While the VirtualBox DRM/KMS driver was merged for Linux 4.13 as one step towards improving the out-of-the-box support for Linux guests on Oracle VM VirtualBox, other drivers remain out-of-tree still, but that is slowly changing.

The Oracle developers behind VM VirtualBox have released a new maintenance build in the VirtualBox 5.2 series that is a bit more exciting than their usual point releases.

There are a ton of exciting improvements building up in Linux 4.15, but not too much on the virtualization front.

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.
