Re: [Xen-devel] Odd Bridging Quirk

I am seeing an odd bridging quirk, on my domU instances.
When any of my domU's start, they cannot receive any traffic until they
have sent at least a few packets. Time seems to have no effect on this
behavior. If I let an idle domU sit for an hour, it still fails to
receive, if it has not originated any traffic.
My workaround for the moment, is an added rc-init script that pings the
default gateway a few times when the domain first comes up.
Is this normal? Should there be a warning in the docs, if it is? If not,
does anybody have any ideas what may be causing this?
I think I remember having this same problem when I set up networking
with Xen. How are your domains getting their network addresses? I
think the problem may have had something to do with ARP not being
correctly set up between the bridge, the DomU's, and the network, such
that a domain needed to send some packets out before it was known to
have a given address.
