Re: [Xen-devel] [PATCH v2 2/8] tools: arm: report an error if the guest RAM is too large



Hi Ian,

Due to the layout of the guest physical address space we cannot support more
than 768M of RAM before overrunning the area set aside for the grant table. Due
to the presence of the magic pages at the end of the RAM region guests are
actually limited to 767M.

Catch this case during domain build and fail gracefully instead of obscurely
later on.

This is the only patch in this series which I consider to be suitable for
backporting to Xen 4.4

I agree with you. Without this the guest can crash with weird error.
