Its performance is good enough for real work if the kqemu kernel module is used. I did notice a few strange things. - some basic timing seems to be messed up. sleep blocks for roughly /10 of real time (but not always -- `time sleep ' is more like /7). - date seems to flip between current time and jan 2 2000 without any discernible pattern. - occasionally the display goes blank and you have to click somewhere in the plan9 screen to refresh it. Other oses under qemu do not have these problems. More on installation: To speed up the installation I have tried various tricks (including installing on a memory disk) but nothing made any real difference. I just tried this again: qemu-img create plan9.disk 4G qemu -cdrom plan9.iso -boot d plan9.disk This time I chose fossil+venti. Clearing a 3GB venti arena happens very fast, at a rate of 10+ MBps, but the copydist step took 3:24 hours on a 2.4GHz celeron! I do not see such speed problems with other OSes under qemu.
