That magic is passed when building QEMU within the Xen tree (I don't 
know why, it's ugly) so this is presumably when building QEMU by hand 
outside of the Xen build system?
The patch to make QEMU use the new dmops will be part of the next 
version of Ian's "xen: xen-domid-restrict improvements" patch series. In 
the meantime, you can find the patch here:
https://github.com/rosslagerwall/qemu/commit/37d58e0c8e9c6df7f7e2464a37d1de2675da7e81
