I just played with -drive if=scsi and -kernel-kqemu in a linux guest and a dd bs=64k from a 5MB file to /dev/null got me more than 25 MB/s! While a similar dd off the emulated ide cdrom drive (I was using a livecd iso, sidux-2007-04.5-200712260120-eros_xmas-kde-lite-i386.iso) only gets me about a tenth of that. Can anyone reproduce this? :) This is the first time I've seen qemu doing more than a few MB/s IO on this box... Btw a FreeBSD (FreeSBIE) guest didn't get nearly as much, tho that may partly be because the image I used was vfat and FreeBSD's msdosfs is not exactly fast. (Or maybe scsi tags weren't enabled or something.) Still surprised... Juergen
