For VNC-Access I have to put the following into "ubuntu.one"?<br>
<pre class="code">GRAPHICS = [
type = "<span class="search_hit">vnc</span>",
listen = "1.2.3.4",
port = "5902" ]

</pre>
And btw: is there a possibility to change "ubuntu.one" without doing
a resubmit? Because this takes about ten minutes and slows down my
PC.<br>
In other words, I'm searching for a way to use the image again that
already has been copied via ssh....<br>

<pre wrap="">Your VM configuration seems to be ok. Can you check that your machine
has a route to access 192.168.122.0/24 associated to virbr0?
Alternatively try to access the machine using VNC. Maybe there is a
problem with the machine and is unable to start.

I've just tested the ubuntu image and gets the IP selected by
OpenNebula. It also configures the root authorized_keys wth
SSH_PUBLIC_KEY parameter in context. Can you send us the template used
to create the VM?

Thank you!
I will try it, but why is ttylinux working when virbr0 isn't associated
with any physical interface?
Am 21.01.2013 12:10, schrieb Javier Fontan:
virbr0 is a bridge automatically created by libvirt and is not
associated to any physical interface (vnet0 is not a physical
interface). You should create a new bridge or associate a physical
interface to virbr0. I think it is better to create a new one. If you
are using ubuntu you can find more information in these two guides:

Can you check that virbr0 bridge is associated to a physical
interface? You can use "brctl show" to get that info.

Hello,
I'm trying to get the ubuntu image from the marketplace running, but
the
VM
doesn't seem to get an IP.
(I don't get another IP in this net even if I scan with nmap.)
This is my virtual net:
oneadmin@Arbeitsrechner:~/one-templates$ ifconfig virbr0

This is the template for "onevnet create small_network.net":
oneadmin@Arbeitsrechner:~/one-templates$ cat network/small_network.net
NAME = "public"
TYPE = FIXED
BRIDGE = virbr0
LEASES = [ IP="192.168.122.5"]

NETWORK_MASK=255.255.255.0
GATEWAY=192.168.122.1

And finally this is the template for "onevm create ubuntu.one"
oneadmin@Arbeitsrechner:~/one-templates$ cat ubuntu.one
