Comprehensive Virtualization Support OverviewIncluded with SUSE® Linux Enterprise Server 11 Service Pack 3 (SP3) are the latest open source virtualization technologies, Xen and KVM. With these hypervisors, SUSE Linux Enterprise Server can be used to provision, de-provision, install, monitor and manage multiple virtual machines (VMs) on a single physical system.

1 SUSE strongly recommends using paravirtualized device drivers for fully virtualized machines. These drivers enhance network and storage I/O performance. For SUSE Linux Enterprise Server, they are included directly in the operating system. For Windows, they are available in the SUSE Linux Enterprise Server Virtual Machine Driver Pack. For additional information on paravirtualized device drivers for Windows please visit: www.suse.com/products/vmdriverpack

2 Processors are hotpluggable into the available sockets of the system’s motherboard. Intel and AMD processors can feature one, two or more CPU cores. CPU cores can provide logical CPUs if supported by the CPU design. Logical CPUs are often referred to as logical hardware threads (LHT). In some circumstance SUSE recommends disabling hyperthreading (in old style dual core hyperthreaded processors) to improve the VM performance.

SUSE LINUX ENTERPRISE SERVER 11 SP3 FEATURE SUPPORT—
Note:.The addition or removal of physical CPUs at runtime is not supported; however, virtual CPUs can be added or removed for each VM. CPU pinning allows logical CPU to virtual CPU assignment for a specific VM.
SUSE LINUX ENTERPRISE SERVER 11 SP3 FEATURE SUPPORT—
PARAVIRTUALIZED GUEST
Note:.Virtual CPU capping allows you to set vCPU capacity to 1–100 percent of the physical CPU capacity.
