Read domU filesystem
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

running slow, "xm top" or
