Red Hat Bugzilla – Bug 432232
The mouse inside the guest window "freezes" when the host mouse reaches the screen boundary
Last modified: 2009-05-01 16:24:56 EDT
Description of problem:
When the mouse cursor of the host desktop reaches the boundary of the screen,
the mouse cursor inside the window of the fully virtualized guest also stops
despite it still may be somewhere in the middle. The "freezing" also stays
when the mouse pointer is "grabbed" (the host mouse is not visible). However
when the host mouse is visible it is easier to understand the root of the
This problem reduces the useability of the virtualized host.
RHEL Desktop 5 (workstation with virtualization):
Steps to Reproduce:
1. Install Windows XP fully virtualized. Configure everything so that the
Windows guest desktop window would cover the major part of the host screen.
2. Move the mouse, watching both host and guest mouse cursors.
3. When the host cursor reaches the boundary of the real screen, the guest
cursor also "freezes".
4. Repeat the same with the mouse "grabbed" inside the guest window. You will
observe the same stops, just they nature at this time will be more mysterious.
The mouse cursor in the guest desktop stops mysteriously inside the window
area (mouse grabbing does not help).
The mouse cursor in the guest desktop moves when I move the physical mouse on
my table, unless is really at the boundary of the virtual desktop.
