Hello attaching a patch that allows disabling the PS/2 mouse.
I use this feature to prevent Windows XP guest with recent Synaptics driver installed from crashing at boot. The Synaptics driver is somewhat misguided in that (unlike earlier versions) it installs on pretty much any PS/2 hardware (real or virtual). There is no problem with this on real hardware. You just get the Synaptics control panel running uselessly. On kvm Windows panics during boot. This patch allows Windows to boot. No PS/2 mouse is detected neither in Windows nor Linux. However, I am not sure this is the right approach to disabling the mouse. I would appreciate if somebody reviewed the patch and either pointed out issues or merged it into qemu and kvm so that I don't have to repeatedly patch my binaries. While this error can be worked around in the guest and it is not obvious which side is wrong the ability to turn off the mouse might be useful in some other situations as well. Thanks Michal
