Re: [Xen-users] Conflict with Xen bridge?
Hi,
as you can see, on brctl output there is only one virtual interface
vif0.0, on your xenbr0 bridge, and there isn't any physical interface.
I advice to put the following config:
copy/paste mistake :-(
bridge name bridge id STP enabled interfaces
xenbr0 8000.feffffffffff no vif0.0
peth1
I'd be consistent with the output of ifconfig which I put below in the
same e-mail :-)
humanum errarum est :)
About the wrapper script of network-bridge... I don't understand why it
don't work, try to execute it by hand
/etc/xen/scripts/network-bridge start bridge=xenbr0 vifnum=0
... and use brctl command to add, del interfaces and bridges...
Anyway, to debug the errors I will go step by step:
----Important-----:
Think that your config in /etc/network/interfaces your eth0 the pppoe interface
is vif0.0 in dom0 ! and your are attaching it to xenbr0 bridge with peth1 (eth1
physical interface)
Think about it, at the moment I don't have much time to give you a more detailed answer :(.
To do your scenario I will create 2 bridges and the via iptables make the FW ,
nat ...
Tell me about your progress, ;)

Create the following file:
/etc/xen/scripts/network-bridge-wrapper
give it permisions to be executable:
Put
#!/bin/sh
/etc/xen/scripts/network-bridge start bridge=xenbr0 vifnum=0
Change the following line in /etc/xen/xend-config.sxp:
(network-script 'network-bridge netdev=eth1')
for this line
(network-script network-bridge-wrapper)
After this restart your xend daemon, or reboot your box.
With this config a brctl show output may be:
sunfire:/home/xxxxxx# brctl show
bridge name bridge id STP enabled interfaces
xenbr0 8000.feffffffffff no vif0.0
peth0
I try this configuration, but I don't see up both peth and vif0.0
interfaces:
brctl show
bridge name bridge id STP enabled interfaces
xenbr0 8000.000000000000 no
cat /etc/xen/xend-config.sxp | grep ^[^#]
(network-script network-bridge-wrapper)

so... change the line in the file
/etc/xen/scripts/network-bridge-wrapper as your needs, also you can put
more lines to create more bridges, you can make very cool configs with
xen networking :)
I hope it will be useful.
Thanks for your reply.
Regards,
Daniel
