Windows self replicate? Does that mean my QEMU installation will start backing itself up? This could come in handy. =) In any case, has anyone played with QEMU lately? I currently don't have the guts to install an alpha-stage kernel patch, so I haven't yet tested out KQEMU aka the QEMU accelerator. Any comments on that? (and no, please don't refer me to /., the source of myriad mis-information) Also, how does /proc/cpuinfo get its data? I think the Bogomips number is calculated at boot time, no? How about the CPU speed? I am asking because if I tried booting linux in QEMU under my gentoo box, the Emulated OS reports the exact same data in /proc/cpuinfo compared to the host OS, except for a bogomips number that is slightly slower (IIRC something like 70% of the host OS). I know that bogomips are NOT the best way of measuring performance, but consider the following: From the QEMU website http://fabrice.bellard.free.fr/qemu/ * Without the KQEMU module, the guest OS should run at 10 to 20% of of a native OS on the same computer. * With the module on x86 machines, the guest OS can run at 50% or better. So either bogomips as a way of gauging performance is a lot more broken than I imagined, or Fabrice Bellard significantly underestimated the performance of his own code....
