Android Studio Emulator Error: KVM is required to run this AVD. /dev/kvm is not found. (Ubuntu)

KVM is required to run this AVD.
/dev/kvm is not found.

Enable VT-x in your BIOS security settings, ensure that your Linux distro has working KVM module.

Suggestion post::
Use the below command to check whether the KVM is installed in the machine or not,

kvm-ok
Output:

INFO: /dev/kvm exists
KVM acceleration can be used
Output like the below means,

INFO: Your CPU does not support KVM extensions
KVM acceleration can NOT be used
In this scenario need to install KVM using the below command,

sudo apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils
Hope this helps.
