Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Comment 1 Markus Armbruster 2015-11-20 08:16:05 UTC
In order to have full forward compatibility support, QMP needs to be capable of
describing itself.

This means that we need commands to dump the following protocol information:

o Accepted commands, arguments, responses and errors
o Asynchronous messages and their data
o Protocol capabilities
o Errors

The work has now landed upstream (commit 39a1815 "qapi: New QMP
command query-qmp-schema for QMP introspection" and commit 1a9a507
"qapi-introspect: Hide type names") and will be in 2.5.

This bug is for tracking a possible backport to qemu-kvm.

Comment 3 Markus Armbruster 2015-11-30 09:14:51 UTC
No doc text needed, because direct use of QMP isn't supported.

Comment 4 Markus Armbruster 2016-07-22 07:38:00 UTC
A backport will be non-trivial.  It should only be undertaken if there's actual demand.  As long as there isn't, we'll keep punting this bug.
