I have a couple of test machines which are running the bare-metal hypervisor version of VMWare, simply for the easy multi-boot & snapshotting capability. I then run Windows under VMWare, and now want to run a Linux VirtualBox under Windows (so VMWare -> Win 7 -> VirtualBox -> Ubuntu).
When I launch my Ubuntu box, I get the "VT-x is not available (VERR_VMX_NO_VMX)" error.
So a few questions:
a) is there anyway I can get this nested setup to work (or is it just not supported)?
b) is there any way to detect VT-x not being available before you launch the VM?
c) is there any way to launch the VM without the VT-x extensions enabled?
thanks
