Make sure that it gets interpreted correctly. I suggest always using full paths, due to the fact that libvirt itself is running the VM from a separate daemon which might interpret it differently.

Otherwise libvirt simply passes the path to the kernel image to qemu and doesn't interpret it in any way so from there I'd suggest contacting the qemu mailing list.
