Description of problem:

Visit the RHEL guest VM via the Hyper-V Manager installed on the physical machine. There are two mouse icons on the guest screen. one is a dot, and the other is a arrow. When moving the mouse, both of them will move. Only the mouse with arrow is valid for using. It's not very convenient for the customer using.


Version-Release number of selected component (if applicable):
Host: Windows 2008 R2 Hyper-V (6.1.7600.16385)
Guest: RHEL5.9 guest (2.6.18-336.el5)
Pv drivers: 
# lsmod |grep hv_*
hid_base_hv            68177  1 hid_hyperv
hv_netvsc              25665  0 
hv_utils               12001  0 
hv_storvsc             17601  3 
hv_vmbus               30265  4 hid_hyperv,hv_netvsc,hv_utils,hv_storvsc

How reproducible:
100%

Steps to Reproduce:
1.Login a guest with graphical output via Hyper-V Manager which is installed on the physical machine. 
2.Move the mouse and use it to do some operations.


Actual results:

At step2, there are two icons on the guest screen and the two icons don't track each other well.

Expected results:

At step2, there is one icons or the two icons track each other well.


Additional info:
1. Test the mouse with the windows guest on Hyper-V host. Two icons track each other well.
2. There is one mouse icon on the guest RHEL5.9 Server-base (2.6.18-333.el5) without the hyper-v pv drivers. The mouse works well on the guest screen, although the mouse icon is bound into the virtual machine. Use "Ctrl + Alt + left" to unbound it.
