RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 3 Cole Robinson 2017-03-02 20:13:28 UTC 
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.
