[Qemu-devel] About qemu emulation speed (a question) and supported OS

[Alexandre Leclerc <alexandre.leclerc@gmail.com>]

Hi all,

I'm new to qemu and my question is simple and is probably due to my
ignorance. If I compare qemu and vmware, there is a great deal of
emulation speed differences.

- Is it because of what qemu is? (i.e. it is a full emulator of many
platforms, etc. Meaning that vmware is probably only specialised for
x86...)
- If no, is it possible that one day qemu reaches the speed of vmware?

I'm just asking because I'll probably need an emulator for a host
linux guest winxp in few time. This is for a production environment
and to develop in windows (so programming in the vm all day long, so
speed is very important since it impacts productivity.) So I must know
if it is better for me to buy a vmware licence.

By the way, I succesfully installed XPHome on 0.7.2 from the boot CD.
It took 3 about hours for the installation and it is globally slow to
run (host is Mandriva LE 2005, P4 2.4Ghz). If someone is interested in
updating the stat on the web site (supported guest OS). I really did
nothing special. Made an ISO, created qcow hd, FDISK-ed / FORMAT-ed hd
from freedos bood disk.

Best regards.
