After several days of problems, I finally got Xen 3.0.1 set up in Ubuntu Breezy with the 2.6.12 kernel on a VT-enabled system with an Intel 930 processor and 2GB of memory.

I have been able to install an unmodified guest without any issues other than performance. The guest runs extremely slowly and the mouse and keyboard are all but useless because of the extreme lag. I've tried multiple viewers (vncviewer 3.3, 4.0, and tightvnc), as well as low color depths. I am currently using a file-backed image file, as was recommended in the user's manual, but I don't know of any other item that could be causing such poor performance. I don't see anything about this in the archives and am open to any suggestions
