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 Martin Kletzander 2013-04-11 14:13:08 UTC 
Could you try to reproduce that on virt-manager-0.9.5-1 (latest version at this point)?  Thanks.
Comment 3 hongming 2013-04-12 07:42:31 UTC 
I can't reproduce it using virt-manager-0.9.5-1.el7.noarch. but it is rhel7 version ,the bug is filed for rhel6. Do we need to clone the bug to rhel7 ?
Comment 4 Martin Kletzander 2013-05-28 15:34:04 UTC 
No need to clone, I just wanted to know whether it's fixed in newer version by any chance, thanks.  But working on this now, I can't reproduce it with virt-manager-0.9.0-18.el6.x86_64, could you try that with the '--debug' parameter and post the output here?  In the meantime, I'll try to downgrade here and reproduce it as well.  Thanks, Martin.
Comment 5 Martin Kletzander 2013-05-29 16:19:10 UTC 
Still works for me with all the versions.  I'll be able to do more with the log from the time it was reproduced.  Thanks.
Comment 6 hongming 2013-05-30 02:31:17 UTC 
Hi Martin 
I still can reproduce it in virt-manager-0.9.0-18.el6.x86_64 and virt-manager-0.9.0-15.el6.x86_64.

Detailed steps as follows

1.  create a bridge named br0.
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
BRIDGE=br0

# cat /etc/sysconfig/network-scripts/ifcfg-br0 
DEVICE=br0
TYPE=Bridge
BOOTPROTO=dhcp
ONBOOT=yes
DELAY=0

2. 
# service NetworkManager stop
# service network restart

3.
# service libvirtd restart

4.define a network via libvirt
# virsh net-dumpxml bridge-test
<network>
  <name>bridge-test</name>
  <uuid>2387ed67-23a4-47d4-8227-fa6b0f861760</uuid>
  <forward mode='bridge'/>
  <bridge name='br0' />
</network>

5. 
#service libvirtd restart 


6.virt-manager -> locahost connnection -> right-click "details" -> Select the "bridge-test"
