To fix the above I have followed the link
https://bbs.csdn.net/topics/615205697 and changed as per instruction,
even I followed the earlier build from this link only. but I was not
able to build jailhouse-image.
Ok, perfect.
DTC_INCLUDE += /usr/src/linux-headers-5.4.0-1069-raspi/include added
in the file -->/usr/src/linux-headers-5.4.0-1011-raspi/scripts/Makefile.lib

Yeah, you need to load the jailhouse module first:
insmod drivers/jailhouse.ko
or
modprobe jailhouse
Thanks

Keep calm, I'm still trying to figure out where the problem exactly is.
Now I know the line of code, where the exception exactly happens. It's
in hypervisor/arch/arm-common/psci.c:39
ldr x2, [x20] <- Here we likely load ctx->regs[2], and the only variant
how this could fail is that ctx points to somewhere. Here we're inside
the routine psci_emulate_cpu_on, which shouldn't even be called when
enabling the hypervisor. I don't know yet what could be the issue.
Before we keep on debugging: I saw that you use Jailhouse v0.12.
Could you please switch to the master and/or next branch of jailhouse,
and see if the error still occurs there?
Thanks,
Ralf
