I use Vmware Player (for historical reasons); as of version 3.x it is
self contained, i.e. it allows you to create new VM.

Add new serial port (may be one is included by default, do not know -
it is not listed in new VM); then serial port appears in removable
devices and you can connect/disconnect it at any time. You can
redirect output to file or connect to socket (not tried).

As per serial-console.txt, add

console=ttyS0 console=tty0

to command line. This could be ttyS1, do not remember.
