once I suggested the following to communicate between to uml instances: uml1> stty -F /dev/ttyS0 uml1> dmesg| grep Serial Serial line 0 assigned device '/dev/pts/9' uml2> stty -F /dev/ttyS0 uml2> dmesg| grep Serial Serial line 0 assigned device '/dev/pts/5' uml2> cat < /dev/pts/5 >> /dev/pts/9 & ; cat > /dev/pts/5 >> /dev/pts/9 & can you please try it, using uml2 as a server/host and the other as the uml instance. But before have a look a the /uml/etc/inittab to se if you uncomment the line with your serial device, the same on the server/host. > > > or do I need hostfs access to the device node? > > That wouldn't work. As Blaisorblade said it is not your need, because it enables the chance for uml to access the host filesystem in read/write mode.
