Hi mat,
Again thanks a lot for your replies.
Basically we have to run same installed windows as domu
in xen. According to you if we will run if we
will run same installed windows as domu then it might be that some
applications will not run properly, that is fine. What I am asking is
the method I have described (first create image of windows then install
xen and finally create domu using that image) is possible or not.
Because in creation of domu it ask for the ISO image. Since we can't
create the ISO image of installed windows, we can only create the disk
image of installed windows. The question is that will we be able to
create domu using that disk image?
In case if we are not able to create domu using that disk image. Is
there any other method through which we can run already installed
windows as domu,
considering that we are not installing windows again.
If you will throw some light on it, it will be great for me.
Thanks,
Praveen Kushwaha

No, you should install Windows AGAIN, this time in the Virtual machine.

This is the FIRST step.

That sounds right. And by the way, if you wish to pass the original
Windows installation as a physical disk to your Windows domU, you can do
that too, and it can then be used as to store files - you just don't
start the Windows installation that is on there. If you do things right,
you can probably run most applications you have on the already existing
installation too - but some applications become unhappy when you change
the environment around them, so may not work [also, apps that install
.DLL's into the Windows directory will need to have the relevant DLL's
re-installed on your Guest installatin].
