Hi All,

Based on my understanding of the Xen code, I have a small query for you all.

Xen hypervisor can access only a max of 16GB of physical memory
directly on x86 architecture.
Is this correct inference?

So does Xen hypervisor cannot touch memory about 16G directly? Does it
employ some kind of temporary mapping like linux kernel to access
memory above 16G then?

Any help will be appreciated.
