It didn't. Fixed that and now I can start the non-root cell. Thank you!

You can find a working x86 inmate kernel config in

I'll prepare a pull request to update the documentation.

Although I cannot see any errors in the Jailhouse console anymore, my Linux 
guest still appears to be stuck somewhere.
The console output I get is:
Adding virtual PCI device 00:0c.0 to cell "linux-x86-demo"
Adding virtual PCI device 00:0d.0 to cell "linux-x86-demo"
Adding virtual PCI device 00:0e.0 to cell "linux-x86-demo"
Adding virtual PCI device 00:0f.0 to cell "linux-x86-demo"
Created cell "linux-x86-demo"
Page pool usage after cell creation: mem 375/975, remap 16395/131072
Cell "linux-x86-demo" can be loaded
CPU 2 received SIPI, vector 100
CPU 3 received SIPI, vector 100
Started cell "linux-x86-demo"
CPU 3 received SIPI, vector 9a

I added the JAILHOUSE_CELL_VIRTUAL_CONSOLE_ACTIVE bit to the linux-x86-demo 
cell flags to get kernel message output in /dev/jailhouse in the root cell. 
Is that supposed to be working or do I need to use UART?

At first there was a PIO read access violation at port 87, I went to check 
my root cell config and found the following:
        /* Port I/O: 0080-008f : dma page reg */
        /* PIO_RANGE(0x80, 0x10), */

So I added that exact range (0x80, 0x10) to the linux-x86-demo PIO configs 
and the error disappeared.
Could that be related to the cell being stuck issue?

To ensure it's not related to other missing guest kernel options, I will 
build a kernel with your amd64_defconfig_5.4 
<https://github.com/siemens/jailhouse-images/blob/master/recipes-kernel/linux/files/amd64_defconfig_5.4>
 
and see if I get the same results.
