Hello Ivan,

The toolstack will load the kernel at this physical address. However,
the start of the guest RAM for Xen 4.7 is 0x40000000 (see
include/public/arch-arm.h). Can you try to use 0x40008000 for the guest

I changed address. It seems the problem is solved because PC is now
40008030 (that is address of "work: b work" i think).

You can figure out the associated instruction with objdump.

By the way, how much RAM did you give to the guest?

I wrote "memory = 32" in cfg file, I think that stands for 32 MB?

Correct, so the end of the RAM bank would be 0x42000000. I am a bit surprised that the toolstack does not complain when trying to load the kernel at 0x80008000.

Can you paste the dump of xl -vvv create... ?
