not really an issue, but wanted to share this so others don't have to go through hours of troubleshooting like i had

tl;dr: don't use docker-desktop on linux.

Docker desktop changes docker config so that all docker commands execute through docker-desktop, and for some reason docker desktop is unable to see /dev/kvm/.
so the solution to this problem when having docker-desktop installed, is to completely remove docker desktop

to completely remove docker-desktop first follow this guide in the docker-desktop docs.
(you might also want to delete ~/.docker, but be careful, this deletes all docker configs and containers as far as i know, so make a backup of it)

now execute these two commands to return the docker context to normal:

docker context ls
docker context use default

now restart and it should be fixed if everything else is configured correctly
