/sys/class/net/xenbr5/bridge: No such file or directory

[Jon R.]

I followed Pasi's setup at 
http://wiki.xensource.com/xenwiki/RHEL6Xen4Tutorial to configure and a 
SL6 box. This all worked great and I have a working system. When I look 
at my bridge with 'brctl show' I am seeing this as the output:

brctl show
bridge name    bridge id        STP enabled    interfaces
xenbr5        /sys/class/net/xenbr5/bridge: No such file or directory

The files are in the system as 'ls -l' shows:

I am bonding my interface eth0 and eth1 and assinging the bridge to the 
bond, here are my ifcfg scripts:

I read through this post,  
http://permalink.gmane.org/gmane.comp.emulators.xen.devel/98821, and it 
never did give an answer to what may be causing this. Is this something 
that can be ignored?


Thanks for any help,

I found the answer to this issue in a thread on the xen-users list, John Haxby explains
the issue here:

http://lists.xensource.com/archives/html/xen-devel/2011-02/msg00760.html

What I did was download this rpm:

bridge-utils-1.2-9.fc13.x86_64.rpm

And did an rpm -Uvh and now I am seeing this on a 'brctl show' command:

 brctl show
bridge name     bridge id               STP enabled     interfaces
xenbr3          8000.001125a5ce44       no              bond0.3
xenbr5          8000.001125a5ce44       no              bond0.5

Pasi, you might want to look into this on your tutorial,
http://wiki.xen.org/xenwiki/RHEL6Xen4Tutorial or mention what causes the
"/sys/class/net/<BridgeName>/bridge: No such file or directory" error to
appear on a 'brctl show'.

While my system still worked with the errors with no issues, the output was ugly to have
to look at. :)

Hope that helps someone else,

Jon

Thanks. Do you have an account on Xen wiki? You could edit/add yourself :)

Hi Pasi,

I do not have an account on the wiki and wasn't sure if this would be the preferred
method of fixing the issue or if patching the RHEL6 bridge-utils package to remove the
IGMP_snooping_support and rebuild the rpm would be better. I would think that just using
the Fedora binary would suffice for now seeing as how close we are to being able to use a
kernel.org kernel and I believe with that kernel this issue will disappear.

So I leave that up to you to decide which method you prefer. :)

And thanks for the great RHEL6Xen4Tutorial it was incredibly easy to follow!!
