I've up and running a VirtualBox guest with a serial as well as a virtual console. From the compiled consoles test (-DTEST_PROGRAM) I see: g243:~ # ./consoles /dev/console /dev/tty7: id=0 (reconnect) /dev/ttyS0: id=1 (reconnect) g243:~ # cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-3.4.11-2.16-desktop root=UUID=5ece074f-824b-45b0-8fa6-aa61c06beb87 resume=/dev/disk/by-id/ata-VBOX_HARDDISK_VB96c77b27-f0603953-part1 splash=silent console=ttyS0,115200 console=tty0 showopts > For such things a VirtualBox or KVM client is usefull, if a serial > console is used then you can see both of the consoles.

For the VirtualBox I use a sub directory /dev/vboxtty/ owned and writable by the group vboxusers. Below this the VirtualBox creates the ttyS0 as a socket pair and I start a simple script using socat and screen with: #!/bin/bash : ${tty:=ttyS0} dir=/dev/vboxtty pty=$dir/tty${tty#ttyS} socat unix-connect:$dir/ttyS0,oobinline pty,link=$pty,b38400,parenb=1,cs8,istrip=0,icanon=1 & exec screen -O -A -f $pty b38400,parenb=1,cs8,istrip=0,icanon=1 with this one can see the boot messages on both the serial console and on the window used by the VirtualBox for its own virtual console(s).
