Unable to run xen

Description

When booting xen (actualy a Knoppix/XEN live CD), and depending on the config of the virtual machine I got these situations:

1- If VT-x is dehactivated (whatever the option selected for the Nested Paging), XEN stops at "reliquishing the VGA console", and is not able of starting the Dom0.

2- If VT-x is activated, XEN is not starting at all! With VirtualBox 2.0.6, I was able to run XEN with VT-x activated, and after, Dom0 start with no problem.

PS: Does VirtualBox emulates the VT-x instructions to the guest OS? Although my hardware supports VT-x, XEN reports that the CPU is not VT-x compatible!

I'm running now the the live cd[1] from the book "Running Xen"[2] without problems. It boots fine and I can create any of the domU images that come included with the cd.

What I can't do is boot a fresh CentOS 5.2 install with a xen kernel, it hangs when trying to load the kernel. So, VirtualBox is indeed capable of running nested hardware virtualization, but it seems it can't in some cases.
