Lguest: The Simple x86 Hypervisor Lguest allows you to run multiple copies of the same 32-bit kernel: simply modprobe lg, then run Documentation/lguest/lguest to create a new guest. I suggest you try this yourself - lguest is incredibly easy to get up and running. It's also quite useful: I can test-boot kernels with it in less than a second, or about 10x faster than basic qemu, and 100x faster tha
