cd9ca71b25 dev: Rename VirtIO PCI debug flag 
Rename VIOPci -> VIOIface to avoid having a separate flag for the MMIO
interface.

3f7a9348dd dev: Add support for 9p proxying over VirtIO 
This patch adds support for 9p filesystem proxying over VirtIO. It can
currently operate by connecting to a 9p server over a socket
(VirtIO9PSocket) or by starting the diod 9p server and connecting over
pipe (VirtIO9PDiod).


*WARNING*: Checkpoints are currently not supported for systems with 9p
 proxies!

bf2c2183c6 dev, pci: Implement basic VirtIO support 
This patch adds support for VirtIO over the PCI bus. It does so by
providing the following new SimObjects:

 * VirtIODeviceBase - Abstract base class for VirtIO devices.
 * PciVirtIO - VirtIO PCI transport interface.

A VirtIO device is hooked up to the guest system by adding a PciVirtIO
device to the PCI bus and connecting it to a VirtIO device using the
vio parameter.

New VirtIO devices should inherit from VirtIODevice base and
implementing one or more VirtQueues. The VirtQueues are usually
device-specific and all derive from the VirtQueue class. Queues must
be registered with the base class from the constructor since the
device assumes that the number of queues stay constant.
