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.
