Hi all,
I have a domU with three interfaces using a bridged setup, but the
packages seem to arrice randomly on the interfaces in domU.
dom0 and domU are Ubuntu 6.10.
domU.cfg:
...
vif = [
''ip=88.198.X.A,bridge=xenbr0'',''ip=88.198.X.B,bridge=xenbr0'',''ip=88.198.X.C,bridge=xenbr0''
]
...
domU log generated by iptables:

domU /etc/network/interfaces:
auto lo
iface lo inet loopback
# device: eth0
auto eth0
iface eth0 inet static
address 88.198.X.A

netmask 255.255.255.248
gateway 88.198.Y.Y
# device: eth1

broadcast 88.198.Y.Y
netmask 255.255.255.248
gateway 88.198.Y.Y
# device: eth2
auto eth2
iface eth2 inet static
address 88.198.X.C
broadcast 88.198.Y.Y
netmask 255.255.255.248
gateway 88.198.Y.Y
---
Why isn''t eth0 used at all in domU?

Remove the gateway entries for eth1 and eth2 and see if that improves your situation. jez _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I had the same problem. I don''t know how debian/ubuntu handles it, but my solution under CentOS involved setting the mac addresses in the domU.cfg, and then matching those mac addresses in the interface config files. That way even if the interfaces are initialized in a different order, they still end up going to the right bridges. Also, does debian really allow multiple gateways? RHEL doesn''t, but it didn''t matter to me since the other bridges were private networks.
