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 1 Qian Guo 2014-09-09 08:29:32 UTC

Clone this bug to qemu-kvm-rhev components since qemu-kvm-rhev-2.1.0-3.el7.x86_64 can reproduce this bug too,  and please refer to bug 1138228 comment 4 for more detail infos.

Deferring to 7.2
Not a real-life use case. Guests should not be stopped (like a stuck hardware).

Comment 4 jason wang 2015-02-02 08:05:51 UTC

Can QE try to see if it was still reproducible for recent qemu-kvm-rhev?

Thanks

Hi, Jason

Retest this bug with qemu-kvm-rhev-2.1.2-23.el7.x86_64, can not reproduce this bug, tried with following scenarios:

1.RHEL6.6 guest + right/wrong dst_mac

2.RHEL7.1 guest + right/wrong dst_mac

All works fine.

And can reproduce with qemu-kvm-rhev-2.1.0-5.el7.x86_64(just to confirm if the steps are right.) when pktgen tests with wrong dst_mac


So the latest build can fix this bug.
