Hi There !

I tried to set up a virtual server opn XenServer 5 in my XenCenter.
But it does not start, saying:

HVM is required for this operation.

I did everything as they say in there video exept: I am using the local hard disk.
I select "Windows Server 2003" from the Templates and use an image from "Windows Server 2003 R2 Standard" (BX2SFPP_DE.iso)

Does anyone have an idea ...

Thank you for every tip.

One of two things:

1.  You do not have the virtualization option enabled in the computer's BIOS
2.  Your processors do not support virtualization
XenServer requires virtualization support from the CPU.  Intel's technology is called VT.  AMD's version is AMD-V.  This is an option you can enable or disable in BIOS.  What make and model server are you installing on?

Well, VT should work, as the guys working at the data center told me, but I am not quite sure.
During installation of XenServer, the program said VT would not be there. I tried again after making sure it is not disabled in the BIOS and I did not see the message the second time I installed XenServer (maybe I clicked it away...)

The CPU is an E8400, which should support VT.
In the BIOS I only found:

Core Multiplex Technology   <Enable>
...
Virtual Appliance (VA)
VA Operation     <Enable>
....

I would expect something with ...VT..., but I have no experience with VT mainboards.
Unfortunately I don't now which mainboard is installed.
It's a rented system (http://www.cs-arena.com/index.php?module=rootserver ->08).
So far the guys where very cleaver. I would not expect them not to know/tell me if the mainboard does not support VT.

It was the mainboard.
Data center had to update BIOS - now VT works :-)))
