This is happening to me with Lucid 64 using KVM on Fedora. The mouse moving

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

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
he runs the live

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:

- using KVM directly or through libvirt

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
With the fixed vmmouse package, vmmouse_detect should return 0. If it
returns 1, xorg should not be using the vmmouse driver.

Just moving the mouse from one end to the other should definitely not
cause 100% cpu usage.
Unfortunately, I cannot reproduce this.

after reboot.
