Hi,
Quagga refuses to recognize my eth0 interface that seems to work
perfectly otherwise. Sentiment on quagga list seems to be that this is
a Xen problem, so here is my problem:

This is a Debian etch system, other information below.
Linux ${hostname} 2.6.18-5-xen-686 #1 SMP Mon Dec 24 20:49:58 UTC 2007
i686 GNU/Linux
I don't want to use bridges, I want quagga to advertise the /32s of my domUs.
# grep -v '^#' /etc/xen/xend-config.sxp | grep .
(network-script network-route)
(vif-script vif-route)
(dom0-min-mem 128)
(dom0-cpus 0)
I tried peth0, exact same thing. Nowhere on the machine have I found a
reference to anything else than eth0 (ifconfig, /proc/net/dev...)
where should I look?
Thanks for any help!
