Xen 3.0.4

Welcome to the Xen 3.0.4 download page! This is largely an opportunistic stabilising release for HVM guests, due to the large amount of work in that area of the code since 3.0.3. These enhancements have in particular improved support for SMP and ACPI Linux and Windows operating systems.

Other highlights of this release include:

  • support for kexec/kdump of Xen and domain 0;
  • graphical framebuffer support for paravirtualised guests;
  • preview support for the new XenAPI management interfaces;
  • enhanced support for IA64 (IPF) and Power systems.
  • Xen 3.0 Datasheet

The downloads on this page have been built from the latest Xen 3.0.4 official release. They have undergone limited testing,
are not supported in any way whatsoever, and will be fixed on a best-effort basis only. Downloading or installing any
package from this page constitutes an acknowledgement and acceptance of the warranty disclaimer and copyright information.
Downloads for the previous 3.0.3 and 3.0.2 releases are also available.

The following hardware configurations have been tested with Xen 3.0 using the Xen 3.0 Test CD. Please run the test CD
on your hardware to help us grow the list and identify platforms that need attention.

Xen 3.3.0

Welcome to the Xen 3.3.0 download page! This release contains architectural improvements and new user-visible 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
  • RAS features: cpu and memory offlining
  • Power management: improved frequency/voltage controls and deep-sleep
  • support. Scheduler and timers optimised for peak power savings.
  • Support for the Viridian (Hyper-V) enlightenment interface
  • Many other changes in both x86 and IA64 ports
  • Xen 3.3 Datasheet
