Esta nueva versión del código abierto Xen 3.3 incluye características importantes, como por ejemplo:
* 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
Otros hypervisors basados en Xen como por ejemplo Citrix XenServer, Virtual Iron, Oracle VM y en algún grado Sun xVM Server, así como algunos sistemas operativos Enterprise como Novell SUSE Enterprise Linux y Red Hat Enterprise Linux, empezaran a integrarse con las nuevas características en los próximos meses.
