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.

@bfu : FYI, I've now written a patch that adds some documentation, but it's added to the /usr/share/doc/qemu-kvm/system/s390x/bootdevices.html documentation, not to the man page ... I hope that's also OK? (It made more sense to me to add it to the place where we document the behavior of the boot on s390x)

qemu version: qemu-kvm-6.2.0-26.module+el8.8.0+17341+68372c23.s390x

Test result:
[root@s390x-kvm-009 ~]# /usr/libexec/qemu-kvm -machine s390-ccw-virtio,? | grep -i loadparm
  loadparm=<loadparm>    - Up to 8 chars in set of [A-Za-z0-9. ] (lower case chars converted to upper case) to pass to machine loader, boot manager, and guest kernel


Follow the test result, set this bz as verified
