  • PVGrub: boot PV kernels using real GRUB inside the PV domain
  • Better PV performance: domain lock removed from pagetable-update paths

  • PVSCSI drivers for SCSI access direct into PV guests
  • HVM framebuffer optimisations: scan for framebuffer updates more efficiently
  • Device passthrough enhancements
