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.

Red Hat Product Errata RHBA-2011:1783 0 normal SHIPPED_LIVE rhev-hypervisor6 bug fix and enhancement update 2011-12-06 15:10:54 UTC

Description Perry Myers 2011-04-25 19:11:12 UTC 
Description of problem:
Several services fail on startup of RHEVH which produces red FAILED messages that appear on the screen briefly.  This might be alarming to customers so we should remove these.
Comment 1 Perry Myers 2011-04-25 19:12:41 UTC 
Services to check are:
* lvm stuff: ioctl reload failed, create reload failed
* cgconfig service
* ntpdate
Comment 2 Perry Myers 2011-04-25 19:14:04 UTC 
Also, we should add the quiet boot option to silence kernel messages to clean up the boot.
Comment 5 Alan Pevec 2011-08-05 22:14:34 UTC 
With default boot parameters "quiet rhgb" plymouth is masking initscript output, is there anything left for this bug?
Comment 6 Perry Myers 2011-08-06 14:27:41 UTC 
If you hit the arrow keys on the keyboard to leave the rhgb and go back to the normal initscript view of the boot, are there error messages still displaying?  We have to assume some users will do this, and also won't initscript results show by default on serial console instead of rhgb?

This is a 'nice to have' though, certainly not critical so pending time take a look at it, or push off to next release if there is no time.
Comment 7 Alan Pevec 2011-08-08 08:51:42 UTC 
bug 675868 is covering startup messages due to R/O rootfs
this one is making boot quiet by default on the default console and users on the serial console are hopefully not faint of heart.

> * ntpdate

bug 675870

> * cgconfig service

# service cgconfig start
Starting cgconfig service: Loading configuration file /etc/cgconfig.conf failed
Cgroup, operation not allowed
Failed to parse /etc/cgconfig.conf[FAILED]
But /etc/cgconfig.conf is original from RPM.
We could also disable cgconfig on RHEV-H for now, vdsmd has it listed in CONFLICTING_SERVICES due to bug 623712

Not in Beta3 based on 6.2 kernel which has 623712 fixed.
Comment 10 Alan Pevec 2011-09-09 11:26:01 UTC 
Root cause:
/sbin/cgconfigparser -l /etc/cgconfig.conf
mkdir("/cgroup/cpuset", 0775)           = -1 EROFS (Read-only file system)

/cgroup needs to be added to rwtab

cgroups is still not used by vdsm in RHEV 3.0 Beta 3 due to bug 742414
cgconfig service will be disabled in RHEV-H to avoid side-effect bug 703095 comment 20
Comment 20 Alan Pevec 2011-10-18 19:57:09 UTC 
Bug 742414 is targeting Snapshot 3 so we can re-enable cgconfig again
Comment 22 Mohua Li 2011-11-08 07:47:15 UTC
