Open Stack

Hi,

After some more tests i was able to link the failure of the jenkins job
with the errors in dmesg :

Job failed at ~ 11:08.

All VMs (the devstack slave) are connected to br100
Jenkins master uses vnet0 but the public ip is manually added to br100 and
NATed using iptables while the devstack vm uses vnet1 (which is bridged
with eth0).
