In that case i would suggest trying a more recent kernel. Something in the 4.14 or 4.19 range, if available for that board.

Re: Jailhouse demo not working on BananaPi BPI-M1
Hi Dan,
you could try an image created with
https://github.com/siemens/jailhouse-images
That will give you a reference image that is well tested and might not
have the issue you ran into.
Does the problem appear every time or just sometimes? Might be a race
in the cpu offlining.

Jailhouse demo not working on BananaPi BPI-M1
Hello,
I tried to run jailhouse on a BananaPi BPI-M1 as described on the Jailhouse
Documentation [1].
I configured the u-boot parameters as described(with mem=932M vmalloc=512M),
and did all the steps described in [1] and all is fine until I run the command
$ jailhouse cell create ~/jailhouse/configs/arm/bannapi-freertos-demo.cell
After running the command there is some logging on the screen [2] and the
console freezes.
I tried to do it all over again, but same thing happens.
