Mailing List Archive: network start loses the network

Since updating from unstable yesterday I'm losing the network
when xend starts. The culprit appears to be the 'network' script.
Details below. I just noticed that if I run 'network start' by hand
I get this error:

*network start bridge=xen-br0 netdev=eth0 antispoof=yes
iptables v1.2.7a: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

What version of iptables is needed now?

I also noticed that in xend-config.sxp I have
(vif-antispoof no)

But the message above shows 'antispoof=yes'. Something got broke.

Before it runs I have this:

I have observed the same thing, Mike. In fact, I just saw with in the
latest xen-unstable-src.tgz file, May 26 20:08. The problem is I cannot
recreate it consistently; sometimes it just seems to work.
