VirtualBox 4.1 Is Coming; Beta 1 w/ New Features

VirtualBox 4.0 was released last December and with nearly seven months passing since any major update or roadmap for a new major feature release, I had been wondering what were Oracle's future plans for this virtualization platform they received from Sun Microsystems as part of their acquisition. Fortunately, Oracle today announced the first beta of VM VirtualBox 4.1. The VirtualBox 4.1 release does deliver several new features, but nothing too ground-breaking in the heated virtualization world.

Linux 3.1 Kernel Looking To Bring New KVM Option

Back in April I reported on a lightweight QEMU-free Linux KVM host tool. This written-from-scratch solution is designed to just boot guest Linux images with the Kernel-based Virtual Machine (KVM) while being just a few thousand lines of code. A second version of the Native Linux KVM Tool has been released and it's being targeted for inclusion into the Linux 3.1 kernel.

USB 2.0 & USB-Over-Network Redirect For QEMU

While QEMU works well for many Linux users interested in virtualization and processor emulation, it lacks various features found in other virtualization solutions like Oracle VM VirtualBox and VMware's products. QEMU doesn't yet have a nice virtual graphics driver stack for accelerating 2D/3D on the host and there's limited hardware emulation. QEMU hasn't even properly supported USB 2.0 devices, but that is now changing.

VMware To Overhaul Their Virtual Graphics Driver

Two weeks ago I extensively talked about VMware's Linux graphics driver used by their virtualization products. To provide graphics hardware acceleration support within VMware guest instances, they have an elaborate (and open-source) driver stack complete with the upstream kernel DRM module and a Gallium3D user-space driver. This driver has been around since 2009, but it's about to be overhauled by VMware and it will bring some interesting changes.

OpenGL ES Support For QEMU Emulator

One of the items brought up this week at UDS Budapest was about providing OpenGL / OpenGL ES support for QEMU guests. The need for OpenGL ES 2.0 support in QEMU guests has come up since it's used in emulating Maemo / MeeGo for development environments. This would also make it possible to use Canonical's Unity desktop in a virtualized environment.

Finally It Comes: A KMS Driver For QEMU-KVM

While Linux KVM virtualization works well for many, one of the areas where the Kernel-based Virtual Machine and its QEMU integration have lagged behind other virtualization solutions like VirtualBox and VMware is in terms of its 2D/3D support within guests. The KVM-QEMU situation is slightly more positive today though with the introduction of a basic KMS (kernel mode-setting) driver for KVM-QEMU riding in the Linux kernel.

A Lightweight QEMU-Free Linux KVM Host Tool

When it comes to Linux virtualization, QEMU is one of the common parts of the virtualization stack. It's a very common emulator that provides dynamic binary translation and can run many unmodified guest operating systems on many different architectures from x86_64 to MIPS and PowerPC.

Oracle Makes TTM GPU Drivers Work On Xen

Yesterday and today there's been patches published by Oracle's Konrad Rzeszutek Wilk that make it possible for open-source GPU Linux drivers that use the TTM (Translation Table Maps) in-kernel memory management to work within Xen virtualization. The TTM drivers include the open-source Radeon and Nouveau DRM drivers, among others.

Oracle Ends The Week With VirtualBox 4 Beta 4

Oracle's been on a wild ride the past few days. Besides Oracle's second quarter earnings having beaten their own expectations and that of the street, they've been releasing updates this week to a number of their Sun-acquired open-source projects. MySQL 5.5 was finally released, Open Office 3.3 made it out (along with a new web-based Oracle Cloud Office product), and their German counterparts have been releasing VirtualBox beta releases like mad.

Oracle VM VirtualBox 4.0 Beta 3 Arrives Quickly

The German developers working on Oracle VM VirtualBox are doing well at managing to resist the temptations of Christkindlmarkts, Gl├╝hwein, and skiing, to get VM VirtualBox 4.0 out the door right away. It was just last Monday they put out the first beta followed by another before week's end. Yesterday they then put out a third beta of Oracle VM VirtualBox 4.0.

VirtualBox 4.0 Beta 2 Is Already Here

It was just on Monday that Oracle released Oracle VM VirtualBox 4.0 Beta 1 with the introduction of "extension packs", OVA format support, ICH9 and Intel HD Audio support for guests, a revamped user-interface in some areas, support for limiting a VM's CPU time and I/O bandwidth, and a number of other changes. Three days later, however, this release has been succeeded by VirtualBox 4.0 Beta 2.

VirtualBox 4.0 Beta 1 Brings Major Changes

It was more than six months ago that Oracle released Oracle VM VirtualBox 3.2, formerly known as Sun's VirtualBox, as their most recent major update. Oracle now, however, is readying a very major VM VirtualBox 4.0 update. Today they have released the first public beta of Oracle VM VirtualBox 4.0 and it brings many new features along with some changes that may prove to be another disappointing step by Oracle in alienating the open-source community.

QEMU-KVM 0.13 Is Here Too

Over the weekend we reported that QEMU 0.13 had surfaced followed by the release announcement coming out on Monday. The team working on QEMU-KVM, the version of QEMU designed for use with KVM (the Kernel-based Virtual Machine) virtualization on Linux, have also pushed out their v0.13 release based upon upstream QEMU.

QEMU 0.13 Final Is Ready With New Features

QEMU, the processor emulator that can be used alone for running unmodified guest operating systems and can optionally take advantage of KVM (the Kernel-based Virtual Machine) for greater virtualization performance with Intel and AMD hardware, has finally reached version 0.13 after suffering from a few delays. As was reported by us back in January of this year, QEMU 0.13 would focus on bringing new features and with this release they have achieved introducing several new features.

The Start Of Some KVM Virtualization Benchmarks

The last time we published any benchmarks using KVM (the Kernel-based Virtual Machine) virtualization was last year when looking at the performance with the Linux 2.6.31 kernel and before that when looking at the Intel Core i7 virtualization performance. However, a new set of Linux virtualization benchmarks are being worked on.

Virtualizing The Gallium3D Graphics Stack

Nearly two months ago we first reported on the Gallium3D driver that few knew about in the form of a Gallium3D driver that targeted the Xen virtualization platform similar to what VMware now does with its virtual Gallium3D driver for offering hardware accelerate on guest operating systems via Gallium3D. Over a number of months last year was this new Gallium3D driver, which now there is more information.

VirtualBox Continues To Gain Under Oracle

While some open-source projects formerly under the control of Sun Microsystems have been mistreated since being acquired by Oracle (i.e. OpenSolaris 2010.03 still is M.I.A. with little communication from Oracle employees), VirtualBox continues to improve. Just last week VirtualBox 3.2 Beta 1 was put out and now the second beta has arrived with more features.

The Gallium3D Driver That Few Know About

Last night it was reported on VirtualBox not being convinced about Gallium3D and what it could provide its virtualization stack not only in terms of better OpenGL acceleration for the guest virtual machines, but also for accelerating other APIs like OpenVG and OpenCL. This is coming a year after VMware rolled out its own Gallium3D driver (called "SVGA") that allowed Gallium3D to work on its virtualization platform. But there's also another virtualized Gallium3D driver out there.

VirtualBox Is Not Convinced About Gallium3D

While the VirtualBox virtualization platform that's owned by Oracle (formerly Sun) picked up OpenGL acceleration support for virtualized guest operating systems in late 2008 and then gained similar Direct3D support for VMs in early 2009, there's now an effort underway to try to get a Gallium3D driver developed.

QEMU 0.13 To Focus On New Features

This week there was the release of QEMU 0.12.2 (and the subsequent release of KVM-QEMU 0.12.2) with support for block migration, but this point release was mostly made up of small fixes and tweaks. IBM's Anthony Liguori though has begun making plans for the next major release of this open-source processor emulator. QEMU 0.13 will be the next big release and Anthony is hoping it will be completed by June and boast a large number of new features.
