Bringing up a windows instance without using kernel and ramdisk images

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

Here is the patch for /usr/share/eucalyptus/gen_kvm_libvirt_xml that ships with Ubuntu 10.04 (Lucid Lynx) 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. If you need the flexibility of launching instances using different kernel/ramdisk combinations, this hack is not for you! view source print? 01 --- /usr/share/eucalyptus/gen_kvm_libvirt_xml 02 +++ gen_kvm_libvirt_xml.modified 03 @@ -75,7 +75,7 @@ 04 our $use_ramdisk = 0; 05 06 # deal with command-line parameters 07 -GetOptions('ramdisk' => sub { $use_ramdisk = 1; }, 08 +GetOptions('ramdisk' => sub { $use_ramdisk = 0; }, 09 'ephemeral' => sub { }, # option ignored 10 ) or exit (1); 11 12 @@ -84,7 +84,6 @@ 13 <name>NAME</name> 14 <os> 15 <type>hvm</type> 16 - <kernel>BASEPATH/kernel</kernel> 17 EOF 18 19 if ( $use_ramdisk ) { 20 @@ -92,7 +91,6 @@ 21 } 22 23 print <<EOF; 24 - <cmdline>root=/dev/sda1 console=ttyS0</cmdline> 25 </os> 26 <features> 27 <acpi/>
