[one-users] Cannot connect to VM

Hi Christophe,

I've tried to prepare that image for OpenNebula, but I haven't been
able to create the necessary scripts, since it lacks some basic tools
I need, for example 'grep'. It's a very minimalistic linux distro!

Creating an VM image is actually quite simple, and there are many
different procedures. Many people use redhat's utility: virt-manager,
but I don't have much experience with it, so I will just point you to
its documentation [1][2]

What I generally do is install the virtual machine locally in KVM. You
can do the same thing with other hypervisors, for example VirtualBox
or VMWare and later convert the created image to RAW format (note that
converting VMWare images to raw is a bit tricky). With VirtualBox you
can use VBoxManage to convert it to RAW [3].

Another important tip when using Xen is to install VMs with similar
kernel versions. That will make the process of editing/creating the
ramdisk easier [4].

Once you have installed the VM, it's time to prepare it for
OpenNebula. We call this process "contextualization" [5]. There are
two types of contextualization: network and generic

## Network Contextualization (or vmcontext) ##

OpenNebula tells the hypervisor what MAC address each virtual network
interface should have. This MAC address is obtained from the IP value
OpenNebula has assigned to it using the following algorithm: the MAC
address is the IP address expressed in hexadecimal preceded by the two
first bytes defined in oned.conf (MAC_PREFFIX).

So for instance if MAC_PREFFIX = 02:00 (default value) then:
192.168.0.10 => 02:00:C0:A8:00:0A

We can take advantage of this during the boot up process in the
following way: the VM should run a script which obtains the
corresponding IP address based on its own MAC address. A very simple
example of this script would be:

------------------------------------------------------------------------
#!/bin/sh

# get mac address
MAC=`ifconfig eth0|grep HWaddr|awk '{print $5}'`

# convert to hexadecimal
for i in `echo $MAC|cut -d: -f3-|tr : ' '`; do
        [ -n "$IP" ] && IP=$IP.
        let c=0x$i
        IP=${IP}$c
done

GATEWAY=`echo $IP|cut -d. -f1-3`.1

# configure the network
ifconfig eth0 $IP netmask 255.255.255.0
route add default gw $GATEWAY
------------------------------------------------------------------------

A better approach to this script is to take advantage of each distro's
network configuration system. For instance in Ubuntu/Debian you could
generate the /etc/network/interfaces file before the networking daemon
kicks in; in redhat/centos the ifcfg-eth0 file, etc...

We provide working examples for these scripts here [6].

## Generic Contextualization ##

Generic contextualization is explained in the "Contextualizing VMs
section" [5] of OpenNebula's documentation. That page provides an
example script and instructions on where to place it.

Hope this points you into the right direction, let me know if you need
extra details on any of the previous steps.

cheers,
Jaime
