RE: [Libvir] how to setup usb/serial ports with libvirt & kvm (Fedora 7)

mouse" depending on the input device you've selected. A hack I've found useful for modifying the kvm command-line arguments is to change the <emulator> tag to point to a shell script that invokes kvm as you'd like. For example, /etc/libvirt/kvm-wrapper containing:

#!/bin/sh exec /usr/bin/qemu-kvm "$@" -usbdevice host:1234:5678

might do the trick.

Thanks Jim, A wrapper containing #!/bin/sh exec /usr/bin/qemu-kvm "$@" -serial /dev/ttyUSB0 Did the trick nicely for me mapping the usb/serial converter plugged into the host machine to /dev/ttyS0 on the virtual guest machine. I've now got the virtual guest (RH9) transferred & logging data from the serial port. Regards John
