    Abstract

    This IBM Redbooks publication discusses running Linux under z/VM on IBM System z9 and zSeries platforms. We describe enhancements available in z/VM Version 5.1. The intended audience for this book is IT administrators responsible for installing and configuring z/VM 5.1 systems running Linux guests.

    Using Fibre Channel Protocol (FCP), z/VM 5/1 can be installed on and operate from SCSI disks. Configured as emulated Fixed Block Architecture (FBA) disks, z/VM 5.1 can use FCP-attached disks for its system paging, spooling, directory, and minidisks.

    z/VM 5.1 adds new functions for Virtual Switches (VSWITCH). For increased network security, guests must have authorization before connecting to a VSWITCH. z/VM 5.1 introduces VSWITCH Layer 2 support. Operating at Layer 2, a VSWITCH delivers and receives network traffic in Ethernet frames. This provides the ability to handle non-IP protocols such as SNA, NetBIOS, and IPX. In addition, Layer 2 support reduces network latency and CPU overhead.
