Which guest is this? On modern linux distros (anything systemd-based) you should automatically get a login prompt on the serial line in case it is configured as console. Older systems need manual configuration for that. Could also be the system simply hangs here. Try adding "ignore_loglevel" and "drm.debug=0x07" to the kernel command line.
