Suns Virtualisierungssoftware mit beschleunigter 3D-Grafik
Suns Virtualisierungssoftware VirtualBox unterstützt in der Version 2.2 das neue Open Virtualization Format (OVF) und bietet die Möglichkeit, virtuelle Appliances zu erstellen - fertig konfigurierte virtuelle Maschinen, die weitergegeben werden können.
Der von der Distributed Management Task Force (DMTF) entwickelte OVF-Standard ermöglicht es, virtuelle Appliances über verschiedene Virtualisierungslösungen hinweg einzusetzen. Der DMTF gehören unter anderem Citrix (Xen), Microsoft, Novell, Sun und VMWare an.
Darüber hinaus verfügt VirtualBox 2.2 über einen optimierten Hypervisor und unterstützt über OpenGL beschleunigte 3D-Grafik unter Linux und Solaris. Gastsysteme können zudem auf bis zu 16 GByte RAM zugreifen und ein neuer Netzwerkmodus für Host-Schnittstellen soll den Betrieb von Serveranwendungen auf virtuellen Maschinen vereinfachen.
Sun VirtualBox 2.2 steht ab sofort unter sun.com zum Download bereit. Für den privaten Gebrauch ist die Software kostenlos, für größere Installationen bietet Sun Abomodelle ab 30 US-Dollar pro Nutzer und Jahr an.

Sun unterstützt FreeBSD nicht offiziell
Die Entwickler der Virtualisierungslösung VirtualBox portieren ihre Software derzeit auf das Unix-Derivat FreeBSD. Einige Funktionen wurden bereits umgesetzt, es soll aber noch viel zu tun geben. VirtualBox-Anbieter Sun unterstützt die Portierung nicht.
Die freie Virtualisierungssoftware VirtualBox läuft bereits unter FreeBSD, haben die Entwickler bekanntgegeben. Wer die Software nutzen möchte, muss den Quelltext jedoch noch selbst aus dem Quellcodeverwaltungssystem laden und übersetzen. Den Einsatz auf Produktivsystemen empfehlen die Entwickler noch nicht.
(http://scr3.golem.de/screenshots/0905/VirtualBox_FreeBSD/thumb480/FreeBSD_win.png)
Die Virtualisierungstechnik haben sie ihren Angaben zufolge bereits portiert und auch das Qt4-Frontend ist unter FreeBSD verfügbar. Sound funktioniert über das Open Sound System und die NAT-Funktion lässt sich ebenfalls verwenden. Andere Funktionen wie Bridged- und Host-only-Netzwerk sowie Unterstützung für ACPI, OpenGL und USB hingegen sind noch nicht implementiert.
Das liegt auch daran, dass die Entwickler VirtualBox in ihrer Freizeit portieren. Anbieter Sun unterstützt FreeBSD nämlich noch nicht als Plattform. Ob sich das ändern wird, ist bisher nicht bekannt. Anwender sollen gefundene Fehler aus diesem Grunde aber nicht im offiziellen Bugtracker melden.
VirtualBox wurde ursprünglich von der deutschen Firma Innotek entwickelt, die Anfang 2008 von Sun übernommen wurde. Die Software steht unter der GPL und ist offiziell für Linux, MacOS X, Solaris und Windows verfügbar.

Probleme im SMP-Betrieb beseitigt
Sun hat die zweite Betaversion der Virtualisierungssoftware VirtualBox 3.0 veröffentlicht. Die korrigiert einige Probleme, die die erste Betaversion betrafen. VirtualBox 3.0 wird das nächste große Updates mit Funktionen wie Gast-SMP und OpenGL.
In VirtualBox 3.0 Beta 2 (http://forums.virtualbox.org/viewtopic.php?f=15&t=19126) haben die Entwickler einen Fehler korrigiert, der zu einer hohen CPU-Last durch Windows-Gäste führte. Hinzu kommen verschiedene Geschwindigkeitsoptimierungen beim SMP-Betrieb und die Unterstützung für Windows 7 wurde verbessert.
VirtualBox 3.0 wird das nächste große Update des freien Virtualisierers. Zu den neuen Funktionen zählt die Unterstützung für SMP bei Gastsystemen, so dass eine virtuelle Maschine bis zu 32 CPUs nutzen kann. Das funktioniert nur bei Computern mit VT-x oder AMD-V. In Windows-Gästen soll der Anwender Programme und Spiele nutzen können, die Direct3D 8 oder 9 verwenden. Diese Funktion ist als experimentell gekennzeichnet. Bei Windows-, Linux- und Solaris-Gästen wird außerdem OpenGL 2.0 unterstützt.
VirtualBox 3.0 Beta 2 ist ab sofort zum Download (http://download.virtualbox.org/virtualbox/3.0.0_BETA2/) für Windows, MacOS X, Linux und Solaris verfügbar.

SMP-Unterstützung für Gastsysteme
Sun hat die fertige Version der Virtualisierungslösung VirtualBox 3.0 veröffentlicht. Die bietet 3D-Funktionen für die Gastsysteme und erlaubt es, Gästen mehrere virtuelle Prozessoren zuzuweisen. Sun bietet kommerziellen Support für die Software an.
VirtualBox 3.0 unterstützt den SMP-Betrieb (Symmetric Multiprocessing) von Gästen. So lassen sich einer virtuellen Maschine bis zu 32 Prozessoren zur Verfügung stellen. Die Funktion ist allerdings nur auf Computern mit VT-x oder AMD-V verfügbar. Für Windows-, Linux- und Solaris-Gäste gibt es außerdem Unterstützung für OpenGL 2.0.
In Windows-Gästen sollen jetzt auch Anwendungen laufen, die Direct3D 8 oder 9 verwenden. Diese neue Funktion ist allerdings noch als experimentell gekennzeichnet. Voraussetzung für beide 3D-Funktionen ist eine entsprechende Grafikkarte im Host.
Weitere Änderungen und Fehlerkorrekturen sind im Changelog aufgelistet. Unter anderem gibt es eine bessere Unterstützung für USB-Geräte und APIs, um eine Webkonsole entwickeln zu können.

Oracle stellt finale Version 4.0 unter die GPL
Oracle hat die finale Version 4.0 der Virtualisierungssoftware Virtualbox veröffentlicht. Künftig werden auch die Binärdateien der Kernkomponenten der Software unter der GPLv2 veröffentlicht. Damit müssen Distributoren den Quellcode nicht mehr selbst kompilieren und paketieren. Erweiterungen für die virtuelle Maschine werden allerdings weiterhin unter der PUEL-Lizenz veröffentlicht, darunter der RDP-Server und die Unterstützung für USB 2.0.
(http://scr3.golem.de/screenshots/1005/vbox/thumb480/02_virtualbox.png)
Das Layout der Benutzeroberfläche ist umgestaltet worden: Erstmals wird in den Optionen auch ein Vorschaubild für das Gastsystem angezeigt. Zudem kann der Vollbildmodus laufender Gastsysteme durch das Herunterskalieren auf ein kleineres Fensterformat reduziert werden. Über die Gasterweiterungen können Daten vom Wirtssystem aus direkt auf die Festplatten der Gastsysteme kopiert werden.
Auf 32-Bit-Systemen kann Virtualbox 4 mehr als 2 GByte Arbeitsspeicher ansprechen. Zu den Disk-Image-Formaten, die von Virtualbox unterstützt werden, gehören das VMDK-, VHD- und das Parallels-Format. Die Virtualisierungssoftware kann auch iSCSI-Geräte ansprechen. Die Zugriffe auf die Speichermedien wurden durch die Implementierung von asynchronem I/O beschleunigt. Festplattenimages im eigenen VDI- und VHD-Format kann Virtualbox verkleinern.
Installationspakete für etliche Linux-Distributionen, sowie Windows in der 32- und 64-Bit-Version, Mac OS X und Solaris 10 5/08, sowie der Quellcode stehen auf den Webseiten des Unternehmens zum Download (http://www.oracle.com/technetwork/server-storage/virtualbox/downloads/index.htm) bereit. Oracle bietet zusätzlich eine Dokumentation (http://www.oracle.com/technetwork/server-storage/virtualbox/documentation/index.html) online und in Form einer PDF-Datei an.
