hw/vmmouse.c: Disable vmmouse after reboot
Bugfix after reboot when vmmouse was enabled and another OS which uses e.g. PS/2 mouse. Details: When a guest activated the vmmouse followed by a reboot the vmmouse was still enabled and the PS/2 mouse was therefore unsusable. When another guest is then booted without vmmouse support (e.g. PS/2 mouse) the mouse is not working. Reason is that VMMouse has priority and disables all other mouse entities and therefore must be disabled on reset. Testscenario: 1.) Boot e.g. OS with VMMouse support (e.g. Windows with VMMouse tools) 2.) reboot 3.) Boot e.g. OS without VMMouse support (e.g. DOS) => PS/2 mouse doesn't work any more. Fixes that issue. Testscenario 2 by Jan Kiszka <jan.kiszka@siemens.com>: Confirm that this patch fixes a real issue. Setup: qemu.git, opensuse 11.4 guest, SDL graphic, system_reset while guest is using the vmmouse. Without the patch, the vmmouse become unusable after the reboot. Also, the mouse stays in absolute mode even before X starts again. Fixed by: Disabling the vmmouse in its reset handler.
