Hello Luke,

What you have written concerning cavatools is accurate.  But be advised cavatools is very fast partly because it leverages the host machine’s VM system—which is why it is user mode Linux virtual machine.  If you want to boot Linux you need machine mode emulation, which requires TLB emulation for every memory reference.  Memory references are 30% of instructions; TLB emulation slowdown is very significant.
