Unable to Install Vagrant Ansible/Tower box on Ubuntu 18.04

Trying to install Vagarant Ansible/Tower box on Ubuntu 18.04 Amazon EC2 Instance, After downloading Vagarant and Virtual Box I tried to run command " vagrant up --provider=virtualbox" .

The Initial Log Message as follows

==> default: Matching MAC address for NAT networking…
==> default: Checking if box ‘ansible/tower’ is up to date…

But it fails with Error as follows :-1:

Can you please let us know how to resolve this error? Do I need to make any further changes to Ubuntu 18.04 before I run command vagarnt up command? Or is it compatible with Ubuntu 18.04 to run virtual box to access Vagrant Image??

I tried to run Vagarnat Up Command after installing Virtual Box and Ansible Tower Image. I’m getting following error, Even I checked BIOS to see whether I need to enable any virtualization options. I’ve two options which are alredy enabled they are : Intel® Vitualization Technology and Interl ® VT-d Feature, But I don’t see any VT-x. Is it old one one?
