I hope this is not to far off topic.
I have a Windows 2003 guest on a CentOS 5.5 KVM host. I need to use the serial port on the win2003 guest for the application it is serving.
I have no idea what needs to be done but it looks like the linux host is trying to use the serial port as the priamary console but I don't really understand what that is or where it is configured.
What I need is for the host to ignore any traffice over the serial port and to pass it to the guest.
On the host, ls -l /dev | grep ttyS, returns: crw-rw---- 1 root uucp 4, 64 Jul 6 10:17 ttyS0 crw-rw---- 1 root uucp 4, 65 Jul 6 10:17 ttyS1 crw-rw---- 1 root uucp 4, 66 Jul 6 10:17 ttyS2 crw-rw---- 1 root uucp 4, 67 Jul 6 10:17 ttyS3 It only has 1 serial port so I don't know why ttyS1-S3 are listed.
On the guest it says that Com1 is configured and working properly.
On the Virtual Machine Hardware tab of the guest it lists a Serial 0. Details: Serial Device (Priamary Console) Device Type: pty Target Port: 0 Source Path: /dev/pts/2
Any help would be greatly appreaciated. Thanks!!!

If it is possible to pass through a physical serial port to a virtual machine ( and I do not know if it is, sorry, just bla bla ;-), then i would expect it to be guest os independent, that means it has to be configured in the host ?

if its not plug and play, setserial(8), then use whatever /dev/ttyS# its configured as.

The following link describes how to configure libvirt for serial port pass through. http://empegbbs.com/ubbthreads.php?ubb=showflat&Number=314827
