Hmmmmm .... OK, I was/am using 32-bit WinXP, maybe that's part of the 
problem. I eventually killed this process after 5+ hrs w/ no visible 
progress & tried again w/ qemu-system-i386 & the rest of the command 
line args, still (apparently) nogo, killed it after about 1 hr., no 
visible progress. I never saw *any* GUI pop up in either case. I'm a bit 
confused here, I thought the qemu executable needed to match the host as 
much as possible, that's why I tried the x86_64 qemu 1st. I think I am 
(partly) confused on that point because I have an older qemu 
(0.13.0-1.fc14) running elsewhere (FC14 64-bit boxen) w/ CentOS 5 & XP 
VM's which run (mostly) OK. Those installs have a plain qemu executable, 
as well as about 20 other specifically labeled executables (see below 
from 1 of the FC14 boxen). I used the plain qemu to build the 2 VM's 
mentioned previously. The build of qemu-devel built about 2 dozen 
qemu-system-* executables, does that executable need to match the host 
or guest OS ? Also, what FreeBSD version were/are you running qemu on ? 
When you say ages to install XP, is that (many?) hours ? TIA & thx  ....
