Hi,

I'm new to xen and am having trouble getting my domU's networked.

My dom0 is connected to the outside world via eth1

I have a distinct /29 allocated to me which is routed to my eth1 IP
xxx.yyy.82.76

I tried to follow the example here:

http://www.debian-administration.org/articles/360

But that didn't work. I think my first problem was Xen trying to clone
the IP from eth0 - that's not going to work when it doesn't have an
IP.

I have set up a dummy0 interface as follows:

         inet addr:xxx.yyy.93.105  Bcast:xxx.yyy.93.111  Mask:255.255.255.248

I've changed /etc/xen/xend-config.sxp so it looks like:


 (xend-relocation-server yes)

 (xend-relocation-hosts-allow '^localhost$')

 (network-script network-route)
 (vif-script vif-route)

 (dom0-min-mem 1024)
 (dom0-cpus 0)

I also changed /etc/xen/scripts/vif-route so main_ip="xxx.yyy.93.105"

as the previous "main_ip=$(dom0_ip)" wwas preventing my domU's from
starting at all.

So, can anyone direct me where I need to look now to get my domU's up
and running with the public IPs I've had allocated.

Many thanks for any and all help offered!

Russell.
