What is the advantage of virtio-console, compared to the standard serial
port?
I cannot talk about the qemu version, but looking at kuli (the experimental
kvm userspace for s390) these things come into my mind:
- it is not limited to to serial speed settings (9600..115200 etc.)
Neither is the emulated serial port :)
- the kernel driver of virtio_console has console resizing support. Adding
resize support into qemu should be an easy addon patch, it was quite easy in
kuli. This would be really cool. Running kvm with nographic and virtio
console on stdio would allow vim or mc to get notifications about resizes of
the underlying console - like running native.
That's good to have, certainly.
- will work on platforms without a serial port (like s390)
I'm looking forward to the emulated punch card device.
Maybe we can also use this to move existing lguest guests into kvm
Won't work due to lguest's abilessness.

Do not meddle in the internals of kernels, for they are subtle and quick to
panic.
