docker : When creating a machine VT-X/AMD disabled yet

[Andy_Kwok]

I'm going through this tutorial (cannot put the web link for now)

When trying to create a virtualbox with the command below

Code: Select all

 docker-machine create -d virtualbox dev;

I have the following error

Error creating machine : Error in driver during machine creation. This computer doesn't have VT-X/AMD enabled. Enabling it in the BIOS is mandatory

Why o' why I have this ugly error?

(Addendum: I'm running ubuntu box on a virtual box. The VT VT-X/AMD is enabled in the bios and in the virtualbox.)

Reading here and there, it seems to be a normal behavior because I'm trying to create a virtualbox within a virtualbox (I will put the link tomorrow)

What command should I use instead of docker-machine ?

Any insights are more than welcomed ...

Thanks!

Yep. That'd do it!

VT-x does not come through the first Virtualbox guest to be used in the second guest. You can run nested 32-bit guests that don't require VT-x, which excludes later versions of Windows (probably 8 & later). Any such nested guest will run slow. And nested Virtualbox isn't supported on the forum.
