Come sappiamo Canonical ha già investito molto nel progetto open source OpenStack, piattaforma di cloud computing che permette ad un amministratore di creare e gestire il proprio server cloud. Ebbene, nella versione 15.04 di Ubuntu è installata – in pre-release ed esclusiva – l’ultima versione del software. Questo aggiornamento introduce inoltre un nuovo tipo di hypervisor denominato LXD (Linux Container Daemon), in grado di lanciare e gestire sullo stesso server un cospicuo numero di macchine virtuali. Quest’ultimo è oltretutto compatibile con OpenStack.
Ancora un nulla di fatto per Unity 8 ed il nuovo server grafico Mir: a bordo di Ubuntu 15.04 troviamo il desktop Unity in versione 7.3 su server X. Nessuno stravolgimento grafico, quindi, ma una serie di bugfix e qualche nuova funzionalità aggiunta: i menu integrati localmente (LIM) possono ora essere attivati per tutte le finestre e la dash ha subito una serie di migliorie dedicate a usabilità e stabilità.
Canonical has announced the launch of Ubuntu 15.04. The new release, which will be supported for nine months, features LibreOffice 4.4, version 3.19 of the Linux kernel and a switch from Canonical's Upstart init to systemd. "systemd has replaced Upstart as the standard boot and service manager on all Ubuntu flavors except Touch. At the time of the 15.04 release there are no known major problems which prevent booting. The only service which does not currently start is Juju, which will be fixed in a post-release update soon; all other packaged Ubuntu services are expected to work. Upstart continues to control user sessions... You can boot with Upstart once by selecting `Advanced options for Ubuntu' in the GRUB boot menu and starting the `Ubuntu, with Linux ... (upstart)' entry. To switch back permanently, install the upstart-sysv package (this will remove systemd-sysv and ubuntu-standard)." The new release offers several updates and improvements for LXC containers and this is the first version of Ubuntu to offer the LXD container management utility. Ubuntu is available in a number of editions, including Desktop, Server and Snappy, a minimal "core" installation. More details on Ubuntu 15.04 can be found in the release notes.
