The document describe how to setup default boot kernel for a Linux VM guest without booting the VM guest.
The illustration below is tangible only when:
1. The /boot file system of the target VM guest is built on partition directly.
2. The file system type of /boot partition of the target VM guest is known by dom0, e.g. ext2/3/4, ocfs2.
The point is using kpartx to create device maps of the boot disk of VM guest on dom0, then mount the device-mapper device of /boot partition r/w.
