jailhouse cell linux --help
[...]
--write-params FILE, -w FILE
only parse cell configuration, write out parameters
into the specified file and print required jailhouse
cell commands to boot Linux to the console
It also reports the commands you need to issue on the target. Those
reveal which addresses the images should be loaded to.
Note that I pushed some updates to the next branch that make the gap
between kernel and initrd configurable, and they also shrink it for
ARM64 (because that arch does not do any kernel compression). Maybe
worth a try.
