Hi Javi,
My first guess would be that the network interface in the VM has problems. You
can confirm this by starting the VM with VNC enabled. If it comes up alright
log in through VNC and check the network interface connection.
Hard to guess what went wrong, but one thing you might want to look at: Some
Linux distros (and I don't know if ttylinux is one of them) keep track of what
network cards they have seen (identifying them by their MAC address). The first
time a network card is found, it is bound to a network device, e.g. eth0. If
Linux then finds a network card with a different MAC address it assigns it to a
different device, e.g. eth1. It does so even if the first card is not present
(as it interprets this scenario as "a second card has been added to the machine
and the first one is currently (temporarily) disabled"; which with real network
cards that don't change their MAC address is the most likely scenario). Now,
this does not work well with OpenNebula as the VM is likely to get a different
MAC address for each launch; this will be assigned to a new network device and
your /etc/network/interfaces file probably only includes a configuration for
eth0 (which does not exist). If this turns out
to be the case, there is a setting in Linux to prevent it from remembering
cards. I forgot what exactly it is, but it should be easy to Google.

Subject: [one-users] onevm saveas problem
Hi,
I'm using OpenNebula 2.0 and I'm trying to save a VM with the "onevm
saveas" command. The VM is the ttylinux provided by you as example and
the only modification that I've made is create a file. The problem is
that when I start the saved VM (with the same parameters except the
Image name) I can't access it using ssh. If I execute "onevm show
<id>", Its status is "runn" and it has an private IP address assigned.
Any idea what is happening?
Thanks you in advance.
Regards,
Javi
