ROE Kernel Hardening Continues To Restrict KVM VMs To Only Its Own Memory

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 Making Progress With Legacy-Free Display Support - Avoids Old VGA Code

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.

Tracking Mesa's VirGL OpenGL Features

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.
