Under bug # 886338 an instruction was added to the documentation for building a custom disk image indicating users should add these parameters to the kernel arguments to ensure console output is visible via nova, the dashboard, and anything else that might need to access it: serial=tty0 console=ttyS0,115200n8 As it turns out in RHEL at least serial isn't a valid argument (or at least is a noop) and does nothing, current thinking is this should actually read: console=ttyS0,115200n8 console=tty0 This needs to be confirmed though.
Background: Graeme indicates that the info in the prior bug came from http://unix.stackexchange.com/questions/100/how-do-i-connect-a-serial-terminal-to-a-kvm-instance, and that in turn traces back to http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=507650#29, which I suspect is simply in error.
