Running kvm on AMD 64 bit, this problem occurs for 64 guests regardless
of the guest mouse driver (mouse or vmmouse). It does not affect 32bit

This is happening to me with Lucid 64 using KVM on Fedora. The mouse moving
normally causes Lucid to grind to a halt and the mouse becomes barely usable.

I have tried this and removing xserver-xorg-input-vmmouse did in fact
make the system usable again on maverick.

@Julian: Does removing xserver-xorg-input-vmmouse from the client fix the
issue?
Also, what cpu do you have? I am wondering if this might be unique to AMD
processors.

Just a precision (may not be obvious to everyone): xserver-xorg-input-
vmmouse has to be uninstalled on the virtualized system, not in the
hosting system. Which is not very convenient when running a live CD,
because the user has to install it, then restart the X server (each time

Setting the live cd to run in safe mode works around the issue.

I'm seeing almost the same behavior in an 8.04.4 guest on a 10.04 host.
The mouse pointer movement in the guest was ABYSMALLY slow until I
edited /etc/X11/xorg.conf to use 'mouse' instead of 'vmmouse'. After
doing that and restarting X, mouse performance inside the guest matched
that of the host.
The high cpu usage was on the host only when the mouse on the guest was
being moved rapidly.

The problem here is that clicking install causes the screen to flicker and the

Unlike Ezra Reeves, I only have the mouse issue. When I move my mouse, the
xorg process of the VM goes to 100% (I can get more CPU usage if I enable
many processors), and so does the KVM process. It happens:
- with KVM native display or VNC
- using KVM directly or through libvirt
The rest seems
This bug affects me as well; exact same symptoms as described above,

If I am using kvm-qemu and not VMware, should the vmmouse driver be active?
I will double check with the vmmouse_detect thing, but xorg is logging:
(II) VMWARE(0): VMMOUSE DEVICE_INIT
(II) VMWARE(0): VMMOUSE DEVICE_ON
(II) VMWARE(0): vmmouse enabled
...
(II) VMWARE(0): vmmouse enable absolute mode
Yes, vmmouse is the driver that kvm supports to enable the mouse cursor
automatically entering and leaving the guests window.
