When I try to run an AVD, I get this erros:
/dev/kvm device permission denied
Yeah, I know, I don’t have the permission to access
/dev/kvm, I know that I can “solve” it by changing the
/dev/kvm permission to my user, and set my user to kvm group, it is working but when I restart my user session, the
/dev/kvm permission return to root user and root group, and I need to set the permission to my group again and again…
How to set this permission and prevent that when I reboot my computer my permission are not changed anymore?
SO: Ubuntu 18.04.01
This command should help you:
sudo setfacl -m u:$USER:rwx /dev/kvm
Using it you will grant to current user rwx permissions to /dev/kvm. Or just replace $USER to any user you need.
As mentioned in setfacl manpages “This utility sets Access Control Lists (ACLs) of files and directories.” It’s a little bit different from chmod and chown. Using it you can grant required permissions to specific user. It’s a bit more powerful tool and much more fine-grained. If you want to dive deeper, read about Access Control Lists. For example, in ubuntu docs: https://help.ubuntu.com/community/FilePermissionsACLs
