I want to use Docker on a machine that has VT-x disabled (and cannot be enabled). Is this possible?
I'm using Boot2Docker on Windows 7 x64, there's no mention of requirements there, or in the Docker instructions either.
I get this output from Boot2Docker start:

Is it possible, or is there a workaround with VirtualBox settings that can make it work?
No it is not possible. I'm stuck with a similar situation with a Q8200 core 2 duo. Doesn't support VT-x which flat out means no 64 bit virtual machines. Doesn't matter which stack.
