qemu can afaik. I've also heard about simnow in qemu and
Xen in qemu, although that's not true recursion. And VMware/qemu/
simnow/UML/... will all probably run fine in Xen native guests.
I wouldn't be surprised if UML supported true recursion too.

But then for what do you really need recursion? It might be nice
theory, but in practice it's probably not too relevant. I guess it
was useful long ago for debugging VM itself when mainframes were
really expensive so you couldn't just buy a development machine and
test your VM on raw iron. But that's not really true today anymore.

Ok one weak reason to still use it might be if your test machine takes
too long to reboot. But then Hypervisor hackers are a pretty narrow
target group for features like this.
