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.

Comment 2 RHEL Program Management 2010-07-20 17:38:04 UTC 
This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **
Comment 3 Andreas Rogge 2010-07-20 21:37:46 UTC 
I respect your decision, but please talk to the hardware vendors. The onboard NICs of every recent Dell PowerEdge will trigger this issue and I guess some more vendors will use OUIs that don't start with 00.

I guess it is resonable to expect this issue to happen with around 10% of all new servers.

But that's just my opinion :)
Comment 4 Alan Pevec 2010-07-21 00:10:35 UTC 
Please ignore comment 2 - that was bot talking :)
Requesting blocker flag.
Comment 6 Dave Allan 2010-07-21 15:47:55 UTC 
libvirt-0_8_1-17_el6 has been built in RHEL-6-candidate with the fix.

with startding new vm, the vnet0 show:

vnet0     Link encap:Ethernet  HWaddr FE:54:00:A3:44:D7  
          inet6 addr: fe80::fc54:ff:fea3:44d7/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:686 errors:0 dropped:0 overruns:0 frame:0
          TX packets:7564 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:500 
          RX bytes:180388 (176.1 KiB)  TX bytes:395489 (386.2 KiB)

so the bug is verified

libvirt-0.8.1-20.el6.x86_64
kernel 2.6.32-54.el6.x86_64
Comment 9 releng-rhel@redhat.com 2010-11-11 14:48:17 UTC 
Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
