[Xen-users] Problemes about Windows virtualization (memory, CPU)

[julien collas <jul.collas@xxxxxxxxx>]

Hello,

I have some questions about Windows virtuzalisation on XEN. I currently 
ran some test on Windows' VM (Server 2003 mostly) for my job.
But I can't make some of my expectations which could be useful for my 
prod environment.
Here are my questions:
- Is it possible to have more than 2048Mo of memory per Windows VM with 
a 32bits CPU ?
- Is it possible to have multiple CPU under a virtual Windows ?

During my tests, I couldn't make works the VM with more than 2048Mo 
(while I got 5Go memory in my domU).
For the Multiple CPU on Windows, if I set acpi and/or apic to 1 my 
windows VM freeze when booting it (with vcpus and cpu set properly).
If I doesn't set these options during the installation and I set them 
after, it doesn't change anything.
You may have some ideas ..

My test machine is a bi-xeon E5410 , with 10Go memory , Debian Etch, xen 
i386 2.6.18.6, xen 3.0.3.1. (Only Debian packages)
I have one other question about converting a VMware Windows image to 
XEN. I read this article 
:http://ian.blenke.com/vmware/vmdk/xen/hvm/qemu, but, when I boot the 
final image, it doesn't work, I've got the famous blue screen.
Any ideas ?

Thanks a lot for your answers.

Regards
