[one-users] Can not connect to VM

Hi all,

Trying to run OpenNebula for the first time, apologies for basic questions
in this mail.
I spent all the day looking at this problem without any success... I think I
have a problem in my network interface configuration but I am not sure...
So, I try to run the ttylinux example without any success. I am able to
create the new VM but I can not ping nor SSH it.
Can someone help me solving this issue?
Thanks a lot!

 Here are all the details:

My environment : libvirt/KVM on Debian 5 (In fact the Debian Node runs on
top of virtual box, I hope that it is not a problem).
The front is running on 192.168.2.60, I only have one node on 192.168.2.61.
On 192.168.2.61, I manually configured a bridge in /etc/network/interfaces
like this (I removed all the eth0 related parts...)
auto br0
iface br0 inet static
address 192.168.2.61
netmask 255.255.255.0
network 192.68.2.0
broadcast 192.168.2.255
gateway 192.168.2.1
bridge_ports eth0
bridge_stp off
#bridge_maxwait 0
bridge_fd 9
bridge_maxage 12
bridge_hello 2

Here are my TTYLinux configuration files, I put the bridge value to the one
defined just before :

debian-01:~/one-templates$ more small_network.net
NAME = "Small network"
TYPE = FIXED

#Now we'll use the cluster private network (physical)
BRIDGE = br0
LEASES = [ IP="192.168.2.71"]
#LEASES = [ IP="192.168.0.6"]
#LEASES = [ IP="192.168.0.7"]
