First thing to check if you modified the configs: jailhouse config check configs/arm64/rpi4.cell Also check if Jailhouse issues any error on the kernel console. Then you may try setting CONFIG_TRACE_ERROR (see [1]) to get a pointer to root of the problem - if it is found by the hypervisor. Without seeing all your changes, it's hard to give more concrete suggestions.
