Sending code around as html does not really help, especially since i
guess that you have a formatting problem with your bootloader
configuration.
My guess is that you want to "append" to the APPEND line and not create
a new line behind it. You might want to add a completely new entry for
that.
LABEL jailhouse
MENU LABEL jailhouse kernel
LINUX /boot/Image-jailhouse
INITRD /boot/initrd-jailhouse
APPEND ${cbootargs} quiet mem=7808M vmalloc=512M
This would be an example entry expecting two new files
"Image-jailhouse" and "initrd-jailhouse", making sure you do not have
to overwrite the previously working kernel.
But as long as you do not see the change in /proc/cmdline you have a
boot configuration issue not related to jailhouse at all. Consult the
documentation of your distro or the booloader used by it.
