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.

Doc Type: Bug Fix
Doc Text:
* The Red Hat Enterprise Linux guest image did not make use of the ttyS0 serial port by default, so tools that monitor the serial console log did not capture any information. This update adds a console log feature to the boot loader, and the Red Hat Enterprise Linux guest image will now print boot messages on the ttyS0 serial port and the standard console.

Description Giulio Fidente 2013-05-31 14:15:08 UTC 
Description of problem:
openstack provides a "nova console-log" command which captures the messages sent to ttyS0; rhel images don't make use of ttyS0 by default so the console log seems to be empty


Version-Release number of selected component (if applicable):
rhel-server-x86_64-kvm-6.4_20130130.0-4.qcow2


Steps to Reproduce:
1. launch a rhel instance
2. check the console log

Hi Joey,
  After you apply this patch, i can use virsh console to connect to our applance, but this is still something abnormal.

  The getty prompt appears earlier than the other bootup messages, if i type username at this time, i'll give me the bash session, but after all services is booted, there will have another getty prompt, which will interrupt with the earlier one, which make everything messed up.

  The way to workaround such problem is interact with getty prompt after all services launched.

  We can watch the system booting messages through 'virsh console' and login to the appliance after getty apears and interact with the shell.
