Folks,
We''re pleased to announce the official release of Xen 3.3.0!
This is a major new release with a host of new features including:
- Power management (P & C states) in the hypervisor
- HVM emulation domains (''qemu-on-minios'') for better
scalability,
performance and security
- PVGrub: boot PV kernels using real GRUB inside the PV domain
- Better PV performance: domain lock removed from pagetable-update paths
- Shadow3: optimisations to make this the best shadow pagetable algorithm
yet, making HVM performance better than ever
- Hardware Assisted Paging enhancements: 2MB page support for better TLB
locality
- CPUID feature levelling: allows safe domain migration across systems with
different CPU models.
- PVSCSI drivers for SCSI access direct into PV guests
- HVM framebuffer optimisations: scan for framebuffer updates more
efficiently
- Device passthrough enhancements
- Full x86 real-mode emulation for HVM guests on Intel VT: supports a much
wider range of legacy guest OSes
- New qemu merge with upstream development
- Many other changes in both x86 and IA64 ports
