The type='pty' attribute in the <serial> element causes a Pseudo TTY to be
allocated on the host side via "/dev/ptmx", which is meant to be
interacted with via "virsh console" or similar.
That's not how a firmware log is typically viewed or saved. Replace
type='pty' with type='file', and also provide an example <source> element
(with the pathname of the logfile), similarly to how the <serial> example
just above provides a <source> element too.
