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 of problem:
There are two APIs for querying information related to AMD SEV - virDomainGetLaunchSecurityInfo and virNodeGetSEVInfo.
Contrary to normal practice, neither of these is exposed as commands in virsh
This is unhelpful for users and applications using virsh to interact with SEV enabled guests, as well as for debugging/troubleshooting purposes.
These need to be exposed as 'domseclaunchinfo' and 'nodesevinfo' commands.

Fixed upstream by:
commit 719bb0bf23709bcbd007a65a9304dadd7e6bbeba
Author: Daniel P. Berrangé <berrange>
Date: Wed Dec 8 08:28:48 2021 -0500
tools: add 'nodesevinfo' virsh command
While some SEV info is reported in the domain capabilities,
for reasons of size, this excludes the certificates. The
nodesevinfo command provides the full set of information.
