I think there is no problem with the debug console configuration I set up.
Please refer to:
.debug_console = {
.address = 0x1004b800,
.size = 0x400,
.type = JAILHOUSE_CON_TYPE_SCIFA,
.flags = JAILHOUSE_CON_ACCESS_MMIO |
JAILHOUSE_CON_REGDIST_4,
},

I turned off KVM as you said but the problem still exists.

I would also like to add:
I refer to this post and added mov and ret modifications to entry.S to
output jailhouse is opening.
However, when using the command jailhouse cell list later, I also
encountered the problem of the serial port being stuck.

So is this way of modifying entry.S the correct way?
I can not comment on that, I'm not into that issue. If it works for you
for the moment to do further evaluation - great! You can of course
contact the original authors of the workaround.
Thanks,
Ralf
