libvirt snippet (add to ):
Was thinking about the motivation to add the virtio serial device.
AFAIU this can provide a console in bios/early boot based on "virtio".
Currently we can only get it with emulated PTY device which is slow
because of frequent VMEXITS because

Hi Gerd,
This seems useful - how do I use it?
bare qemu (with guest console on stdin/stdout):
qemu-system-x86_64 \
-enable-kvm -nodefaults -display none \
-bios Build/OvmfX64/DEBUG_GCC5/FV/OVMF.fd \
-chardev stdio,id=hvc0 \
-device virtio-serial-pci \
