Description: Ubuntu 12.04.2 LTS
Release: 12.04
Running this kernel after a recent update.
Linux ibmlaptop 3.2.0-41-generic #66-Ubuntu SMP Thu Apr 25 03:27:11 UTC 2013
x86_64 x86_64 x86_64 GNU/Linux
After upgrading, kvm can't start my VM that uses bridging. Tracked it
down as noted below:
WHAT I DID:
I did a sudo depmod /lib/modules/3.2.0-41-generic/kernel/net/bridge/bridge.ko
(this appears to succeed - no messages and 0 exit code)
and a $ sudo insmod /lib/modules/3.2.0-41-generic/kernel/net/bridge/bridge.ko
WHAT I EXPECTED:
I expected the bridge module to load.
WHAT I GOT:
insmod: error inserting
'/lib/modules/3.2.0-41-generic/kernel/net/bridge/bridge.ko': -1 Unknown symbol
in module
Looking at the syslog, I got the unknown symbol messages below:
May 9 17:38:30 ibmlaptop kernel: [ 6162.081081] bridge: Unknown symbol
stp_proto_register (err 0)
May 9 17:38:30 ibmlaptop kernel: [ 6162.081143] bridge: Unknown symbol
stp_proto_unregister (err 0)
what started me down this path:
WHAT I DID:
Started a virtual machine with bridging enabled using Virtual Machine Manager
WHAT I GOT:
Error starting domain: Cannot get interface MTU on 'br0': No such device
Details:
Error starting domain: Cannot get interface MTU on 'br0': No such device
Traceback (most recent call last):

if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: Cannot get interface MTU on 'br0': No such device
WHAT I EXPECTED:
For the VM to start like it did before the upgrade.
All the things above came from further investigation of this problem.
Uncertain if this is related, but , there appear to be a lot of broken
symbols in this kernel:
