[Fiware-lab-help] Networking problems in the Spain node

Good afternoon,

I write to report some problems I have using que FiWare Lab platform. My
name is Sergio García (sgarcia in FiWare Lab) and I work in Atos. I
created some small infrastructure but, since Tuesday I can not access
them due to (I think) network problems.

The details are the following. I uploaded my key to connect to the VMs
and assigned it to a security group. I set up three virtual machines of
the "small" flavor running a public Debian image in the Spain node and I
assigned the security group I pointed before to them. At last, I
assigned the only floating IP I have available to one of these VMs in
the security group and I opened the proper ports (22 and 8080). In that
way, I was able to connect to the VM through ssh and set up some
services (like a Jenkins instance). Suddenly, this last Tuesday, between
13 and 14 I realized that I was not able to connect to any service of
the virtual machine (both SSH or Jenkins, for example).

Although I am able to use the FiWare Lab platform through the web, I am
not able to connect to new VMs. When I create an instance, I can see all
the booting process in the "Log" tab. What I see there is that the OS is
trying to set up a network but it can not. After several tries, it gives
up and finishes the boot process without any available network. I have
tried with several images and operating systems, with the same result.

I attach a screenshot of the Fiware Lab VNC view of a try running an
Ubuntu 14.04. As you can see, the network can not be set.

Kind regards,
