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. > Which settings have to be done in the 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). > Which kernel-config parameters do I have to set or are recommended (my > current k-c is attached)? As per serial-console.txt, add console=ttyS0 console=tty0 to command line. This could be ttyS1, do not remember. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
