[Qemu-devel] [PATCH v3 0/2] hostmem-file: reject invalid pmem file sizes

[Stefan Hajnoczi]

v3:
 * Added Patch 1 by Igor [Wei]
 * Moved pmem size check after mem_path check [Wei]

Guests started with NVDIMMs larger than the underlying host file produce
confusing errors inside the guest.  This happens because the guest
accesses pages beyond the end of the file.

Check the pmem file size on startup and print a clear error message if
the size is invalid.
