Hey Rusty, This is the way I did the split; patches 1..7 are preparation for multiple ports. Patch 8 adds multiport support. It's the big one since we have to put the header in and retain support for multiple consoles and console resizing. Patch 9 adds port hotplug Patch 10 adds sysfs entries and 12 adds debugfs. Patches 13, 14 and 15 add throttling, caching and unplug features.

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...

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
