Hi,

By putting some stupid workaround in dist-tools creation step as
reported earlier
i now have a Ubuntu ARM system running on OMAP5 Dom0.


I finally got a couple of DomUs using a ramdisk running on OMAP5 :)

The problem was due to the dtb for DomU allocating only 32MB of memory.
Once i increased that the error reported earlier went away.

The comment in xenvm-4.2.dts in the kernel seems to suggest the memory
node gets updated

memory@80000000 {
         device_type = "memory";
         /* this field is going to be adjusted by the hypervisor */
         reg = <0 0x80000000 0 0x08000000>;
};

Is there some config option to get this working as expected?

Not yet. Ian Campbell is working on the auto-generation of domU device tree.
For now, if you want to change the amount of memory, you need to modify the device tree yourself and xl configuration file.

Cheers,

Julien
