DEMO Creating an image Uploading to OpenNebula Creating a template Sharing with others

Creating new images New images can be created in many ways Booting a blank disk image with a bootable CD (image) and install the OS Using kickstart or debootstrap (I guess) the easiest (and most beautiful) way with ubuntu: $ sudo vmbuilder kvm ubuntu --suite precise --flavour virtual --arch amd64 -o --libvirt qemu:///system -- hostname myvm --user user --pass summerschool -- addpkg acpid --addpkg openssh-server --rootsize swapsize=64

Uploading to OpenNebula

Creating a template

Sharing with others Images and templates can be shared as well However sharing needs administrator role at this moment 

Exercise II. Start a VM with the shared template Connect it via VNC and SSH Install the lighttpd package Create a copy from the non- persistent image Make the new image persistent Try it!

Hints (1) SSH is more comfortable than VNC for server VMs (e.g: ssh Installing lighttpd package $ sudo bash #password is ”summerschool” $ apt-get –y install lighttpd $ echo ”Hello Cloud, username” > /var/www/index.html Check it with your browser! Use ”Save as” (and ”Shutdown”) to clone running VMs

Hints (2) Just one instance can be started from a persistent image! If you still have time  Create an instance from ”SummerSchool2012-Portal” and practice the portal installation procedure.
