Hi everybody!
 
I am trying to read file from hvm domU ntfs filesystem. 
If I understand things correctly, Xen emulates hvm-domain harddisk read/write
operations. So I turn to file arch\x86\hvm\emulate.c and function
__hvmemul_read(...) and then
hvmemul_do_mmio(...)/ hvmemul_do_pio(...).
 
Can I read file through I/O ports? And which operations can I use?
Is virtual harddisk access mmio or pio type?
 
Thaks, Olga
