Re: [Xen-users] order of network interfaces in domU messed up?

[Sven Giermann <giermann@xxxxxxxx>]

Hi Sven,

I can confirm the re-ordering after upgrade to Xen 3.0.4!
Unfortunately it is not really this easy and I agree, that it looks very
random...

I have 3 interfaces in my Xen-Config:

vif = [ 'mac=00:16:3e:01:00:12, bridge=xenbr0',
        'mac=00:17:3e:01:00:12, bridge=xenbr1',
        'mac=00:18:3e:01:00:12, bridge=xenbr1' ]

And since Xen 3.0.4 I get the following order in DomU:

# ip addr
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000
    link/ether 00:16:3e:01:00:12 brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000
    link/ether 00:18:3e:01:00:12 brd ff:ff:ff:ff:ff:ff
4: eth2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000
    link/ether 00:17:3e:01:00:12 brd ff:ff:ff:ff:ff:ff


Anyone with better experience in vif ordering to help us?

Sven.
