Virtualbox KVM Backend Introduces SR-IOV Graphics Support

According to Phoronix, the newly introduced KVM back-end for VirtualBox, initially revealed by Cyberus Technology one month ago, has been updated to include support for SR-IOV graphics virtualization. This development is particularly noteworthy for users who are familiar with the VirtualBox VMM interface and workflow but are interested in utilizing the Kernel-based Virtual Machine (KVM) for its underlying virtualization capabilities.

The addition of SR-IOV graphics virtualization to the VirtualBox KVM back-end allows for near-native graphics performance, with Cyberus Technology reporting about 92% of the host’s native graphics performance. This enhancement has been tested with both Windows and Linux guests, though there are some noted limitations. These include the lack of support for guest multi-monitor setups, save state and resume functions, and various limitations specific to Windows guests.

For those interested in more detailed information about this graphics virtualization support, further details can be found on the Cyberus blog. This update represents a significant step forward for users seeking to leverage the power of KVM hypervisor technology in conjunction with the familiar VirtualBox interface.
