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 IBM Bug Proxy 2010-09-13 19:43:05 UTC

1. Feature Overview:
Feature Id: [67041]
a. Name of Feature: [6.1 FEAT] Enhance installer to support installation using HVC terminals over IUCV
b. Feature Description
The distribution installation can benefit from the full-screen terminal capabilities
and the independence of IUCV from TCP/IP networks. The terminal server over IUCV (already included
in existing distributions) consists of a kernel driver that provides HVC terminal devices which can
be connect to. It also provides the necessary tools and programs to establish connections. The
terminal connections are based on z/VM IUCV (Inter-User Communication Vehicle) that provides
in-memory communication between two z/VM guest virtual machines. The HVC terminal devices are
standard Linux terminal devices and are a full-screen alternative to traditional mainframe
terminals, for example, 3215 line-mode and 3270 block-mode terminals. This feature requests
enhancing the installer to support HVC terminal devices for installation, to increase usability
during the first installer phases.

Notes:
- Design for this feature will be developed in corporation between Distributor
installer team and IBM development (with focus for future enhancements
for terminal functions).
- Design and initial prototype might be developed by IBM internally.

Code Upstream Status: No Code Required

Comment 3 John Jarvis 2010-11-19 14:10:54 UTC

This feature needs to be implemented in Fedora first and then considered for
backport to RHEL.  Given where the schedules are and the other work committed
to for 6.1, development management does not see this making it in time.  Moving
to the 6.2 planning list.

------- Comment From mgrf.com 2010-12-13 12:19 EDT-------
Accept the reject for R 6.1 - will request for R 6.2 again

Comment 8 Dave Cantrell 2011-05-23 19:41:11 UTC

New and extended product functionality as well as new features for this component must be implemented by IBM and accepted upstream before consideration for a RHEL backport can be made.  For your convenience, this bug has been cloned to the same component under Fedora, which serves as the upstream development area for RHEL.

Comment 9 RHEL Program Management 2011-05-23 19:55:43 UTC

Development Management has reviewed and declined this request.  You may appeal
this decision by reopening this request.

Comment 10 Georg Markgraf 2011-06-08 10:26:23 UTC

Appeal this decision -> re-open this request

Comment 11 Dave Cantrell 2011-06-08 15:14:05 UTC

See comment #8.  Bug #707036 exists to track the upstream contributions for this feature request.

Comment 12 Georg Markgraf 2011-06-10 15:00:13 UTC

The Installer is the value-added code from Red Hat.
  - Red Hat have to maintain this differentiator for RHEL
  - System z cannot take ownership for the installer
For sure System z will offer help like in the past. 

If you want to track this via Fedora - fine but that makes no difference 

Although its obvious I re-call
  - it is very important that the installer get improved for our customers

Comment 13 IBM Bug Proxy 2011-08-24 19:31:54 UTC

------- Comment From mgrf.com 2011-08-24 15:24 EDT-------
Per discussion with John
I assign this feature to the RHEL 6.3 tracking list
This also get discussed in Fedora via ticket 707036

The process of mirroring from/to Fedora is actually in discussion
1) assign this feature BZ to the Fedora ticket
when Fedora is resolved re-assign to R 6.3
2) create reverse mirror of the Fedora ticket and have parallel tracking

Comment 14 John Jarvis 2011-08-24 19:43:02 UTC

Just so we are clear, the Fedora version of this feature is waiting on IBM code contribution and activity and will make no progress without this.  This 6.3 BZ is set as being dependent on the Fedora BZ and so this feature will make no progress without active IBM engagement on the Fedora BZ.

Comment 15 John Jarvis 2011-09-15 19:17:13 UTC

Closing as NOTABUG.  This feature needs to be implemented in Fedora before it
will be consider for RHEL inclusion.
