Description Chris Lalancette 2008-03-26 17:51:49 UTC

Description of problem:
I'm using the RHEL5.2 beta bits, and when booting a fully virtualized guest, the
mouse pointer is extremely jumpy.  That is, I can move the mouse around, but
every half a second or so the mouse will freeze for a moment and stop moving.  A
second or so later, it will unfreeze and continue to track.  This happened on
both an i386 and x86_64 RHEL-5 guest on an x86_64 host.  Package versions:

kernel-xen-2.6.18-84.el5
gtk-vnc-0.3.2-1.el5
virt-viewer-0.0.2-1.el5
virt-manager-0.5.3-4.el5
libvirt-0.3.3-5.el5
xen-3.0.3-58.el5

The machine in question is an AMD RevF.

Seeing the same thing with RHEL4 FV guests.

my dom0 revs:

kernel-xen-2.6.18-84.el5  (same)
gtk-vnc-0.3.2-1.el5       (same)
virt-viewer-0.0.2-1.el5   (same)
virt-manager-0.5.3-2.el5  (-2 revs older)
libvirt-0.3.3-5.el5       (same)
xen-3.0.3-53.el5          (-5 revs older)

My machine is a Dell SC440 (dual core Intel).
Has 2GB on it; dom0 using 1.5GB; guest using 0.5MB

from cat /proc/cpuinfo:
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 15

Can you try accessing the console with regular 'vncviewer' and tell me if it
exhibits the same jumpy pointer behaviour ? That will let us know if its a
viewer problem, or a QEMU problem
