SLES 11 x86_64 on Citirix Xen Server 5.5

[gbatumbya]

I installed, SLES 11 x64 on xen server 5.5 using the sles 11 x64 template.
I installed the xen tools and configured remote configuration.

On connection via vnc to the vm, all i get is a gray screen.

I have tried with both GNOME and KDE, but still gray screen.

Error when using GNOME
