Support for VT-X for VirtualBox

Posted on October 28, 2014

Hi,

I’m running an Ubuntu 13.10 box (2 Gb RAM, 40 Gb disk) for my CI environment.

I want to use VirtualBox + Vagrant in this environment in order to set some test environment for my applications.

However, whereas my Vagrant files work fine locally, on a MacOS, they fail on the DO droplet.

After some investigation, the VM are correctly created in Virtualbox, but they fail to start because of:

VBoxManage: error: Failed to enable and lock VT-x features. (VERR_VMX_MSR_LOCKING_FAILED)

When looking at other posts like https://www.digitalocean.com/community/tutorials/how-to-install-virtualbox-on-ubuntu-12-10-x64, I see the following comment:

Unfortunately we do not support nested virtualization so it is not possible :( Try disabling VT-x using Virtualbox, that should fix it I believe.

Has this situation changed? Is that possible to run 64-bit machines guests using Virtualbox on DO droplets?

Thanks for any help, Damien.
