With a NetBSD DomU and Xen 3.0.4-1, the assignment is comparable to a
slot machine. The oddest part is that this DomU is meant to be my
gateway, if I ever figure this out.

vif = [ 'vifname=peru1, mac=00:16:3e:c3:c3:c1, bridge=xenbr1', \
'vifname=peru2, mac=00:16:3e:c3:c3:c2, bridge=xenbr2' ]

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.
