Hi, 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 = "<devices><serial 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 ..? regards Bala On Mon, Sep 12, 2011 at 4:24 PM, Stefan Hajnoczi <stefa...@gmail.com> wrote: > On Mon, Sep 12, 2011 at 03:49:53PM +0530, bala suru wrote: > > Can I do this on the running VMs ..?, > > I'm using opennebula to spawn the VMs, so it would be good if edit before > > spawning the VMs.. > > 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: > http://opennebula.org/documentation:rel2.2:kvmg > > Stefan >
