You could be.
Lot's of professionals run IBM's VM under VM for various reasons
including testing new releases.
Plex86 on IA32 would allow one to run a (possibly different)
distribution of Linux as a guest in a protected environment. I could
give you a Linux environment on my Linux machine with no possibility
that you could escape.
I can do that at present with Hercules, a S/370-XA, S/390 and zSeries
emulator, but I need to run mainframe software in it.
If there be ways of improving its performance, many people will find
those advantageous.
If you visit http://user-mode-linux.sourceforge.net/ you will find a
project devoted to the notion of running Linux under Linux. There is no
thought there of emulating any machine's instruction set, though it
does have emulated network devices and disks.
