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: Importing base box ‘ansible/tower’… ==\> default: Matching MAC address for NAT networking… ==\> default: Checking if box ‘ansible/tower’ is up to date… ==\> default: Setting the name of the VM: ubuntu\_default\_1564263669954\_17762 ==\> default: Clearing any previously set network interfaces… ==\> default: Preparing network interfaces based on configuration… default: Adapter 1: nat default: Adapter 2: hostonly ==\> default: Forwarding ports… default: 22 (guest) =\> 2222 (host) (adapter 1) ==\> default: Running ‘pre-boot’ VM customizations… ==\> default: Booting VM… But it fails with Error as follows 👎 used by Vagrant (Vagrant::Errors::VBoxManageError) for controlling VirtualBox. The command and stderr is shown below.

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?

Hey there @Kalyan-Alamuru - This is expected. If you wish to use nested virtualization on EC2, you need to use a tier that supports it. As I recall, I think only one of the bare metal instances support nested virtualization. This is why you are getting the error about VT-x not being available.
