Hi folks,
I have some issues when trying to copy the memory block from Dom0 to DomU using the
It throws me an error saying that it
"xc_map_foreign_range: ioctl failed" or else sometimes it says that it could not map the "PT".
Could you tell me what might be the problem. Or else if you have a sample code that I could take a look at as to how to copy the memory block
from the dom0 to domU.
I am running xen 3.3.1 on Centos and using a Ubuntu as my Guest OS, running in HVM  mode (Fully virtualized).
