QEMU 1.5: GPU pass-through and ARM support
The recently released QEMU 1.5 supports virtualisation with KVM on the Cortex A15 series of ARM cores. Another new addition is an experimental feature for passing through graphics chips from the host to the guest via VFIO; however, the feature is currently only thought to work reliably with some of the graphics chips. Both features rely on Linux kernel support that became available with Linux 3.9.
