When you add a kernel to Walrus, you bundle the kernel file,
upload the file to a bucket in Walrus that you name, and then
register the kernel with Eucalyptus.
To add a kernel to Walrus:
Example
For example:
euca-bundle-image -i euca-fedora-10-x86_64/xen-kernel/vmlinuz-2.6.27.21-0.1-xen --kernel true
...
Generating manifest /tmp/vmlinuz-2.6.27.21-0.1-xen.manifest.xml
euca-upload-bundle -b example_kernel_bucket -m /tmp/vmlinuz-2.6.27.21-0.1-xen.manifest.xml
...
Uploaded image as example_kernel_bucket/vmlinuz-2.6.27.21-0.1-xen.manifest.xml
euca-register example_kernel_bucket/vmlinuz-2.6.27.21-0.1-xen.manifest.xml
IMAGE eki-XXXXXXXX
Where the returned value eki-XXXXXXXX is the
unique ID of the registered kernel image.
