Hi
folks,
I have some
issues when trying to copy the memory block from Dom0 to DomU using the
xc_map_foreign_range.
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 blockfrom 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). Thanks.Swaminathan VasudevanSystems Software Engineer (TC)
