Qemu-fast

Computing: Software: qemu: qemu-fast

Summary
qemu-fast is like qemu (and is part of the same package) but runs faster by using part of the actual CPU hardware -- the Memory Management Unit (MMU) -- instead of simulating it entirely in software. (This technique is called "virtualizing", if I understand right.) There is some correspondence between qemu-fast and kqemu, but I haven't figured out what it is. In my testing, qemu-fast was not able to run the same Win98 image which ran well under qemu. (It may be that qemu-fast doesn't work with Win98.)

qemu-fast is included in the qemu distribution.
