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.
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.
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.
For the many Linux virtualization users out there using Red Hat's virtualization stack with libvirt, virt-manager, virt-viewer, etc, version 0.9.0 of their virtualization platform management library (libvirt) is now available.
For those of you that prefer Xen virtualization under Linux rather than KVM/QEMU, VirtualBox, VMware, or any of the other virtualization solutions available, the Xen 4.1 Hypervisor has just been released with some major changes.
While it was not long ago that QEMU 0.13 was released, QEMU version 0.14 is now available with more improvements to this open-source processor emulator.
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's VM VirtualBox virtualization software just went into beta two weeks ago, but since then they have put out four beta releases. Now though Oracle is already ready to announce the official release of VM VirtualBox 4.0.
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.
The German developers working on Oracle VM VirtualBox are doing well at managing to resist the temptations of Christkindlmarkts, Glühwein, 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.
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.
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.
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, 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.
It's been two months since the last VirtualBox 3.2.x point release arrived (VirtualBox 3.2.8) and five months have passed since VirtualBox 3.2 was introduced. There's no signs yet of version 3.3 for Oracle's VirtualBox with no stable or development releases being on the horizon, however, today VirtualBox 3.2.10 has been pushed out.
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.
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.
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.
While Oracle has yet to put out OpenSolaris 2010.03 and they have disbanded other open-source projects formerly under Sun's umbrella, they are moving full-steam ahead with Virtualbox. This morning Oracle has put out the VirtualBox 3.2 Beta, which re-brands itself as Oracle VM VirtualBox.
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.
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.
Xen 4.0 was just released a few days back with a variety of features from graphics card pass-through support to online resizing of guest disks, but features for Xen 4.1 are already brewing. Xen 4.1 will be the next major release for this once-popular virtualization platform and its feature list is quickly growing.
While the Xen virtualization platform has lost much of its spotlight to KVM, the Kernel-based Virtual Machine that has been living in the mainline Linux kernel for a few years now, Xen 4.0.0 has made it into the world this week.
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.
Version 0.12.2 of qemu-kvm was released earlier this week. This version continues to be derived from the upstream QEMU code-base with various KVM enhancements. For the most part it's various fixes making up the qemu-kvm 0.12.2 release, but there is a new feature and that is block migration.
Virt-Manager, the GUI-driven virtualization manager that was started by Red Hat about three years ago is out this week with a new update. From the version number, 0.8.1, it may seem like a small update as the previous release was v0.8.0 and it already brought an improved GUI and other advancements, but in fact the new point release is quite significant.
Recently we have been talking a lot about VMware's Gallium3D driver that they recently released along with DRM code that does support kernel mode-setting and allows this new 3D driver to function under their virtualization platform. By running this Gallium3D driver on the guest operating system of their VMware virtualization platform, it's possible to leverage the GPU hardware acceleration on the host not only for OpenGL acceleration but for areas of other state tracker coverage like OpenCL, OpenVG, X-Video / X11, and more. This virtual Gallium3D driver really makes things interesting in the virtualization world for the GPU.
Earlier this month we talked about new VirtualBox 3.1 features when this Sun virtualization platform was still in beta, but this morning VirtualBox 3.1 final is now out the door for those interested in Windows, Linux, and Solaris virtualization. VirtualBox 3.1 adds support for teleportation (live migration of VMs between hosts), VM states can now be restored from arbitrary snapshots, network attachments can now be changed on active VMs, and support for more flexible storage attachments.
For months Sun's VirtualBox virtualization software picked up OpenGL and Direct3D acceleration support for virtualized guest operating systems, but now 2D/3D hardware-acceleration support for those running operating systems under VMware's virtualization products are imminent.
Sun Microsystems had released VirtualBox 3.0 earlier this year with OpenGL 2.0 support for guests, long-awaited SMP guest support, and other improvements. This was a nice release for this virtualization platform, but VirtualBox 3.1 is now approaching. The first beta release of VirtualBox 3.1 has been released today and it brings a few key changes.
