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.

Fixed In Version: qemu-kvm-rhev-2.10.0-1.el7
Doc Type: Bug Fix
Doc Text:
Prior to this update, sending the BREAK or PAUSE keys over the VNC or SPICE client was not properly handled and had no effect in the guest. This update adds proper key handlers for these keys, so they trigger appropriate events in the guest. In addition, sending keys for controlling guest audio over VNC or SPICE now works as expected.

Comment 7 Guo, Zhiyi 2017-12-14 07:31:17 UTC 
Reproduce this issue with qemu-kvm-rhev-2.9.0-16.el7_4.5.x86_64, host & guest kernel 3.10.0-693.5.1.el7.x86_64.

qemu cli used:

My keyboards has volume up/volume down/audio next/audio previous/audio stop/audio play/mail/calculator/home keys

Steps:
1)Login to guest desktop, open gnome-terminal and run xev -event keyboard
2)press the keys I have
3)launch another gnome-terminal and run xinput test keyboard_id
4)repeat step 2)
Result:
After 2), no keyevents prompt. After 4), no events prompt.
Switch display to vnc, get same results as spice.

Test against qemu-kvm-rhev-2.10.0-11.el7.x86_64, after 2) xev will prompt some output, because of some keys have no function defined in gnome, just output. 
After 4), the outputs of keys are same after comparing the outputs between host and guest.
Switch display to vnc, I get same results.So bug is fixed
