On the professional side, I currently use VMWare under Linux to do win32
development and testing.  It is very convenient to have a portable
(across machines) image of my development workstation.  I also use
different VM images for testing under different environments (OSs and
configurations).  What I don't like about VMWare is that I must load
kernel modules and that it is licensed per (OS,user), not per user, so I
would need to buy another license to use a Windows host.  My machines
are very fluid.  I tend to run things on my laptop, workstation, wife's
machine, client's machines (anywhere there is an open seat), so the
simplicity of qemu compared to VMWare is a huge benefit.  Rebooting to
Knoppix might work, but then I don't have the native tools like Outlook
at the client site, or would require me to reboot my wife's machine
(which is against the Law).

Personally, I would like to use qemu to do distributed processing with
an openmosix guest across a variety of hosts.  I've been excited about
single image clusters since the early 90s and I think qemu could be a
very handy tool in management of them, especially when you consider
running the desktops as peers in the cluster, instead of clients of the

I don't currently need GL/DirectX/high end graphics support, but I can
easily imaging the day that it will be required (for apps that use
complex data displays like 3d charts).  Audio is just a nicety for me
(to test failure beeps in the apps I write).

Speed is very important.  Last time I tried, Knoppix was not what I
would consider usable inside qemu on my dual 2.4 Ghz Xeon with 1 GB RAM.
