Thread-topic: Bridged networking not working as expected
Hello list,

I am trying to connect 16 machines. I changed the loopback-values to

If i now start all machines and try networking, about the half couldn't
connect the internet but get an IP and can ping the dom0. So i decided
to seperate them into 4 bridges, so vm 0-3 are on bridge "cluster0", 4-7
are on "cluster1" and so on...

For that, i changed my xend-config.sxp:
#(network-script network-bridge)
(network-script network-bridge bridge=cluster0 vifnum=0)
(network-script network-bridge bridge=cluster1 vifnum=1)
(network-script network-bridge bridge=cluster2 vifnum=2)
(network-script network-bridge bridge=cluster3 vifnum=3)

But this didn't work. Restart of xend did no error-messages, but neither
did install four bridges. If i add "bridge=cluster0" to a virtual
machine and start it, i get the error that the bridge is missing.

So there are two main questions for me:

1. WHY is bridged networking only working for half of the vms'?
2. What's the fault in my "bridge-multiply"-config?

Kind regards, Florian
