I have just moved from Xen 4.3 to 4.4. With 4.3 I used the xm toolstack, and I could define multiple serial ports in the config for my Windows domU like so: serial = [ "tcp::4464,server,nowait", "file:/home/ed/logs/Tgt64bcom2.log" ] However, the xl toolstack in 4.4 won't accept a list in the serial definition. If I change it to: serial = "tcp::4464,server,nowait" serial = "file:/home/ed/logs/Tgt64bcom2.log" I end up with a single serial port connected to the file. How can I get two serial ports, with the first connected to a socket and the second connected to a file? Thanks, Ed White
