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
