From 3a3286bf0be8582854b3d451700ae38849b83b7c Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Wed, 12 Oct 2011 12:54:35 +0200 Subject: [PATCH] usb-hid: activate usb tablet / mouse after migration. qemu uses the ps/2 mouse by default. The usb tablet (or mouse) is activated as soon as qemu sees some guest activity on the device, i.e. polling for HID events. That used to work fine for both fresh boot and migration. Remote wakeup support changed the picture though: There will be no polling after migration in case the guest suspended the usb bus, waiting for wakeup events. Result is that the ps/2 mouse stays active. Fix this by activating the usb tablet / mouse in post_load() in case the guest enabled remote wakeup.
