cannot run qemu on xubuntu 8,10

Well, I doubt that I will be able to give you much of an answer, but the answers you give me may help the next person that looks here to help you. I have been studying the docs for quemu but don't know enough yet to try it out. I shall be very interested in reading what answers you get.

So, first, what version of Ubuntu are you running on what kind of CPU?
What kind of config do you have for quemu?
What software were you trying to run, and where stored?
Do you happen too now what a "SDL" is? and whether the message comes from quemu or the software you were trying to run?
Have you tried to run anything else under quemu? If so, what were the results?

First, I am running xubuntu 8.10 on a Pentium 4 Hyper Threading enabled. I manually run qemu from the terminal using the command: "qemu.exe -L . -m 128 -hda ReactOS.vmdk", to of course run the OS reactOS in order to get more native support for win32 programs than wine can provide. I know that SDL is the Simple Directmedia Layer, for providing an access layer to the systems media hardware. I am sure the message is from the program, and not the virtual OS, because it comes from the Ubuntu terminal, not the virtual display. I have not tried to run anything else on Qemu.

I manually run qemu from the terminal using the command: "qemu.exe -L . -m 128 -hda ReactOS.vmdk"

Ubuntu DONT use .exe files, you have been installed Qemu for Windows.
To install Qemu for Ubuntu, type and press ENTER:

sudo apt-get install qemu
