Hi! Everyone.
Xen hypervisor has 64MB protected memory.But I want to know that how to use
these machine pages.
Are there some APIs or routines to handle the allocation and clean of these
page?

Xen reserves some memory for its own use, and that isn't generally
accessible outside of the hypervisor itself.
