bug#44805: Guix System Problem with GNOME Boxes

[Pelian Pur]

To build a virtual machine with GNOME Boxes, I have this problem:
"virtualization extensions are unavailable on your system. Check your
bios settings to enable them."

I had not encountered this problem on other operating systems such as Debian.

I recommend checking the permissions of /dev/kvm, and if the GNOME Boxes
application has permission to access /dev/kvm.

bug#44805: Bug report is not help-guix

Dear,

Please avoid to pollute the Bug Tracker.  Because people doing bug
triage are then unhappy and have to read irrelevant messages with the
bug at hand.

The usual entry point asking for help is help-guix@gnu.org or #guix on
irc.freenode.net.


All the best,
simon

You should add yourself to the ‘kvm’ supplementary-group.

Kind regards,

I added myself to this group using this method `sudo usermod -a -G kvm username`. But the problem is not solved. Did I do this wrong?

Yes.  Remember you're using Guix System, a (relatively) 
declarative operating system.

Read the ‘User Accounts’ section of the Guix manual, edit your 
configuration, reconfigure, and reboot.

in the future, please copy the text instead of taking a screenshot. it
makes it easier for others to copy your code, and uses significantly
less storage.
