xen +Suse 10.0

I installed Xen when I installed Suse 10.0 on two machines, an athlon 64-bit desktop and and P4 laptop. When I boot into the Xen kernel, I have two problems. 1. It cannot find the Nvidia driver. I have to go to xorg.conf and change the "nvidia" to "nv" to get it to go into X. This is on both machines. Default kernal boot is fine. 2. When I goto Yast, Software, and the Virtual Machine Installation (XEN), it comes up with not enought memory to install 40 MB free. I check, there is 196 meg used from 1 gig. This is on both machines. So How do I fix this? Art
