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.

Doc Type: Bug Fix
Doc Text:
For content author, I think users did not see this bug, but it was discovered during development. The Problem: Upon (linux) guest panic, a spice-client connected to the VM caused client's keyboard leds to blink and capslock to turn on/off continuously, in non-spice-client windows too. The Fix: Blocking keyboard modifier events when spice-client windows is not in-focus. That means when the user focuses out of spice-client window (focus on a different window), blinks stop blinking and caps-lock does not turn on/off.

Red Hat Product Errata RHBA-2011:0583 0 normal SHIPPED_LIVE libcacard and spice-client bug and enhancement update 2011-05-19 09:37:34 UTC

Description Hans de Goede 2010-08-24 19:10:14 UTC 
Steps to Reproduce:
1. Run linux kernel in guest make it panic (no initrd cannot find root for example)
2. Connect spice client to the vm with the blinking keyb leds from the kernel panic
3. Switch to another window and try to type something, notice how every few ohter letters the letters change from caps to lowercase or vica versa.
Comment 2 Marc-Andre Lureau 2010-11-02 00:30:04 UTC 
I have a trivial workaround for that bug, just blocking modifier events when focus_out(). It could be done differently.

http://gitorious.org/~elmarco/spice/elmarco-spice/commit/ae776586b96400070214d85ad073db49bb6925ef

I'll post it on the mailing list for review.

Additionally, should we restore keyboard modifiers when going out of focus? I think we should, given that Spice currently offers a full remote desktop client which feels like a separate machine. However, if the remote windows would be managed by the client, and the root window hidden, then this behavior would be bad.
Comment 4 Alon Levy 2011-01-17 16:43:02 UTC 
Marc's patch is now in upstream, commit:

 84c0156 client inputs: stop blinking keyboard when out of focus
Comment 5 Hans de Goede 2011-01-25 13:52:19 UTC 
A new spice-client-0.7.2-1.el6 fixing this has been build, moving to modified.
Comment 7 Lubos Kocman 2011-03-09 13:00:46 UTC 
Verified on spice-client-0.8.0-1.el6.x86_64.
