Linux How To Add User To Additional Group

sudo usermod -a -G groupname username

It's really simple like above, the -a is for append so that you are not changing their main group, but adding them to another additonal group.  Just change "groupname" to your group and "username" to the user you want to be added to "groupname".

A common task these days is getting your user access to kvm for virtualization so the KVM/QEMU process doesn't have to run as root.

An example of adding a user to the kvm group:

sudo usermod -a -G kvm username

For KVM you'd also have to add access to /dev/kvm:

chown root.kvm /dev/kvm

How can you apply your new group(s) without logging off?

exec su -l $USER

You could also just use this:

su - yourusername

The above will only apply in the current shell/terminal
