Thanks for the help , Now I could do cat /dev/ttyS0  , no error . it runs well .

But I need to connect a some USB device which will create a virtual serialport called /dev/ttyACM0, I cloud not see this on the Vm running ..

This XML format I used
RAW = [ type = "kvm",
          data = "" type=\"pty\"><source path=\"/dev/pts/5\"/><target port=\"0\"/></serial><console type=\"pty\" tty=\"/dev/pts/5\"><source path=\"/dev/pts/5\"/><target port=\"0\"/></console></devices>" ]

Have I missed out anything ..?

I don't think you can do this on a running VM.

At the bottom of this page they show how you can add the serial port
libvirt domain XML in OpenNebula:
