Edit /usr/share/eucalyptus/gen_kvm_libvirt_xml to  remove the lines that add “-kernel” and “-initrd” options in the libvirt.xml.

DISCLAIMER: This patch works  with the windows instances  on Lucid Lynx. This would work as long as all your disk images are bootable and you don’t need the kernel and ramdisk images.
