I think the main problem is that any VM written in a higher-level language will be too slow for practical use.
When you combine their deeply analysing and heavily optimising compilers, with their freeing the programmer from so much of the low-level housekeeping like memory management, using almost any of them to create a VM interpreter would be a win in terms of productivity.
It may be that you would want to hand code the dispatch loops and JIT compilers in C or even assembler--maybe--to squeeze out the final ounce of performance, but you retain those generated by the compiler/hll for debug and benchmark purposes.
Most of us here recognise the benefits of using high(er) level languages with in-built memory management and revel in the freedoms that gives us. It seems silly to eshew those benefits for writing the vast majority of the infrastructure and kernel of a VM. Better to write in a HLL for reliability and productivity and reserve C for tuning the performance critical parts.
