    addhardware: don't remove QXL if VNC graphics are configured
    
    Commit 1a6e803a introduced a fix for bogus behavior of QXL+VNC where
    there was no cursor visible by disabling this configuration in
    virt-manager.  We should enable it again because this is a supported
    configuration and the bug was actually in QEMU.
    
    This is now fixed in qemu-2.6.0 [1] so revert commits 1a6e803a and
    67ca0a9f.

Comment 4 zhoujunqin 2016-07-19 10:31:03 UTC 
I can reproduce this issue with package
virt-manager-1.3.2-1.el7.noarch

Then try to verify with new build:
virt-manager-1.4.0-1.el7.noarch
libvirt-2.0.0-2.el7.x86_64
qemu-kvm-rhev-2.6.0-14.el7.x86_64
libvirt-python-2.0.0-1.el7.x86_64

Steps:
1. Prepare a health guest with
Display: vnc
Video: cirrus

2. Scenario-1 change video model to QXL

2.1 Launch virt-manager, and try to change video to other mode: QXL
# virt-manager
Select virtual machine 'rhel6.8latest'--->Open--->'Show virtual machine details'--->change video model from 'cirrus' to 'qxl'

Result: 'QXL' is displayed in video model and can be selected.
        Virtual machine with vnc+qxl can boot up with no error.

3. Scenario-2 add video model QXL

3.1 Shut off guest and restore its configuration to vnc+cirrus.

In 'Show virtual machine details' page, add new Video to virtual machine.

Result: QXL video model is showed and can be add as second video to virtual    machine when display is vnc.
        Virtual machine with vnc+cirrus+qxl can boot up with no error.
        
Since QXL is added to video model when display is vnc in virt-manager, move this bug from ON_QA to VERIFIED.
