Traditional speed settings fairly meaningless for emulated hardware,
as the emulation will transfer data as fast as possible. If you are
connecting the virtual serial port to a host serial port though,
QEMU will pass through settings. ie if the guest OS sets the serial
device speed, QEMU will update the host serial port to match. So there
is nothing to configure from libvirt's POV. The guest OS initiated
changes should just "do the right thing"
