Screenshot

Im VNC-Java-Applet scheinen Bildinformationen aus zwei Sessions angezeigt zu
werden (siehe Screenshots). Mit vncviewer direkt wird alles korrekt angezegit,
der Fehler tritt nur bei dem Java-Applet auf. In diesem Fall war es eine
Überschneidung zwischen Windows7 mit paravirtualisierten Geräten (alex_win7_pv)
und UCS mit paravirtualiserten Geräten (alex_ucs). Der Fehler trat nur in dem
VNC-Fenster der Maschine alex_win7_pv auf, nicht umgekehrt. Das System war KVM
auf xen13.

Hier die Liste der Maschinen im State running (vielleicht zu viele?):
====================
virsh # list
 Id Name                 State
----------------------------------
  1 win7-64-2            running
  2 win7-64-1            running
  3 ucs24-64-slave       running
  5 ucs24-64-descriptipn running
 13 ucs24-64-suspendtest running
 15 win7-3               running
 16 alex_ucs             running
 17 alex_win7_pv         running
====================

Die VNC-Displays sehen korrekt aus:
====================
root@xen13-kvm:~# virsh list | grep running | while read id name state; do echo
$name $(virsh vncdisplay $name); done
win7-64-2 :0
win7-64-1 :1
ucs24-64-slave :2
ucs24-64-descriptipn :4
ucs24-64-suspendtest :3
win7-3 :6
alex_ucs :7
alex_win7_pv :5
ucs2.3-0_basis_amd64 :8
====================

Hier Dumps der beiden betroffenen Maschinen:
