Nested virtualization

Has anyone successfully gotten vmware to run under kvm?
What does your config look like?

Using the following command ESXi 4.0 is failing to boot. It hangs during the kernel startup I believe

qemu-kvm -m 1024 -smp 1 -name esxi -no-reboot -boot d -drive file=/var/lib/libvirt/images/esxi.img,if=ide,index=0,format=raw -drive file=/home/bk/Downloads/VMware-VMvisor-Installer-4.0.0.Update01-208167.x86_64.iso,if=ide,media=cdrom,index=2 -enable-nesting

This is running on an AMD phenom2 550 chip, Virtualization is enabled in the BIOS as well.
I’ve tried multiple -cpu options and have been unable to get past the current stage.

qemu-kvm --version
QEMU PC emulator version 0.11.0 (qemu-kvm-0.11.0), Copyright © 2003-2008 Fabrice Bellard

Has anyone on the list toyed arond with nested virtualization? Any knee jerks, quesitons, thoughts, comments or otherwise are very much appreciated.

Thanks!
