If you are using Windows XP to run embedded use the vplayer virtual machine rather than qemu. Qemu is slow - not DSL!
Search for Vplayer on these forums to find out what to do.
I searched all forums from the begging and im not showing anything except this post that even mentions vplayer.It is actually VMWare. If you are going to run embedded DSL on your own Windows machine only then VMWare is the way to go. If you end up using it on an USB drive and carry it around then Qemu is better. Qemu is slower than VMWare but tweaking DSL can make it reasonably fast.
