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.
