That ought to be connecting to the guest's serial console.

However I think the problem could be that '-x' is not compatible with
CD-ROM booting, so that kernel command line argument goes nowhere, so
the kernel never sends anything to the serial port.

You could try using 'virt-dmesg' to see what the guest kernel is
really doing and what command line it sees.
