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.

Description Geyang Kong 2012-03-13 09:09:56 UTC 
Description of problem:
  Virt-viewer form cannot be closed through GUI when it connects to a VNC guest.

Version-Release number of selected component (if applicable):

virt-viewer-0.5.2-1.el6.x86_64

How reproducible:
100%

Steps to Reproduce:

1. Make sure there is a running guest with VNC display.

2. Run #virt-viewer <guest-name> --debug

3. Make sure you can see the console, then try to close it by clicking 'X' or using 'File->Quit' from menu.

Actual results:

1. There is a string said 'connected to graphic server' console but virt-viewer form is still there.

2. You can only use ctrl+c in terminal to close it.

3. When try to close it again. There will be a Gtk warning like below in terminal.
----------------------------------------------------------------------------------------
(virt-viewer:17926): Gtk-WARNING **: A floating object was finalized. This means that someone
called g_object_unref() on an object that had only a floating
reference; the initial floating reference is not owned by anyone
and must be removed with g_object_ref_sink().
** (virt-viewer:17926): DEBUG: Dispatch handler 5 1 0x945740
** (virt-viewer:17926): DEBUG: Update timeout 0x9451e0 1 0
** (virt-viewer:17926): DEBUG: Dispatch timeout 0x9451e0 0x7fb95226f080 1 0x945590
** (virt-viewer:17926): DEBUG: Update timeout 0x9451e0 1 -1
----------------------------------------------------------------------------------------

Expected results:

1. Virt-viewer form can be closed normally.

Additional info:

1. This issue cannot be reproduced by spice.

2. This issue cannot be reproduced by virt-viewer-0.5.1-1.el6.x86_64.

3. There is nothing in libvirtd.log, so I didn't attach it.

Comment 3 Daniel Berrangé 2012-04-03 15:22:34 UTC 
There are two bugs here.

1. The failure to actually close the window. This regression is caused by

commit 8ec03e50974330c3813df68e16b38702e216f9fd
Author: Hans de Goede <hdegoede>
Date:   Sun Mar 4 19:02:31 2012 +0100

    virt_viewer_app_quit: Cleanly close the connection before quiting
    
    Even though the previous patches in this series ensure that the session
    gets properly finalized, we still need to wait for the disconnect signal,
    as spice-glib uses co-routines which need some time to cleanly close the
    connection / session.

2. The error "A floating object was finalized.". This regression is caused by

commit 7c1414b31859eaa00421d347408d5dc6168ab12d
Author: Hans de Goede <hdegoede>
Date:   Sun Mar 4 17:34:10 2012 +0100

    virt-viewer-app: unref the session on dispose
    
    With this patch combined with the previous patches in this series, the
    VirtViewerSession (finally) gets properly finalized on exit.

Comment 5 zhe peng 2012-04-05 05:13:29 UTC 
this bug can reproduce with:
virt-viewer-0.5.2-1.el6.x86_64

verify with:
virt-viewer-0.5.2-4.el6.x86_64
libvirt-0.9.10-6.el6.x86_64

step:
1. Make sure there is a running guest with VNC display.

2. Run #virt-viewer <guest-name> --debug

3. Make sure you can see the console, then try to close it by clicking 'X' or
using 'File->Quit' from menu.

Virt-viewer can be closed normally now.
Comment 7 zhe peng 2012-04-05 08:54:09 UTC
