Subject: [Xen-devel] [PATCH RFC 1/3] virtio infrastructure

This attempts to implement a "virtual I/O" layer which should 
allow common drivers to be efficiently used across most 
virtual I/O mechanisms.  It will no-doubt need further enhancement.

Rusty

Could you please clarify what is the purpose of this "virtual I/O"
layer?
At least for networking, why isn't the current linux net device
abstraction sufficient for hiding the details of different virtual
devices implementations? What am I missing?

Thanks

Renato
