Check the various ways of booting a kernel via pxelinux.cfg file, e.g. by specifying the config file name via the MAC address or the UUID of the guest. Also check whether we can successfully load an alternate kernel via the "loadparm" parameter here and whether the boot menu shows up with "-boot menu=on".
