Description Adam Tkac 2008-03-25 08:53:38 EDT
Description of problem:
When I want create guest with bridged network interface "Network device" field
is gray (peth0 not bridged) but peth0 is network bridge

Version-Release number of selected component (if applicable):
$rpm -q virt-manager libvirt

How reproducible:

Steps to Reproduce:
1. setup network bridge through /etc/sysconfig/network-scripts/ifcfg-{peth0,eth0}
2. try create guest with bridged networking

Actual results:
Device field is gray and tells that peth0 is not bridged

Expected results:
not gray device

Additional info:
I'm using same configuration long time and this became broken during last month
(I'm able to find when exactly).

$ /usr/sbin/brctl show
bridge name	bridge id		STP enabled	interfaces
peth0		8000.00188b2be4d9	no		eth0

When I run guest which was created some time ago networking works as expected
(I'm able to ping guest from outside). Let me know if you need more info
(network configuration etc)

Hi, can you attach ~/.virt-manager/virt-manager.log? Thanks.
Comment 2 Adam Tkac 2008-04-02 04:53:00 EDT
It is nothing interesting there:
[St, 02 led 2008 13:25:10 virt-manager 16569] INFO (virt-manager:125)
Application startup
[St, 02 led 2008 13:25:11 virt-manager 16570] DEBUG (engine:69) About to connect
to uris []

It might be libvirt problem but I'm not able to track where exactly problem is.
Any hints how get more useful debug information?
Comment 3 Daniel Berrange 2008-04-02 07:54:01 EDT
There should be much more than that - please make sure you are connected to a
hypervisor and have the new VM wizard open. Then capture the logfile & attach
the whole file to this ticket.

In previous attempt I looked into my home dir instead /root.
Comment 5 Daniel Berrange 2008-04-02 10:58:39 EDT
Can you attach the output of these commands:

  ls /sys/class/net/*/*
  ifconfig -a
  brctl show

and also tell me what kernel you are running

Argggg - original comment didn't attach!

We are running into the same problem - we have two bridged networks, xenbr0 and
xenbr1 - these are not being displayed correctly (or at all) in virt-manager, as
you can see from the screenshot in the previous comment.


I will attach brctl, virt-manager.log and ifconfig -a output

After more investigation and some configuration hacking it works again, closing.
