Xen devel - Mar 2007 - Effect of installing Xen on VT enabled machine

Hi,

 

           I have a  VT enabled machine on which windows xp has been
installed. Now I want to install xen on this VT enabled machine on which
windows xp is already. 

           Is there will be any effect on windows xp after installing
xen on it. If there will be any effect what will be those. If anyone
will have any information please reply, it will be grate for me.

 

   

Thanks,

Praveen Kushwaha

Well, you won''t (successfully) be able to "install Xen on
Windows".

If you want to convert your machine to running Xen, you''ll have to also
install Linux, which will be your "host operating system".

So let''s presume that you have a free drive to install Linux on and you
do this, you will then have to set Linux to be your primary boot, instal
Xen on it (which is relatively easy if you go with one of the Linux''s
that have Xen included from the beginning). 

Now you have Xen + Linux on the machine - and you could, in theory,
start your Windows as a virtual machine (aka guest or DomU) on that
machine. However, the hardwar that Windows sees will be different from
what the real hardware is, so drivers for hard-disk, network, graphics,
sound etc, would have to be re-installed. It''s very likely that the
Windows you have on the machine at the moment would not boot with the
"new hardware". 

It''s probably better to leave the machine in a dual-boot mode, where
you
have Linux and Windows installed in parallel, and then install Windows
AGAIN for use with Xen. That way, you don''t get any hardware problems.
The best way to do this would be to use a physical device (partition) as
your Windows install destination. That way, you could let your regular
"hardware" windows installation share documents by also mounting this
same partition.

Hi mat,
              Thanks a lot for the reply. 
              But I have one more confusion. Suppose in my machine there
is more than one partition. In one partition windows is installed. Now I
want to install xen on it, I will install linux on different partition
and then will install xen in it(on linux). In that case, will there be
any effect on the windows which is in different partition. If there will
be any effect, then to run that windows as a domu, will we have to
install it again?
Please give me your ideas.      

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.

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

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].

Hi.

I think you can keep windows but I would do following procedure. I
would shrink win partition and move it in the back of the disk. On the
free space in the front of the disk I would install xen and then point
the domU on that win partition.

Enterprise version of xen does this automatically. Anyway, I tried the
enterprise version today on IBM x3650 and it is greate.

Have a good day.

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

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].

It MAY work to make a duplicate of the installed windows. The only
problem with that method is that Windows don''t like it when ALL the
drivers that it thinks is going to work DO NOT work, because ALL the
hardware in the system is different. Even changing a single component in
Windows can cause big problems... 

But if you want to try this, fine - just don''t come complaining if it
doesn''t work.

Hi Mat,
         That a lot again for prompt reply. 
         That is fine, windows will not run properly using this method.
It''s ok.
           
         But is there any other method through which we can run the
already installed windows as domu without reinstalling it?
         And also is there way to create ISO image of already installed
windows?


Thanks,
Praveen Kushwaha

Hello,

	I want also solve such problem. 

	As far as I have heard from my colleague (but not tested by self),
there is the possibility how to change the HW configuration in windows if
You want to transfer it to the new platform - You have to first boot on the
old HW configuration where it works, deinstall all devices in the windows
installation, transfer the hdd to the new configuration and then boot with
the new configuration under the new hardware IN SAFE MODE and repair the
current HW of the computer according to the current HW configuration - force
windows to recognize the new HW and install the drivers for it. This could
help in this case too...

	So - this could be the solution for You. But WITHOUT WARRANTY - I do
not have any idea what the windows make if You start to deinstall the
running devices - maybe it is no problem, maybe it has to be in the correct
order, maybe the problem is especially with the motherboard related and such
low-level system devices and you do not have to deinstall anything more - so
this I would try as first do deinstall. I know this really helped to
transfer Windows to new hardware - without doing it the start of Windows
always ended with bluescreen, if some devices were uninstalled before the
transfer to new HW, the system has started and recognized the new hardware.

I would like to test also following procedure - this is especially
interesting for me, I want to have the possibility to have 2 HW
configurations (1 if booted directly as stand alone, 1 if booted under Xen
as DomU):
1. create new hardware profile in windows installation (named "Boot from
Xen", or similary)
2. boot the windows directly again but under this new hardware profile
3. go to the HW manager and set to all devices, which are clear they will be
different, that this device will be not used in current HW Profile
4. Reboot in linux, create the domU for windows accessing the physical disc
with your M$ Windows installation
5. Start the Windows domU and select the previously created new HW profile
and start the DomU in safe mode
6. Hope this could work and be configured / new HW recognized
7. Hope if You boot again directly with the original HW profile, this will
still work...

There is some non-zero chance this could work - but I do not have courage to
try it with my working machine and have no time now to install some test
one...

If You try it, let us know about the results ;-)

	Good luck, Archie.

Hi Mat,
         That a lot again for prompt reply. 
         That is fine, windows will not run properly using this method.
It''s ok.
           
         But is there any other method through which we can run the
already installed windows as domu without reinstalling it?
         And also is there way to create ISO image of already installed
windows?


Thanks,
Praveen Kushwaha

It MAY work to make a duplicate of the installed windows. The only
problem with that method is that Windows don''t like it when ALL the
drivers that it thinks is going to work DO NOT work, because ALL the
hardware in the system is different. Even changing a single component in
Windows can cause big problems... 

But if you want to try this, fine - just don''t come complaining if it
doesn''t work.

To install Xen you''ll need to have an existing Linux install to act as
the
Xen "domain 0".  Do you have that?

VT is just a processor feature which Xen can switch on whilst running if it 
wants it; it won''t affect any installed software or your computer, and
will
be switched off again when you reboot (until you run Xen again, or some other 
software which uses VT).

Btw, it''s better to post questions that don''t involve code or
bug reports to
the xen-users list only.

HTH,
Mark

Moin,

my experiences for exchanging windows xp installations between xen/baremetal
using an AMD with SVM:


a) installing windows in xen, booting baremetal later
I offered the whole disc to xen and installed win to a primary partition.
Pressed
F5 on installscreen, selected ''standard pc''. Created
hardware-profiles. Could not
boot up that installation on baremetal later.

b) installing windows baremetal, booting on xen later
Installed to a primary partition. Did not select ''standard
pc''.  Created
hardware-profiles. Running the installation under xen later on works. Reboots of
xen do not work out properly, this is fixed when the baremetal-installation is
done pressing F5 on installscreen and ''standard pc'' is
selected.


At least i can keep only one win-installation on my disc that way.

Christian

Hi mat,
              Sorry for interrupting you.
		  Actually I have investigated a method for runing an
already installed windows as domu. There is a tool sysprep.exe provided
by windows which creats the image of windows with all the
configurations. Do you know about this tool? Since it creates image with
all the configurations therefore this image is used as intallation
image. 
Therefore my considerations is that we can provide that image into
creation of domu. By this way we can make run already operationl windows
as domu.

What is your opnion? 

You can find about sysprep.exe tool at following links
