[Xen-devel] accessing hvm-domU memory from dom0

[david <david_n@xxxxxx>]

hi,

I have an additional question: Is it possible to access the pseudo 
physical memory of a hvm-domU in dom0 "out of the box", to read/write 
from/into it? If not, what would be the "easiest" way to implement this 
possibility in dom0? Implement a new hypercall which offers this access?
I found intresting functions in the public xen-headers (linux 2.6.32.26) 
like HYPERVISOR_memory_op in include/asm/xen/hypercall.h and the 
structures xen_memory_exchange or xen_memory_map in memory.h. I'm 
currently trying to figure out if this is the functionality I'm looking 
for. Have you any hints for me?
thanks,

best regards,
david
