If you want to debug the UART output of Jailhouse without crashing your system every time: Take one of the configured cores offline (echo 0 > /sys/devices/system/cpu/cpu1/online) before calling jailhouse enable. That will make the hypervisor fail gracefully with -EINVAL, but you will see messages of it trying to enable the remaining CPUs - provided we do not crash even earlier in the setup.
