Hello,
I have installed XEN 3.0 on a well-configured Ubuntu system, from
source. The process went well. The machine has one PCI ethernet card.
Now my problem is that when I boot the XEN machine, the domU domains do
not ping each other nor see the outside world. However, dom0 reaches the
outer world but not the inner domains. After booting, launching xend and
starting a VM, it seems to me that the bridge becomes peth0 that does
not its work. I am using a simple bridge to connext the VMs with each
one having a static IP.
If someone could shed some light on this, I'd be grateful!
thanks
Armand
(sorry for the long post)

Config: dom0 has the following network parameters:
$cat /etc/network/interfaces
mapping hotplug
script grep
map eth0
iface eth0 inet static
address 132.166.133.218
netmask 255.255.252.0
network 132.166.132.0
broadcast 132.166.135.255
gateway 132.166.135.254
# dns-* options are implemented by the resolvconf package, if
installed
dns-nameservers 132.166.192.7
dns-search ...
VM1 of domU is started with the following config :
kernel = "/boot/vmlinuz-2.6.12-xenU"
memory = 64
name = "VM%d" % vmid
cpu = vmid
vcpus = 1
nics=1
vif = [ 'mac=aa:00:00:00:00:11, bridge=xenbr0' ]
disk = [ 'file:/boot/VM/vm1disk,hda1,w' ]
netmask="255.255.252.0"
gateway="132.166.135.254"
root = "/dev/hda1 ro"
Note that virtual file systems are used by each VM.
Now the network config at 3 different steps:
