Summary :
This SAP Note outlines the configurations and prerequisites for running SAP in a virtualized environment using KVM on Linux, specifically with Red Hat Enterprise Virtualization (RHEV) and Red Hat Enterprise Linux (RHEL). Key points include the support of SAP on RHEL versions 5.4 and newer, and RHEV 3.0 to 3.1, excluding RHEV 2.x due to insufficient monitoring capabilities. The configuration requires an active subscription to "Red Hat Enterprise Linux for SAP Business Applications" for each RHEL guest running SAP software. Important setup guidelines include enabling CPU hardware virtualization features in BIOS, utilizing VM configurations appropriate for SAP workloads, and installation of necessary monitoring packages ('vhostmd' and 'vm-dump-metrics') for effective metrics monitoring in SAP environments. Additionally, storage best practices entail using raw partitions or LVM devices for KVM hosts and configuring network settings optimally for performance.
