  You might try to just run 'kvm' as that will run a KVM with (x86) Bios with -enable-kvm being set. It will eventually stop as it has nothing to boot, but you will see if kvm can be used.

Starting with Ubuntu 18.04 and Linux Mint Tara you need to install qemu-kvm

sudo apt install qemu-kvm

Check the ownership of /dev/kvm

ls -al /dev/kvm

Check which users are in the kvm group

grep kvm /etc/group

Output from the above command

kvm:x:some_number:

If there is nothing rightwards of the final :, there are no users in the kvm group.

To add the current user to the kvm group

sudo adduser $USER kvm

which adds the user to the group, and check once again with grep kvm /etc/group.

A restart may be required for the permissions to take effect.

  Never log in as the root user! There's nothing you could do as root, that you can't do with sudo. And if you only need the permissions of a specific group, sg if you belong to it, sudo -g if you don't — sg kvm <path-to-your-android-studio>/bin/studio.sh in this case, given the kvm group has read+write permission on /dev/kvm.
