This article has been created by an automatic translation software. You can view the article source here.
The following procedure explains how to create a model compatible with Cloud Ikoula from an installation from scratch (from a iso ).
In our example, we will create a GNU image /Linux Fedora 22.
Log on to the interface Cloud Ikoula :
Click on "Models " in the left menu :
Select the view "ISO" :
Click on the button "Save ISO " :
Then fill in the fields :
1: Enter the name you want for your image
2: Enter a description for your image
3: Enter /Paste the HTTP u (non-http) full iso file
4: Select the Cloud Ikoula area for which your image will be available
5: Select this checkbox if you want an instance to be able to boot from your iso
6: Indicate the type of system your ISO, if your system and the version of it is in the list select the otherwise choose one type "Other xxx" the most suitable. In our case, Fedora 22 was not available in the list we have therefore selected "Other Linux (64-bit)".
7: Check this case if you want that your ISO can be downloaded once created
Once your ISO registered, wait until it is in status "Loan : Yes" :
Click on "Instances" in the left menu :
Click on the button "Add an instance " :
Select your instance deployment area :
Select ISO and click on "Follow"
Click on the tab "My ISOs" and select the iso you just create :
Select the offer for the calculation of your choice and then c "Follow"
Made slide the cursor to select the size of disk (GB ) that you want for your instance and therefore for your future model or enter the size (GB ) manually in the field and then confirm with the button "Entry " your keyboard to make the selected appears in the description at the top :
Click on "Follow"
Continue the classic stages of deploying an instance (Affinity, nawork, instance name ) clicking on "Follow" at each time to validate and then click "Start VM "
Once your instance has been deployed, click the name of the (from the Instances me) :
Click on the button "See the consol" (Note that you see your ISO image attached to your instance into the details of this ) :
A new pop-up browser window will open (If this is not the case check that you not block it the pop up for the Cloud Ikoula interface ). This window is actually a web GUI console type VNC /KVM (écran/clavier/souris) your instance which will allow you to install the system on the disk of your instance :
Continue with the installation of your system with the partitioning and configuration you want (install the SSH package if prompted ), note, however, that the keyboard is not of type QWERTY (attention therefore to the definition of passwo).
At the end of the installation when it is asked to you click on restart, stop your instance to detach ISO
Once your instance is stopped, click the name of your instance and then the button "Detach the ISO image" :
Once the iso detached from your instance, you can again start it to start on the system that you just installed on the disk (ROOTDISK) of the latter.
Click on the button "See the consol" to see your booted system :
Connect with SSH to your instance (You must have create a firewall rule and redirection of port if your instance is in zone /network advance or an inbound rule of security group if it is in zone basic and does not have rules iptables on your instance system ) to complete the configuration of the system to make it compatible with Cloud Ikoula.
With regard to a virtual context, we relied on a partitioning with LVM (root and swap logical volumes ) in order to easily resize our partitions in case of resizing or adding a virtual disk :

Update the system if necessary (to adapt to your package manager ) :
[root@Fedora22x64 ~]# dnf upgrade
Please install the minimum packages which can be used to execute commands in settings "UserDat" during a deployment for instance w your templat : Vim, rsync, curl, wget, cloud-init, puppet, facte :
[root@Fedora22x64 system]# dnf list installed vim-enhanced rsync curl wget cloud-init puppet facter

[root@fedora22 ~]# head -n1 /etc/cloud/cloud.cfg

You should now reboot this Virtual Machine.
Restart your instance as this prompted :

You can delete the installation files :
[root@Fedora22x64 ~]# rm -rf linux65*
[root@Fedora22x64 ~]#
We add the following lines in /etc/sysctl.conf (It disables API 6 and applied some optimizations ):
#Disable IPv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.eth0.disable_ipv6 = 1
#Disable Swap
vm.swappiness = 0
#Improve memory management
vm.dirty_ratio = 60
vm.dirty_background_ratio = 2
#No overcommitment of available memory
vm.overcommit_ratio = 0
vm.overcommit_memory = 0
#Set maximum amount of memory allocated to shm to 256MB
kernel.shmmax = 268435456
kernel.shmall = 268435456
#Keep at least 64MB of free RAM space available
vm.min_free_kbytes = 65535
Then we execute the command "sysctl -p" :
[root@Fedora22x64 init.d]# sysctl -p
net.ipv4.conf.all.arp_notify = 1
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.eth0.disable_ipv6 = 1
vm.swappiness = 0
vm.dirty_ratio = 60
vm.dirty_background_ratio = 2
vm.overcommit_ratio = 0
vm.overcommit_memory = 0
kernel.shmmax = 268435456
kernel.shmall = 268435456
vm.min_free_kbytes = 65535
It modifies the SELinux policy to pass it from "enforcing" à "permissive" :
[root@Fedora22x64 ~]# sed -i 's/SELINUX=enforcing/SELINUX=permissive/g' /etc/sysconfig/selinux
[root@Fedora22x64 ~]# setenforce Permissive
[root@Fedora22x64 ~]# sestatus
SELinux status: enabled
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: permissive
Mode from config file: enforcing
Policy MLS status: enabled
Policy deny_unknown status: allowed
Max kernel policy version: 29
If your system has rules of origin firewall, please stoppper and disable it, in our case example :
[root@Fedora22x64 ~]# systemctl stop firewalld.service
[root@Fedora22x64 ~]# systemctl disable firewalld.service
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.
It verifies that it has more rules of responsible :
[root@Fedora22x64 ~]# iptables -vnL
Chain INPUT (policy ACCEPT 34 packets, 2240 bytes)
pkts bytes target prot opt in out source destination
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
Chain OUTPUT (policy ACCEPT 32 packets, 3568 bytes)
pkts bytes target prot opt in out source destination
We now install the Cloud guests scripts on which are based the functionality of change of password, hostname, userdata's SSH keys :
- First, retrieve the archive containing the scripts on our mirror (Edit fedora 22 by centos7, debian8 or ubunt1404 in the following u) :

- We purge the DHCP leases file (path and name of file to suit the need ) :
[root@fedora22 ~]# > /var/lib/dhclient/dhclient.leases
- On purge master logs files and command history :
[root@Fedora22x64 ~]# list=`find /var/log/ -type f`
[root@Fedora22x64 ~]# for arg in $list ; do > $arg ; done
[root@Fedora22x64 ~]# list=`find /var/log/ -name "*.gz"`

[root@Fedora22x64 ~]# > .bash_history
[root@Fedora22x64 ~]# history -c && shutdown -h now && exit
- It created the model of our quit instance :
On the Cloud Ikoula interface, go in "Instances" then click on the name of your instance
Click on "See Volumes" :
Click on the name of your volume ROOTDISK :
Click on the button "Create a templat" :
Give the name and the description that you want to your model, choose the same type of bone than that of your instance, check "Password enabled " et "dynamic resizing " (If you have respectively set up the cloud-set-guest-password script and installed the xentools ) :
Once finished creating your template :
You can find it in "Models " :
The name of your template and click the tab "Area" to verify that its status is ready (Loan : Yes) :
You can now deploy new instances with your compatible model Cloud Ikoula (you will need to select your model in the tab "My template" the instance deployment wizard) :
