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.

Fixed In Version: vdsm-4.9.6-40.0
Doc Type: Bug Fix
Doc Text:
Previously, if the "port mirroring enable" action on a virtual machine failed, it remained configured in the VDSM. This patch corrects the error so that if enabling port mirroring fails it is properly reflected in the VDSM.

Description GenadiC 2012-10-18 10:27:32 UTC 
Description of problem:
If an action of "port mirroring enable" on VM fails for some reason, it is still configured on VDSM

How reproducible:
Always

Steps to Reproduce:
1. Install RHEVH with 20121005.0.rhev31.el6_3 version (in this version you couldn't enable port mirroring because of the BZ 867387)
2. Try to enable port mirroring
3. 
  
Actual results:
Action fails, but vdsClient 0 list shows you VM with port mirroring enabled 

Expected results:
vdsm shouldn't enable port mirroring as an action fails

Additional info:

vdsClient -s 0 list

> 2. Try to enable port mirroring

how do you do that? by starting a fresh vm with a target nic, or by hot-plugging?

(verification of this bug should be done for both means, btw)
Comment 3 GenadiC 2012-10-21 07:16:53 UTC 
In the specific scenario, that the logs are attached for I was using hotplug with port mirroring
Comment 4 Meni Yakove 2012-10-23 12:59:44 UTC 
When an action of hotplug fails because of port mirroring failure the engine report the hotplug is failed but on the host and also on the VM the new nic created.
When trying to start VM with port mirroring enable and if set port mirroring fails the VM will not start. 

Steps to Reproduce: (On rhel host)
1. mv /sbin/tc /sbin/tc.bak
2. Create VM and start it.
3. Add hotplug nic with port mirroring enabled.


Actual results:
Hotplug fail on backend but VDSM add the nic to the VM. 

Expected results:
Hotplug should fail.
