Android studio can't access /dev/kvm directory. To allow access run

sudo chmod 777 -R /dev/kvm

It will ask for your password. After that restart android studio.

this will remove all restrictions for /dev/kvm for all users on your machine. I'd recommend [Jerin's answer](https://stackoverflow.com/a/51693686/11359707). – ideam May 09 '19 at 21:20

I followed these steps to make it work in Ubuntu 18.04

Step 1: Install qemu-kvm

sudo apt install qemu-kvm

Step 2:

Add user to kvm group using:

sudo adduser <username> kvm

Step 3: If it still showing permission denied:

sudo chown <username> /dev/kvm

I would suggest informing that the user may need to logout and login again after the command "sudo adduser kvm" – LRMAAX Feb 11 '19 at 01:49

No need to give whole permission to the kvm. you can give owner access for the kvm is fine like as follow

sudo chown <username>:<username> /dev/kvm

This is a realistic error message related to permission but mine happened to be the same message when java was not installed and ran the app. Hope this will help if would be my case.
