Citrix has released Service Pack 2 for XenServer 5.6.

Here is what’s new Features Since XenServer 5.6 Feature Pack 1

XenServer 5.6 Feature Pack 2 includes number of new features and ongoing improvements, including:

• IntelliCache. Using XenServer with IntelliCache makes hosted Virtual Desktop Infrastructure deployments more cost-effective by enabling you to use a combination of shared storage and local storage. The load on the storage array is reduced and performance is enhanced. See the XenServer Service Pack 2 Installation Guide for more information on this feature.
• WorkLoad Balancing Installation Improvements. Choice of English or Japanese language available on installation screens.
• Local Storage Spans All Physical Volumnes. When EXT local storage is used (e.g. when the “Use thin provisioning” is selected in the host installer), on a host containing multiple physical disks, the local Storage Repository (SR) now spans all the disks in a single LVM volume group.
• Reset-on-boot VM behaviour. Disks with the “on-boot” option set to “on reset”, is now available for disks in any type of SR. (Previously it was only available for disks in NFS and EXT SRs.)
• Block SCSI Generic Support. BSG support added enabling full compatibility with Emulex and QLogic management functionatility.
• Enhanced guest OS support. Support for Red Hat Enterprise Linux (RHEL) 6.

It also includes some minor hotfixes since XenServer 5.6 Feature Pack 1.
