I think this applies to compilers, not virtual machines... I've never heard of a Perl interpreter written in Perl, the same to Python and Ruby.
Well, actually, there's PyPy, and I'm pretty sure there's a Perl equivalent.
However, I'm not a fan of self-eating languages in general - it strikes me as a language designer's conceit, usually.
Potentially, yes. Althought the best C compiler are all written in C and the best java compiler is written in java.
But a compiler and a virtual machine are two different beasts, agreed, a hybrid between a CPU and an OS.
Now I wonder, what language do CPU designers use to write their microcode? I strongly doubt they use VHDL/Verilog to define, for example, their 'branch prediction' logic.
