If you look on the VM host at the deployment.0 file
and the actual syntax of the kvm command that is being
called by libvirt, you should be able to figure out
what opennebula is trying to do.
What does the network section of your template say?
How is your onevnet configured?

Hi,
I have been working on it and I have "found" the problem. The thing is
that ONE is somehow changing the network interfaces of the VM
machines. When I register a VM image (oneimage register file.img) and
run it with KVM (kvm -hda ONE_LOCATION/var/image/imageId) it shows 2
interfaces (ifconfig -a): lo and eth1. But when I run the VM with
opennebula (onevm create template.one) with the same VM image as
before, it shows lo and eth2, and I have no clue about this behaviour.
To solve this is changed the image, so before registering it I
modified the /etc/network/interfaces to configure eth2 interface
instead of the real eth1 interface of the image. Now I can use my VM
machines, but this is not a good solution, and I hope I can find (or
someone else) a better one. I don't know if this could be considered
as a bug or it is just a configuration problem.

Same problem for me. I can run a Ubuntu image, but i cannot access it
with ssh or even ping to it. I can access it by using virt-manager,
and it is running ok, but the network interfaces are down and their
name change every time I run a new image (eth1, eth2, ...), so I can't
configure it.
Thanks you in advance.

Hello, Guys:
Currently I am doing some experiments with Opennebula, which is a
cloud management platform.
I have two computers, one is opennebula management node (Ubuntu Desktop 10.10);
the other one is opennebula worker node (Ubuntu Desktop 10.10 + KVM).
From the Opennebula website, I downloaded a ttylinux image, which is
contextualised for opennebula. From the opennebula management node, I
deployed this image to a VM running on the opennebula worker node
using "onevm create ...." command. This VM is successfully running
with an IP address. I can login to this tty VM.
However, I created a Ubuntu 10.10 Desktop Image by virt manger (virt-manager).
I tried to deploy it using the ubuntu script from the
/share/scripts/ubuntu/context, but I commented out CONTEXT part. I got
a running VM without IP address, I couldn't login to it and can do
nothing but see it's running.....
Or any of you know where I can download pre-built images....ttylinux
is just not enough....
Any help will be appreciated. Thanks.
