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: On 1/10/08, Jeffrey Ollie <jeff@xxxxxxxxxx> wrote: > On 1/10/08, Code Monkey <have.an.email@xxxxxxxxx> wrote: > > > > I have quagga on some servers, I have Xen on some servers, now I want > > to run quagga on the Xen dom0 to distribute the domU addresses. > > > > I copied configs from quaggas running elsewhere, and I don't > > understand why quagga is saying that my eth0 is down! > > > > There is one domU running for the moment, but I'm not trying to do > > OSPF with the domUs, just between the dom0 and the cisco router. > > This is probably because "eth0" is no longer a direct reference to > your Ethernet hardware under Xen.

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!
