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
Had same problem, it worked when you restart the program.
sudo chmod 777 -R /dev/kvm
