With the command you quoted yourself in another message in this thread
(but slightly edited by me):
    egrep -o '(vmx|svm)' /proc/cpuinfo

And by Googling on "vmware" and "kvm" or "nested kvm". I'm not sure what
the current state is of kvm run inside virtualization tools, sorry.

I see. (Maybe it might be easier to run qemu directly, with the -kernel
option, using (a copy of) your Ubuntu 12 vmware image. Ask around on
qemu related forums, lists, etc.)

Again, ask around on qemu related forums or lists, etc.

There's probably a qemu command line option involved. Ask around... (see
above).

You might need to tweak the qemu image you use inside your vmware image.
The vmware image should not be the issue (see another message from me in
this thread).

Hope this helps,
