Multiple ports support for virtio_console; major number for dev
Hello,
This is the patch that I have for adding support for multiple ports to
virtio_console. It's pretty stable in my testing so far and the memory
corruption that I had earlier has been resolved in linux-next so I'm
proposing this for inclusion.
This currently uses device major number 60 from the experimental range;
Alan could you please reserve a new major number for virtio_console?

Multiple port support for virtio-console
Hello all,
Here is a new iteration of the patch series that implements a
transport for guest and host communications.
I've tested for compatibility (old qemu & new kernel, new qemu & old
kernel, new qemu & new kernel) and it all works fine*.
There are a few items on my todo list but this works well.
New since last send:
- live migration support**
- write path in the guest
