and login afterwards?
Group attributions need that to become effective.

Hi Sergiu!
That's becoming embarrassing... I rebooted instead of logged out and I
might have lost the group attribution doing so.
Now the VM is running.
Sorry for bothering you with this.
Cheers,
Jérémy !

Hello,
Groups need to be specified in the config.scm file.
You need to edit it, and under "(user-account", find or create the
entry "(supplementary-groups" containing a list of strings.
I have something like this:
(user-account
(name ...)
(comment ...)
(group ...)
(home-directory ...)
(supplementary-groups
'("wheel" "netdev" "audio" "video" ... "libvirt"
"kvm")))
Reconfigure (and possibly reboot) and it will be better :)
