[Xen-users] Networking change in Xen unstable

[Takeshi Sone <ts1@xxxxxxxxx>]

Hello,

I'm now using Xen unstable, which works very nice.
For me it's generally more stable than 2.0 (no FPU problem now).

I have noticed that veth0 and vif0.0 appear in net devices,
and veth0 is attached to xen-br0. Routing to the bridge network is 
now through veth0, instead of xen-br0 like it used to be.

The problem is, my iptables configuration (on dom0) complains
with this setup. This message appears in kernel log (dmesg):

    Performing cross-bridge DNAT requires IP forwarding to be enabled

I'm DNATting DNS requests from Internet to domU, and it doesn't work.

Killing veth0 and assigning IP address to xen-br0 fix this problem:

    # ifconfig veth0 0.0.0.0
    # ifconfig xen-br0 10.1.1.1 netmask 255.255.255.0

Frontend net device is disabled in dom0 kernel .config.

Could someone explain what is veth0 and its purpose?

Thanks,

Takeshi
