Enable KVM on VMWare Fusion
Stop the virtual machine and open its settings. Under the "Processors &amp; Memory" pane, expand the "Advanced options" section. Check "Enable hypervisor applications in this virtual machine."

You can also manually edit the VM's .vmx file. For example, if your VM is named "Ubuntu", edit Ubuntu.vmwarevm/Ubuntu.vmx (to get into the .vmwarevm in Finder, select Show Package Contents).

Within the .vmx file, add the following line:

vhv.enable = "TRUE"


After doing either of the above, restart the VM and you can use KVM.
