Hi mat,
Thanks a lot again for such a prompt reply.
Basically my problem is that. I have a VT enabled machine in
which windows is installed in s different partition. Now I install xen
in different partiton (first linux and then xen). Now I want to run that
already installed windows in domu on xen. According to you hardware is
changed for windows now so it will be difficult to run.
Then what other method is
1. First create an image of installed windows
2. Now install xen on machine (first linux then xen)
3. Now create domU for windows using the image file(Give the path image
file which is on disk in creation of domu).
Is this process right for runing the already operational windows as
domu.
Please confirm me. Is there any other method for running already
operational windows as domu on xen. If there is please let me know.
Basically I have to run already operational window on xen.
Thanks,
Praveen Kushwaha

There will not be any effect on the Windows that is already installed as
such - but running that as a guest within Xen will possibly cause
problems (I think there's a feature called "Hardware profiles" in
Windows that COULD be used to fix the fact that the hardware "appears to
change completely", but I'm not at all confident that Windows will
actually cope with this)
It's notoriously difficult to take a hard-disk with (any modern versions
of) Windows and move it to another machine without re-installing
Windows. Running Windows as a guest in a virtual machine is essentially
the same as moving the hard-disk, because ALL of the hardware will be
different - chipset, hard-disk interface, network, graphics,
usb-devices, etc, etc.
So I suggest that you install another copy of Windows using Xen (then
Windows will detect the correct devices). If you install on a physical
partition, then Windows running on the hardware could be used to access
the same data as the virtual machine, so your documents can be accessed
from both the virtual and the real windows setups.
