installing win2k 32 bit with kvm on AMD 64 bit (dual core)

installing win2k 32 bit with kvm on AMD 64 bit (dual core)

[Xu Nakajima]

Hello,
 I have an AMD machine with  3800+ Dual Core Processor

Athlon(tm) processor (x86_64).
FC6 (x86_64) is installed on this machine.

This processor DOES support SVM 
(cat /proc/cpuinfo | grep flags shows a line which
includes "svm").
I had built kvm-7 on that machine.
I had tried , according to kvm howto , the following:


modprobe kvm-amd

/usr/local/kvm/bin/qemu-img create -f qcow vdisk.img
10G

/usr/local/kvm/bin/qemu-system-x86_64 -no-acpi -hda
vdisk.img -cdrom /dev/hdb -boot d -m 384

where in the cdrom there is a win2k installation disk
(for 32 bit)
(and the cdrom is **NOT** mounted).

I get immediately an error: 

the console shows:
Segmentation fault

So my two questions are:
1) is such an installation is supported at all on this

configuration (dual core x86_64 AMD with Win2K 
installation of 32 bit)?

2) is it possible to use the same method when there is
FC6 x86_64 installation DVD in the /dev/hdb (the
-cdrom 
parameter).

Regards,
Xu

The processor tried to execute the clgi instruction and got a general 
protection fault instead.  Are you using a Xen kernel?  If so, please 
try again without Xen.

Yes.

Yes.  I never tried installing from the cdrom, but it should work.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

Hello,

Thanks for your answer.

Indeed , I am trying it with FC6, where the kernel is 
Xen kernel. 

 The thing is that with FC6 , the default installation

has a Xen kernel; Does anyone know if I can run a 
non-xen kernel on it / disable somehow the xen kernel
and work with ordinary kernel?  (sorry, I don't know
much about
Xen and FC kernels).

Or , if I am using Fedora Core distros, 
must I run this installation under  Fedore Core 5 (or
lower)
so it will not have this crash ? 

(Fedora Core 5 and lower does not have 
a Xen kernel by default)

Regards,
Xu

It is easy to use a non-Xen kernel:

1. Check if the kernel is already installed:


    rpm -q kernel

if it outputs something like 'kernel-2.6....' skip to step 3

2. Install the new kernel

    yum -y install kernel

3. Edit /etc/grub.conf to make the new kernel the default:

   - look for a 'default=' line
   - change the number to point at the non-xen kernel (entries
     are numbered from zero)

4. Reboot
