Implement virtio-net driver

[Jakub Jermář]

Implement a native HelenOS driver for virtio network device.

Details

Virtio is a ​specification for virtual I/O devices that allows to use paravirtualized drivers with an otherwise fully-virtualized guest OS, leading to more efficient I/O.

Virtio network device (virtio-net) is currently supported by KVM and VirtualBox.

The new driver should be realized as a standalone service which plugs itself into the HelenOS networking stack and implements the network interface card interface in the virtio-net specific way.

What Gains and Benefits will this bring?

HelenOS might need a virtio network device driver if we want to run it in a KVM-hosting and serve some web content (e.g. microkernel.info) to the public from it.

Difficulty

medium to high

Required skills

A successful applicant will have good skills of programming in the C language and the ability to learn and use HelenOS specific I/O functions. A successful applicant should have a fair understanding of the workings of the networking stack and the NICF too.
