I'm running windows 2000 in qemu 0.7.0 with kqemu 0.6.2-1 on i386 debian linux. First thing I tried to do was to run a benchmark program (qemu w/o kqemu vs qemu w/ kqemu). I got strange results, and I also noted that timing didn't seem to be that good, so I re-tried to run the benchmark program, but with the date & clock settings window in the background. This is the result: The more cpu that is used in the virtual cpu, the faster time flies by. For example, when it's nearly idle, time is too slow. If it goes from idle to 100% cpu-use, time flies by at 5x the speed it should. This is true both when I use kqemu and when I don't. This cpu is capable of speedstep, but I have disabled it while doing this test. I think I would get even more weird results if I enabled it. This makes it impossible to run a benchmark and get any useful results out of it. Also, trying to run a game on qemu would be a disaster.
Not necessarily, Age of Empires 2 runs quite well under Qemu + Win98SE (on an Athlon 2600+, host: Debian Linux, kernel 2.6.9).
However, running normal programs aren't any problem. Except that I have to be very quick when changing resolution in w2k (it should wait 15s, now time flies away and those 15 becomes 2s :)). Before compiling qemu 0.7.0 with kqemu 0.6.2-1, I ran qemu 0.6.something, taken from the debian testing repository, and it had the same problem. Regards, Alexander Toresson PS. I'm susprised nobody has seen this problem before. Is it just me who experience it?
Although I use Visual Studio 5 and Age of Empires 2 inside Qemu (with Win98SE and Win2k), I never noticed such problems, and the Windows clock always seemed quite right (and VC++ stresses the CPU quite a lot!). But admittedly I never ran benchmarks or had a closer look at the guest system time.
