Paolo Bonzini submitted the Kernel-based Virtual Machine (KVM) changes on Sunday for the now-open Linux 4.21 kernel merge window. The x86/x86_64 KVM changes represent most of the work this cycle but there are also POWER and ARM changes too.

The QEMU emulator that is widely used by the open-source Linux virtualization stack is out with its version 3.1 feature release. This is the QEMU update that is adding multi-threaded Tiny Code Generator support, display improvements, adds the Cortex-A72 model and other ARM improvements, and various other enhancements.

Red Hat developers have proposed a new VirtIO-FS component to provide better support for shared folders/files between the host and guest virtual machines.

For helping to enhance the security of servers running KVM for virtualization, there's been a ROE protection kernel hardening patch series in the works. This new addition to the kernel allows the host operating system to restrict a guest's access strictly to its own memory. It's unclear though yet if the ROE protection will make the cut in time for the upcoming Linux 4.21 kernel cycle.

QEMU 3.1.0 will be out within the next week or two depending upon any last minute blocker bugs.

Red Hat's oVirt virtualization management platform, which is used by Red Hat Enterprise Virtualization and an alternative to VMware vSphere, is working on their next feature release as version 4.3.

While VirtualBox 6.0 is in beta, VirtualBox 5.2.22 was released today as the latest stable release for this Oracle virtualization software.

The initial release candidate of the upcoming QEMU 3.1 is now available for this important piece of the open-source Linux virtualization stack.

Better/easier debugging for Intel VT-d IOMMU is on the way to help iron out any lingering issues with virtualization for directed I/O.

As part of QEMU's emulated display support they have long had a lot of old VGA/SVGA support code around. But as that code is overly complex, has been prone to security issues, and less used these days with modern interfaces, the developers behind this important piece of the open-source virtualization stack have been working on eliminating the legacy display support.

The initial round of Kernel-based Virtual Machine (KVM) updates has been sent in for the in-development Linux 4.20/5.0 kernel.

Intel developers today announced the release of KVMGT 2018-Q3 (also known as Intel GVT-g for KVM) as well as the accompany Xen hypervisor tailored XenGT 2018-Q3 update.

Intel VT-d revision 3.0 adds a "Scalable Mode" translation mode for enabling Scalable I/O virtualization and the patches have been in the works for supporting this within the Linux kernel.

The developers at Siemens AG working on the Jailhouse Linux hypervisor found it wise to issue their version 0.10 release prior to heading out to Oktoberfest.

In preparation for the upcoming VMware Fusion 11 and VMware Workstation 15 releases, their Mesa/Gallium3D-based driver stack for Linux guest GPU acceleration has been seeing a variety of updates.

The "vboxvideo" DRM/KMS driver for use by VirtualBox guest virtual machines that has been part of the mainline Linux kernel the past several cycles will soon see atomic mode-setting support.

VMware has landed more than fifty Mesa patches today adding a lot of new functionality to its "SVGA" Gallium3D driver that is used for providing OpenGL/GPU acceleration to guest virtual machines with its virtualization products.

Earlier this year MIPS rolled out the I7200 processor core built on the new "nanoMIPS" architecture. The open-source enablement of this new CPU ISA continues to settle down while the latest accomplishment is support for this new architecture in QEMU.

IBM developers on Friday posted their initial Linux kernel patches for enabling Secure Virtual Machine (SVM) support with POWER hardware.

There is a lot of new feature work for the Kernel-based Virtual Machine (KVM) within the Linux 4.19 kernel.

QEMU 3.0 is now officially available. This big version bump isn't due to some compatibility-breaking changes, but rather to simplify their versioning and begin doing major version bumps on an annual basis. As an added bonus, QEMU 3.0 comes at a time of the project marking its 15th year in existence.

For those making use of Virt-Viewer, this utility for displaying the graphical console of a virtual machine via SPICE/VNC, its version 7.0 release is now available.

The march to QEMU 3.0 is now underway following discussions at the end of last year for jumping to the v3.0 milestone after the long-running v2.x series. The first release candidate is now available and marks a hard feature freeze for the QEMU 3.0 milestone.

It's one month late but the Xen Project Hypervisor 4.11 release is available today with great scads of new features.

Intel developers working on the GVT-g graphics virtualization technology have published their latest batch of Linux kernel driver changes.

KVM maintainer for the Linux kernel, Paolo Bonzini, on Tuesday submitted the feature updates for the Kernel-based Virtual Machine in Linux 4.18.

The VirGL stack for offering OpenGL hardware acceleration to guest virtual machines with KVM is now capable of utilizing OpenGL 4.1.

It's now much easier tracking the state of VirGL that allows for OpenGL acceleration within guest virtual machines by passing on the rendering calls to the system's host OpenGL driver via Mesa and the virglrenderer library.

A new version of the Jailhouse partitioning hypervisor for Linux systems is now available.

Elie Tournier, the former GSoC student developer who was working on soft FP64 support and then joined Collabora, has shared a status update on the consulting firm's work in the GPU virtualization space.
