Hi there,

I'm trying to use kvm on CentOS 5.4 64-bit to virtualize Windows Server 2003. I've been able to install and start the system using 1GB of memory, however when I try to increase the amount of memory available to the VM to 4GB by editing /etc/libvirt/qemu/windows2003.xml, I get the following message when starting the VM through virt-manager:

---------------------------------
Error starting domain: internal error Domain windows2003 didn't show up

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/engine.py", line 498, in run_domain
    vm.startup()
  File "/usr/share/virt-manager/virtManager/domain.py", line 573, in startup
    self.vm.create()
  File "/usr/lib64/python2.4/site-packages/libvirt.py", line 287, in create
    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: internal error Domain windows2003 didn't show up
---------------------------------

Here is the content of /var/log/libvirt/qemu/windows2003.log :

QEMU PC emulator version 0.9.0, Copyright (c) 2003-2007 Fabrice Bellard
usage: qemu [options] [disk_image]

'disk_image' is a raw hard image image for IDE hard disk 0

Standard options:
-M machine      select emulated machine (-M ? for list)
-fda/-fdb file  use 'file' as floppy disk 0/1 image
-hda/-hdb file  use 'file' as IDE hard disk 0/1 image
blah blah blah
---------------------------------

It looks like qemu is unhappy about the memory parameter.
Here is my config:

Any idea ?
