virt-manager-0.9.0-7.el6
libvirt-0.9.4-20.el6
python-virtinst-0.600.0-5.el6
qemu-kvm-0.12.1.2-2.204.el6.x86_64

# uname -a
Linux wjw.nay.redhat.com 2.6.32-214.el6.x86_64 #1 SMP Tue Oct 25 19:48:00 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux

How reproducible:
always

Steps to Reproduce:
1. Launch the virt-manager.
2. Install a guest  with spice and qxl:
#virsh dumpxml 6.1demo
....
<graphics type='spice' port='5900' tlsPort='-1' autoport='yes' listen='127.0.0.1'>
      <listen type='address' address='127.0.0.1'/>
    </graphics>
    <video>
      <model type='qxl' vram='65536' heads='1'/>
      <alias name='video0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
    </video>
....

3. Shutdown the guest.
4. Change the graphics type to vnc through the hardware details page of virt-manager.
5. Click apply button.
6. Start the guest successfully with combination of qxl and vnc:
#virsh dumpxml 6.1demo
....
<graphics type='vnc' port='-1' autoport='yes' listen='127.0.0.1'>
      <listen type='address' address='127.0.0.1'/>
    </graphics>
    <video>
      <model type='qxl' vram='65536' heads='1'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
    </video>
....

  
Actual results:
The combination of qxl and vnc exist, guest can be started and cursor disappears.

Expected results:
It's not supported in kvm for the time being and the combination of qxl and vnc should be disabled. Refer to bug 717373.

Comment 3 Cole Robinson 2011-12-09 21:37:02 UTC
Given reduced capacity for virt-manager/virtinst, and since I don't think there is anything fundamentally preventing this from working in the future, just closing this issue as WONTFIX for RHEL. Thanks for the report though
