The KVM (Kernel-based Virtual Machine) and Xen updates have been submitted for the Linux 4.14 kernel merge window.

LXC 2.1 is now available as the latest version of Linux Containers for OS-level virtualization in allowing multiple Linux containers to run simultaneously off the mainline Linux kernel.

QEMU 2.10 is now available as the latest release for this important piece of the open-source Linux virtualization stack.

While there has been VirGL as one of the options for allowing 3D/OpenGL acceleration of Linux guests within QEMU/KVM virtual machines to allow the calls to be directed to the host system's OpenGL driver, that support hasn't been available when Windows is running as QEMU/KVM guest. That is changing though thanks in large part to this year's Google Summer of Code.

For those making use of Red Hat's oVirt as a virtualization management platform, there should be better performance now when using the Gluster network-attached file-system.

QEMU 2.10 is under development as the next step for this important piece of the open-source Linux virtualization stack.

The Xen feature updates have been submitted for the Linux 4.13 kernel merge window.

The Kernel-based Virtual Machine (KVM) has seen a wide assortment of updates for the Linux 4.13 kernel merge window.

With the Linux 4.12 kernel when running in emulated environments like VMs/clouds atop NVMe (NVM Express) solid-state storage you should be able to obtain much greater performance.

The "vboxvideo" kernel driver providing DRM/KMS display support for VirtualBox guest virtual machines has been going through a rework with plans to mainline this driver in the Linux kernel.

The latest feature-work for Xen is on a back-end for the new PV Calls protocol.

Upstream QEMU developers are looking at dropping support for sub-optimally supported hosts/platforms if there are not maintainers willing to take over the responsibilities. As such, there's now a NetBSD volunteer looking to improve their OS support on QEMU with this being an important piece of the open-source virtualization stack.

The Kernel-based Virtual Machine changes have been submitted for the Linux 4.12 kernel merge window.

The Xen virtualization changes have been submitted for the Linux 4.12 merge window.

Bareflank 1.1 is now available as the newest release of this open-source lightweight hypervisor written in C++.

Version 0.7 of the Jailhouse Linux hypervisor has been released.

The QEMU project is hoping for some interested developers to enhance VirGL for better offering OpenGL guest support with QEMU guests and possibly extend it to include Vulkan support.

QEMU 2.9-rc0 was tagged yesterday as this important piece of the open-source Linux virtualization stack prepares for its next major release.

The Kernel-based Virtual Machine (KVM) changes have arrived for the Linux 4.11 kernel and there is a lot of them with over 200 commits and the introduction of new features for many of the supported architectures.

The oVirt project has announced their major v4.1 release with a lot of new functionality. The oVirt project is an alternative to VMWare's vSphere for open-source virtualization management.

The libvirt virtualization API saw a major 3.0 release this week to succeed its earlier v2.5 milestone.

With the Linux 4.10 kernel there is initial mainline support for Intel GVT-G (Graphics Virtualization Technology) while it will become more usable in future updates.

Radeon developers have issued updated patches for their AMD GPU virtualization support.

The ARMv8.3 specification is adding support for nested virtualization and already kernel developers have been working to take use of this feature on future ARM CPUs within the Linux kernel.

A new release is now available of the Jailhouse 0.6 partitioning hypervisor that remains an out-of-tree option for Linux server admins.

Being announced today on the kernel mailing list is the KSM hypervisor, what's self-described as "a hackable x86-64 hypervisor."

QEMU 2.8 is now available as a significant update to this important piece of the Linux virtualization stack.

RISCVEMU is a RISC-V system emulator designed by the talented developer Fabrice Bellard. This RISC-V emulator supports RISC-V to the extent it can boot the Fedora spin for this architecture.

Earlier in the week the KVM and Xen updates were sent in for the Linux 4.10 kernel to add to the list of changes so far for Linux 4.10.

Back during the summer we wrote about the Bareflank Hypervisor as a new open-source hypervisor written in C++11/14 and served as more of a hypervisor framework. Today the company behind that effort, Assured Information Security, announced a new version of Bareflank.
