Has anybody actually done this? VirtualBox does not virtualize the VT-x/SVM support of the hardware to the guest OS (nor does any other hypervisor, afaik). The Linux OS running under VirtualBox of the host Windows machine will never detect VT-x/SVM, and so the hardware required by QEMU, kvm, etc. won't be there, right? If so this page will lead some down a cruel dead-end path. Otherwise the details for circumventing the issue need to be given here. -Some random user
I tried setting things up under a virtual box under Win7 64bit with an image of ubuntu 10.04 and even with qemu-kvm nothing was happening. The command was returning instantly despite it claiming "This will take a while". Luckly I ran into this talk page before i wasted any more time trying to debug. I'm going to add a note about this issue on hte page. If it's wrong and I'm simply doing something wrong then good. Otherwise it would be best we don't waste devs' time.
