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 Daniel Berrangé 2009-08-03 14:57:10 UTC 
Description of problem:
Management apps need to know when a VNC/SPICE client connects/disconnects to/from a QEMU instance. 

libvirt API needs to be extended to allow notification callbacks for this information. The QEMU driver needs to be extended to understand the RHEL-custom and/or QEMU upstream (if implemented) monitor event syntax.

Version-Release number of selected component (if applicable):
0.7.0

This patch does VNC events:

http://www.redhat.com/archives/libvir-list/2010-March/msg00817.html

Can be extended for SPICE events in similar way.
Comment 9 Daniel Berrangé 2010-04-12 18:56:13 UTC 
The SPICE events are now also included

Comment 13 Johnny Liu 2010-06-22 10:08:21 UTC 
Verified the defect with libvirt-0.8.1-9.el6.x86_64, and PASSED.


1. Start a domain with vnc/spice graphic:
For vnc:
...
    <graphics type='vnc' port='5900' autoport='yes' listen='127.0.0.1' keymap='en-us'/>
...
For spice:
...
<graphics type='spice' port='5900' autoport='no' keymap='en-us'/>
...

2. In a terminal, run the following python script to check the output about vnc event:
# python /usr/share/doc/libvirt-python-0.8.1/events-python/event-test.py

3. Use virt-viewer or spicec client to connect/disconnect guest desktop

4. On the terminal, the following python script output about vnc event is seen:
For vnc:
...
myDomainEventGraphicsCallback: Domain demo(2) 0 none
myDomainEventGraphicsCallback: Domain demo(2) 1 none
myDomainEventGraphicsCallback: Domain demo(2) 2 none
...
For spice:
...
myDomainEventGraphicsCallback: Domain demo(3) 0 none
myDomainEventGraphicsCallback: Domain demo(3) 1 none
myDomainEventGraphicsCallback: Domain demo(3) 2 none
...
