Overview

New Feature Highlights

TBD

A more complete list of features can be found on the Xen 4.4 Feature List

Build Requirements

The default installation prefix has been changed to /usr/local. Previously the default installation prefix was /usr To restore the previous behaviour, specify --prefix=/usr when running ./configure, e.g.: 

$ ./configure --prefix=/usr

If you choose to accept the new default then be sure to cleanup any residual bits of the old installation in the old prefix, especially libraries and tools which you might pick up by mistake.

Due to this change it may also now be necessary to run /sbin/ldconfig as root after installing Xen.

Note also that Xen now requires gcc v4.1 or greater.

Other changes

  • Support for x86 32-bit and ia64 (itanium) hypervisors has been removed. 32bit VMs, including 32bit dom0, are still supported on the x86_64 64bit hypervisor.

Known issues

  • The Xen Security Module (XSM) will not compile on the ARM architecture.
