Comment 4 for bug 259821

Ok
So i made a wrapper to solve my problem that will execute the options I want on the selected vm.

The solution was to rename kvm to kvm.original and create a kvm bash script like this:

#!/bin/bash
ARGV1="$@"
ARGV2="-M pc -m 512 -smp 1 -monitor pty -no-acpi -drive file=/home/virt-images/WindowsXP.qcow,if=ide,boot=on -drive file=/dev/cdrom,if=ide,media=cdrom -net nic,macaddr=52:54:00:56:c5:48,vlan=0 -net tap,ifname=,script=,vlan=0 -usb -vnc 0.0.0.0:0"

if [ "$ARGV1" == "$ARGV2" ]
 then
 exec /usr/bin/kvm.original $@ -usbdevice host:0529:001
fi
exec /usr/bin/kvm.original $@

Hope this helps someone.

Thanks anyway
