-If you get no response on the serial port at all, check on the host
-side that the guest is allowed access (see /etc/hostinfod/). Also
-check that the serial port has been set up in libvirt:
-
- virsh dumpxml DOMAIN
-
-(should show a <serial/> clause)
-
-Also check that hostinfod (the daemon) is running on the host.
-
-Note that serial port settings like speed, parity etc. make no
-difference for these emulated serial ports, so that won't be a factor.
-
-If you get an answer from the hostinfo daemon, but it indicates a
-permissions error, check on the host side that the guest is allowed to
-access the particular resource (see /etc/hostinfod/).
-
-[1] _Which_ serial port can vary - you need to either try them one by
-one or ask the host administrator to tell you. We try to stay on the
-second serial port (ttyS1 or COM2) but there are some configurations
-where we get bumped up or down to other serial ports.
