Novell announces SLES 11 Service Pack 1, introduces Xen 4.0, KVM support and Linux Integration Services for Hyper-V

Yesterday Novell announced the Service Pack 1 for its SUSE Linux Enterprise Server (SLES) 11.

The package seems strictly focused on virtualization, as it includes the new Xen 4.0 and introduces for the first time support for KVM.

More than that, SLES 11 SP1 ships with Linux Integration Services (LIS) for Microsoft Hyper-V, something that no other distribution offers today.
The most wanted version of LIS is the 2.1 which introduces support for 4 vCPUs per virtual machine, and despite it still is in Release Candidate status Novell may be in time to include it as this Service Pack 1 is scheduled for a June 2 release.

The Service Pack 1 is also introducing another important capability for virtual infrastructures: the support for the new Intel Xeon 5600 and 7500 CPUs, which greatly improve hypervisor performance.
