Could you also attach the host dmesg please?

xl create -vvv, dmesg and xl dmesg output attached.

Nevermind. I can reproduce it. The interesting thing is that initially I had
this in my guest config:


and the output of the tools told me:
Memory: 1048576kB End of RAM: 0x20000 (PFN) Delta: 524288kB, PCI start: 
524288kB (0x20000 PFN), Balloon 1048576kB

.. and then it added that 1G to the end:

libxl_x86.c:201:e820_sanitize: :  [100000 -> 160000] RAM

and the guest booted nicely.
I added


and the guest silently crashed. xl dmesg showed 1024 as Mem for a second or so.

Pff, try this patch please:
tried, but no effect. The logs attached were made with your patch included.
Thanks for taking time.
