Yes, I'm connecting a USB to serial device to the host (ubuntu 11.04) and I
want that serial port on my VM .
I tried the solution you have suggested but still same problem , can  not
see the virtual serial port (ttyACM0) on VM but I could see on the HOST .

The following is the line  I have tried .
 RAW = [ type = "kvm",
          data = "<devices><serial type=\"dev\"><source
path=\"/dev/ttyACM0\"/><target port=\"0\"/></serial><console type=\"pty\"
tty=\"/dev/pts/5\"><source path=\"/dev/pts/5\"/><target
port=\"0\"/></console></devices>" ]
