Hi,
I am trying to run the Jailhouse on UltraZed SOM evaluation board with
UltraZed-EG IO Carrier Card provided by AVNET.
I followed the manual document "setup-on-zynqmp-zcu102.md" at
https://github.com/siemens/jailhouse/blob/master/Documentation/setup-on-zynqmp-zcu102.md
I finished the compile of Jailhouse and installed it onto the rootfs.
When I try to enable the Root cell "zynqmp-zcu102.cell", the system just stuck,
console has no response. and no print output at second UART either.
Attached is the log file of the whole starting procedure.
Could anyone give some hint on what I should modify to make it work?
Thank you in advance!

Note that the zcu102 config we have in Jailhouse expects a reservation via the
device tree at 0x80000000 to 0x83fffffff. You likely leave that region in use
and may thus overwrite kernel memory when loading the hypervisor binary.

Hi Jan,
Thank you for your feedback!
I didn't make any reservation in Device tree, just modified the bootargs
'mem=1536M'
Attached is my device tree.
Where and how should I add the reservation for Jailhouse?
Thank you in advance!
Hi Jan,
I added the following reservation in the zynqmp.dtsi
/memreserve/ 0x800000000 0x40000000
and rebuild the system.
It still stuck at the same place (enabling the root cell)
Attached is the modified zynqmp.dtsi.
Is this the right way to add reservation?
Thank you!
Reservation looks good from here (I don't have the board as reference in reach
ATM).
Could it be that your kernel has KVM enabled? That must be off.
