Fixed upstream now:

commit 0910c8dcfc38d03178d0cb6f2beb41a192eb45be
Author: Cole Robinson <crobinso>
Date:   Thu Mar 2 15:08:32 2017 -0500

    domain: Use libvirt.VIR_DOMAIN_OPEN_GRAPHICS_SKIPAUTH (bug 1379581)
    
    It's what virt-viewer uses, and apparently it's needed for VNC
    listen type=none

Comment 5 zhoujunqin 2017-03-20 06:38:13 UTC
I can reproduce this bug with package:
virt-manager-1.4.0-2.el7.noarch

Then try to verify this bug with new build:
virt-manager-1.4.1-1.el7.noarch
virt-manager-common-1.4.1-1.el7.noarch
virt-install-1.4.1-1.el7.noarch
libvirt-3.1.0-2.el7.x86_64
spice-gtk3-0.33-1.el7.x86_64

Steps:
1.Launch virt-manager:
# virt-manager

2. Prepare a healthy vm in shutdown status without Display, then check the hardware tab in the Virtual Machine Details window.

3.Click Add Hardware to add a  vnc display with "listen type = none"
Type: VNC server
Listen Type: None
Others as default setting, then click "Apply".

4. VNC display added successfully, then start guest and open guest console.

Result:
Guest boots up successfully and guest's graphic shows normally in virt-manager, so move this bug from ON_QA to VERIFIED.
