Hi David,


Currently there are loaders for bzImages and flat binaries only.  Since your
vmlinux is not detected as a bzImage (it's a plain ELF), kvmtool will assume
it's a flat binary (which it isn't) & try that.  Boom!

An ELF loader would be cool though.  (Maybe if I find time...)


Cheers,


Matt
