Hello Everyone,
Hello,
I found this link OpenNebula Ubuntu 14.04 Quickstart
http://docs.opennebula.org/4.6/design_and_installation/quick_starts/qs_ubuntu_kvm.html
to install open nebula on Ubuntu 14.04,
Note that the current stable OpenNebula[1] is 4.10.
This includes the frontend and how to add nodes. My question is
according to this article, I can install OpenNebula frontend right on
the Ubuntu Server with the KVM install, is this correct?
Also is it possible to have just the frontend installed by itself (non-kvm
server), then add nodes to it, I would prefer to it that way. If it is
possible is there a step by step document for me to use to help me through
the process?
This article describes a multi-server setup:
- the frontend which runs the management daemons, the opennebula web
interface (sunstone) and a NFS server
- the nodes which run libvirtd and use the NFS exported by the frontend
In the NFS configuration[2], you have a warning about setting up what I
call a « single node », i.e. everything on a single physical standalone
machine.
Some steps are already managed by the opennebula debian packages, like
the Qemu configuration.
The minimal requirement for a separated frontend is the ability for the
user oneadmin on the frontend to connect over SSH on each nodes without
passwords.
If you want live migration, you must use shared storage[3][4].
More informations are available in “planning the installation”[5].
Regards.

start but /var/lib/one/datastores.
