I installed VirtualBox 4.3.2 in my Azure Virtual Machine, but I can't open a 64 bit VM (Windows Server 2012 R2 64bit).
Virtualbox send a message about not having vt-x support
Can I configure my Azure VM somehow?

2Azure is already a virtual machine! What are you trying to do? – Michael Hampton Jan 28 '15 at 18:48

1Are you trying to do nested virtualization? – joeqwerty Jan 28 '15 at 18:49

1@MichaelHampton Using a VirtualBox VM because a previous machine have a lot of configuration that I don't want to reconfigure ... – Rodrigo Juarez Jan 28 '15 at 18:49

@joeqwerty yep, just trying to run a previous Virtualbox VM in Azure – Rodrigo Juarez Jan 28 '15 at 18:50

What OS is your VM? I think you'd be better off finding a way to migrate it. – john Jan 28 '15 at 18:59

1This is why we have things like ansible, chef, salt, puppet... – Michael Hampton Jan 28 '15 at 19:43

@john Windws Server 2012 R2 both, the host and the guest OS – Rodrigo Juarez Jan 28 '15 at 20:07

With a few exceptions, such as classic VMware on the guest, it's not possible to nest virtualization within virtualization. Although this would be a convenience for you, you'll have to attack it from another angle. Perhaps look into exporting a machine image from Virtualbox and then importing to Azure.
However, I did find somebody doing just what you ask: https://therightjoin.wordpress.com/2014/08/01/run-virtualbox-on-an-azure-virtual-machine/
This may work for 32-bit versions of guests, since those version do not require the hardware virtualization to be enabled (VT-d). I doubt you'll have any success with 64-bit guests.

1I'm pretty sure you can technically run a 64-bit guest OS now as long as VT-d is enabled, via Hyper-V or VirtualBox. The bigger question is if the Azure physical servers have this enabled (perhaps a specific region?). I tried this on a Windows 10 64-bit VM which shows VT-d is not available. So, on the south-central region, this still doesn't seem possible unless MS changes the bios on their host machines. – Corey Sep 05 '16 at 03:57

For those like me, landing here from a search, this has changed: you can do nested virtualization with the new Dv3/Ev3 VMs: https://azure.microsoft.com/en-us/blog/nested-virtualization-in-azure/

1Just a heads up to anyone looking at this. This still won't work with VirtualBox. Hyper-V nested virtualization is fine though – k29 Jun 19 '19 at 19:21

1I was able to install VirtualBox on Ev3 VM and deploy a VM there. It runs very slow (comparing to Hyper-V nested VM), but still - it runs nowadays – Anton Kuryan Jan 15 '20 at 14:34
