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.

Yes, I start to realise this.
I have switched to Docker, running inside my CI server.
I don’t know of any hypervisor that allows nested virtualization.
In short, I don’t think that has changed (I’m a customer, but I’ve manage/managed multiple types of hypervisors, from Xen to VMWare ESXi to KVM).
