Answer 1

Assuming that you want to apply this change of ownership using the current OS user, use the following:

sudo chown $(whoami) -R /dev/kvm

Answer 2

Try these steps:

Install qemu-kvm like following

sudo apt install qemu-kvm

Add user to kvm group using the following command:

sudo adduser <username> kvm

If you are getting permission denied, try following command

sudo chown <username> /dev/kvm

It worked for me in Ubuntu 18.04

Answer 3

Check nano /etc/group contains a line begins with kvm and ends with your user name. If not then run:

sudo gpasswd -a $USER kvm

Answer 4

I solved the problem running

sudo apt install qemu-kvm
sudo chown username -R /dev/kvm

Answer 5

Simply try this. this was work for me

$ sudo chown username -R /dev/kvm

sometimes you need to run this code also

$ cd Android/Sdk/emulator/lib64/libstdc++
$ mv libstdc++.so.6 libstdc++.so.6.bak
$ ln -s /usr/lib64/libstdc++.so.6
