Re: [Xen-users] Interface Order

Thanks for that information!

Do you have a customized vif-script as well?
It seems that your custom-bridge does the same I do in my "static  
(with /etc/network/interfaces in debian) configuration - I create  
bridges to "physical" interfaces:
iface br9 inet manual
        up brctl addbr br9
        up ip link set br9 up
        up brctl addif br9 vlan9
        down brctl delif br9 vlan9
        down ip link set br9 down
        down brctl delbr br9

iface vlan9 inet manual
        pre-up vconfig set_name_type  VLAN_PLUS_VID_NO_PAD
        pre-up vconfig add eth0 9
        pre-up ip link set vlan9 address 00:16:3e:09:01:01 arp off
        up ip link set vlan9 up
        down ip link set vlan9 down
        post-down vconfig rem vlan9


... and so on...
But I think that the vif-part is the "faulty" one.
