[one-users] Does anyone have run Ubuntu instance in OpenNebula successfully ?

[Jaime Melis]

Hello,

Indeed the classic approach of installing manually an Ubuntu 10.04 VM under
KVM and launching it with OpenNebula is a bit tricky since it has problems
booting up. We have used and alternative method to prepare VMs which works
perfectly with Ubuntu 10.04:

- Create an OpenNebula template with 2 DISKs:
<<<<
DISK = [
    source = "/path/to/ubuntu-10.04.2-server-amd64.iso",
    type    = "cdrom",
    target  = "hdc"
]

DISK = [ TYPE   = fs,
         SIZE   = 10240,
         FORMAT = ext3,
         SAVE   = yes,
         TARGET = sda ]
>>>>
- Define the VNC attribute, and OS = [BOOT = "cdrom" ]
- Launch the VM with OpenNebula
- Connect to the running VM with VNC and install Ubuntu. (It comes in really
handy here to have a DHCP server for the installation).
- Manually partition: a single partition mounted on / without swap.
- Install OpenSSH server during installation
- Before shutting down the VM, execute "onevm saveas <VM_ID> <DISK_ID>
<new_image_name>" DISK_ID should be '0'.

The saved image should now boot without further trouble.

Regarding Contextualization:
- for net-contexutalization: a very easy and straight-forward way to
contextualize is to disable automatic configuration of eth0 in
/etc/network/interfaces and adding this [1] script to /etc/rc.local
- don't forget to install acpid package
- follow OpenNebula's guide on contextualization for full contextualization
[2]

We are preparing a blog post explaining this more thoroughly and we will
link to a contextualized Ubuntu 10.04 prepared by us. It should be ready by
next week.
