But given the place in the network-bridge scrpit where you say it is failing,
the tmpbridge device has not been brought up yet, so I've no clue how it
got into that state.
As a nasty hack you can try changing op_start method from
ip link set ${netdev} name ${pdev}
ip link set ${tdev} name ${bridge}
To
ip link set ${netdev} name ${pdev}
ip link set ${tdev} link down
ip link set ${tdev} name ${bridge}
But I'd really like to know why it was in the UP state at all. So it'd
be useful if you could edit op_start and put in a call 'ifconfig ${tdev}'
and "echo doing stage ...blah..." in between every step in op_start() to
see just where it gets into the UP state
Dan.
I disabled libvirtd in the runlevel to get rid of the virbr0 device and
rebooted. The result is shown in the *.before files.
I changed the lines in op_start as you said:
op_start () {
...
# ip link set ${netdev} name ${pdev}
# ip link set ${tdev} name ${bridge}
ip link set ${netdev} name ${pdev}
ip link set ${tdev} link down
ip link set ${tdev} name ${bridge}
...
A /etc/init.d/xend start results in the *.after files.
Debugging the code results in:
[root@scp-156 ~]# /etc/xen/scripts/network-bridge start
stage 1
tmpbridge: error fetching interface information: Device not found
Attached you will find the code block of op_start{}
