Andrew, with eab806a097b ("tools/libxc: x86 PV restore code") the only call of xc_domain_populate_physmap_exact was added to the new restore code. This call always sets order=0. The old migration code did consider superpages, the new one does not.
What is the reason for not using superpages when populating a HVM domU? I supposed the first iteration would allocate all of the required memory for a domU, perhaps as superpages. ~ollowing iterations would just refill existing pages. Olaf
