I am trying to install KVM in ubuntu 16.04 using following command:

sudo apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils

and getting following error:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package bridge-utils is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'bridge-utils' has no installation candidate

Can anyone help me to install KVM in ubuntu OS?

  • Did you forget to run sudo apt-get update? The package bridge-utils is available for all current releases.

    @ShankarMuthusamy You need to go in your PC BIOS and "Security" section (If my memory is good) and enable the VT-X.
