This patch enables the migration of Qemu VMs between hosts of different endianess. I tested this by migrating a i686 VM between a x86 and ppc64 host.

ACK with that nit fixed.
I don't think it's necessary to include it there: # rpm -q --whatprovides /usr/include/byteswap.h glibc-headers-2.12.90-21.x86_64 Stefan
