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.

Previously, when opening a connection to a Windows guest on a four monitors host, only one monitor gets enabled. With this update, the spice agent copes with monitor configuration refresh during reconfiguration, and all monitors will get enabled.

Description CongDong 2014-06-19 11:00:44 UTC 
Description of problem:
remote-viewer only show one display if connect windows 7 guest on a 4 monitors machine, if try 2 or 3 times, it works.

Version-Release number of selected component (if applicable):
virt-viewer-0.6.0-7.el6.x86_64
spice-server-0.12.4-9.el6.x86_64
spice-gtk-python-0.22-4.el6.x86_64
spice-vdagent-0.14.0-3.el6_5.x86_64
spice-gtk-0.22-4.el6.x86_64
spice-xpi-2.7-24.el6.x86_64
spice-glib-0.22-4.el6.x86_64
virtio-win-1.6.8-4.el6

How reproducible:
100%

Steps to Reproduce:
1. Install a win7 guest on a 4 monitors machine, install spice agent and qxl dirver in it.
2. configure it with only one display first
# virt-viewer $vm
make sure only one display comes out
3. close virt-viewer, use remote-viewer connect the guest
# remote-viewer spice://$ip/$port --full-screen --debug

Actual results:
Stpe3, only two displays comes out with fullscreen,
but seems 4 displays are ok form log.
# cat $log
(remote-viewer:17024): remote-viewer-DEBUG: Insert window 0 0x1a70840
(remote-viewer:17024): remote-viewer-DEBUG: Insert window 1 0x1a70e40
(remote-viewer:17024): remote-viewer-DEBUG: Insert window 2 0x1ab9e10
(remote-viewer:17024): remote-viewer-DEBUG: Insert window 3 0x1ae1240
(remote-viewer:17024): remote-viewer-DEBUG: fullscreen display 0: 1
(remote-viewer:17024): remote-viewer-DEBUG: fullscreen display 1: 1
(remote-viewer:17024): remote-viewer-DEBUG: fullscreen display 3: 1
(remote-viewer:17024): remote-viewer-DEBUG: fullscreen display 2: 1
...

when I connect the guest second time, 3 displays comes out
when I connect it third time, 4 displays comes out.

Expected results:
4 displays should come out in fullscreen mode when I connect it first time

This is unlikely a client bug, auto-conf is correct:

I can reproduce, using upstream spice-guest-tools-0.74.exe on rhevm 3.4

However, I couldn't reproduce on f20 with qxl 6.1.0.10018 and spice agent 0.7.2.7-1b0e

actually, result is random, looks like something racy, ok moving component

CongDong, no need for logs, it can be reproduced.

thanks

Comment 7 Marc-Andre Lureau 2014-06-19 16:03:14 UTC 
iirc, this commit was solving this issue, and was later reverted because I didn't manage to find reproducer:

commit 67c1bcf49367d1726033b298a8ab016b4e22cf23
Author: Marc-André Lureau <marcandre.lureau>
Date:   Sat Mar 16 00:55:15 2013 +0100

    Refresh monitor config only when needed
    
    Somehow wnd_proc()->get_display() may be reentered during ChangeDisplaySettings
