Cisco VIRL: KVM acceleration is not available

Visco VIRL sometimes throw the following error stating KVM acceleration is not available on hosts running ESXi.

KVM acceleration is not available

INFO: Your CPU does not support KVM extensions
KVM acceleration can NOT be used

You can also run the kvm-ok command to find the status of KVM accleration.

This is due to a missing setting on ESXi Guest OS and the following parameter needs to be added VM’s .VMX configuration file.

Please make sure the VM is shut down before making the change.

vhv.enable = “TRUE”

You can also add this parameter to /etc/vmware/config of the host, but it is not imperative you should do it.
