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.

Comment 8 weizhang 2010-08-02 08:24:01 UTC

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.
