There's a lot of virtualization improvements coming to Xen 4.3 that will be released in the months ahead while when it comes to the Xen work directly within the Linux kernel, there's good stuff happening for Linux 3.9.
Xen 4.3 is expected to be released in June of this year. While the developers working on this virtualization platform are only half-way through its development cycle, they already have an impressive number of features that are coming into this next open-source release.
Red Hat may finally get to developing a KMS/DRM driver for QXL/SPICE to be used in conjunction with QXL for virtualization. This is a stepping-stone to eventually supporting SPICE 3D for allowing Red Hat virtual machines to tap hardware graphics acceleration support.
One of the major limitations of QEMU/KVM when it comes to Linux desktop virtualization is that it hasn't provided any form of support for graphics acceleration -- either by passing OpenGL calls onto the host for execution by the host's driver and graphics hardware or allowing guest VMs to tap directly the graphics card. Support for the latter feature continues to be developed and is close to becoming a working reality.
Xen Orchestra is an open-source project that gives a web-interface to the Xen virtualization platform via XCP and its API (XAPI).
VMware is still trying to push VMCI (the Virtual Machine Communication Interface) and VSOCK (VMCI Sockets) into the mainline Linux kernel. Fortunately, it looks like this virtualization code from the proprietary software vendor will make it into the Linux 3.9 kernel.
It's been two months since the last update to Oracle's cross-platform VirtualBox software but yesterday evening a new point release was made available that has a plethora of fixes and other minor improvements.
Here's a report on the state of KVM Nested Virtualization for Linux in dealing with multiple layers of virtualization.
QEMU 1.3.0 was released on Monday afternoon and supports a large number of new features for this open-source package that's common to the Linux virtualization stack.
Released on Monday was the "RC0" development version of QEMU 1.3 for the open-source processor emulator commonly used with the Linux KVM virtualization stack.
While there's usually always something to talk about with each new kernel release for the Intel, Radeon, and Nouveau DRM/KMS drivers, that isn't always the case for VMware's "vmwgfx" virtual GPU driver. This driver for exposing 3D acceleration to guest virtual machines on VMware's virtualization products does work quite well already, but the open-source developers have been recently working on a few improvements.
Within the forthcoming Linux 3.7 kernel there is support for Xen virtualization support on ARM when using a Cortex-A15 SoC. While not yet merged to mainline, KVM virtualization support for the ARM architecture is also coming about.
VMware developers continue to work on mainlining more of their Linux kernel code to support their virtualization platform in the name of improving the "out of the box" experience for Linux VM guests. The latest work has been on pushing forward VMCI and VSOCK for the mainline Linux kernel.
Xen virtualization support for the ARM architecture is now set to be pulled for the Linux 3.7 kernel.
The OpenStack Infrastructure-as-a-Service cloud computing platform has now released version 2012.2 Folsom.
Many Phoronix readers have been asking about VMware Fusion 5.0 benchmarks, so here are some numbers for those wondering about this closed-source virtualization product for running other operating systems atop Mac OS X.
After several test releases, VirtualBox 4.2 was officially released this morning.
QEMU, the popular open-source emulator/virtualizer commonly used in conjunction with KVM, had a fairly quick v1.2 development cycle but that doesn't mean it's weak on changes.
A third release candidate of VirtualBox 4.2 was released this week.
Less than two weeks after VirtualBox 4.2 Beta 1, Oracle's German office has released the first release candidate of VirtualBox 4.2.
Xen 4.2 will be released in the near future for this one of the leading virtualization platforms available for Linux. Xen 4.2 is packing in a number of new features.
Dell has written a guest post on Phoronix with some Linux virtualization tips.
VMware is preparing to push VMCI support into the mainline Linux kernel.
QEMU 1.1 provides experimental support for USB 3.0 devices, which provides higher transfer through-put rates while sometimes at a lower CPU usage rate.
With the ongoing work to better enable virtualization support for the ARM architecture under Linux, the developers working on Xen enablement have reached a new milestone.
For those not up to speed on the latest features for Linux virtualization when using QEMU/KVM, there is support since for USB device redirection over the network for virtual machines.
To further enhance the Linux virtualization experience with VMware products, the company is preparing to push the Virtual Machine Communication Interface and VMCI Sockets into the mainline Linux kernel.
For those wanting to setup a Xen VGA pass-through configuration whereby your host graphics card can be controlled by a guest operating system, like Windows within Linux, here's a guide how to setup this interesting feature.
The xf86-video-vmware 12.0 driver was officially released yesterday, which now means all of the components needed for 3D Linux guest acceleration are now available and stable.
After thoroughly testing the VMware graphics driver stack yesterday and providing benchmarks, there's some new "vmwgfx" developments to report on.
