Yes, just select a standard or smp non-xen kernel. Do you have options when you see the grub loadeer?

It sounds as though you have the XEN hypervisor loaded into your kernel.  You can not use two virtualisation products at the same time.  You will need to reinstall your host OS, without the XEN oprion.

Yes, that's correct.

But you may want to consider installing VMware ESXi instead? (on the bare metal!) for free, as VMware Server 2.0 is now defunct.

ake sure that the hardware on which the ESXi installation is going to be performed is in the VMware HCL before installing ESXi.

HCL link - http://goo.gl/YwWF9

ESXi v4.1 (Free Edition) would be my recommendation. Its a 64-Bit hypervisor and does not require the presence of an operating system.

ESXi v4.1 download link - http://goo.gl/3ccjb

Make sure that Intel VT or AMD-V is enabled on the BIOS before initiating the installation.

You should be able to use yum to download and install a kernel without xen if you don't already have one installed. You may also need the kernel-devel package and the build tools to install vmware server if there are not already pre-built modules for your system.
