Hi, When I tried to execute jailhouse enable sysconfig.cell on x86 platform, the machine crashed later. This happens in QEMU as well. So I dumped the logs in QEMU and found that there was an error when jailhouse accessed port 5658 through PIO. Attached is the detailed log information. By the way, my CPU is i5-9600K.
