Dear all,

I installed a vista guest OS on a RHEL5 machine with Geforce 8600GT
video card. I used the native nv driver because nVidia's driver does
not support a xen kernel. The installation went through smoothly.

However, the guest OS ran very slowly. The 'vista performance score'
for video display (which showed as a standard VGA) was 1, and the CPU
performance (I chose to use 2 cores out of 4 of a Q6600 CPU) was 2.1.
The corresponding scores were all above 5 for a dual-booted vista
system on the same machine.

I am not sure how I can improve the performance of this system. This
is the first time I run Xen so I might have missed some really basic
things. Any help will be highly appreciated.
