I would also like to add the following comment from Blaisorblade to the previously mentioned email: ****************************************************************** > > I there a way to connect to UML machines with a virtual serial cable? > 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' (This assumes having ssl=pts set on the UML command line or in the default config, which is the default however). > uml2> cat < /dev/pts/5 >> /dev/pts/9 & ; cat > /dev/pts/5 >> /dev/pts/9 > & This command should likely be done on the host, right? Otherwise I don't see how you get /dev/pts/5 and /dev/pts/9 on uml2. > it should be something like this: you need to replicate a *virtual cross > cable* I believe the above should work but probably there are better ways to achieve this - like attaching one guest tty directly to an host TTY. Likely, you'd attach one UML to a host master PTY (/dev/ttypX ?) and the other to a host slave PTY (/dev/ptypX ?). ****************************************************************** It seems correct for your own info to add these info, too, since I myself have a lot to understand and achieve from Paolo and the UML team (Thanx for your constant help).
