- An optional account for anonymous logons.
- An operating system that runs in a virtual machine managed by the z/VM Control Program (CP ).
A secondary partition that runs an operating system other than i5/OS. The guest partition requires another partition to host it. The purpose of the hosting partition is to supply paths from virtual I/O in the guest partition's operating system to real I/O hardware drivers in the hosting partition.
guest platform management provider (GPMP)
An optional suite of applications that is installed in specific z/OS, Linux, and AIX operating system images to support platform management functions. For example, the guest platform management provider collects and aggregates performance data for virtual servers and workloads.
guest virtual machine (GVM)
In z/VM, the functional equivalent of a System z9 or zSeries system, including the virtual processors, virtual storage, virtual devices, and virtual channel subsystem allocated to a single user. Each guest virtual machine can be controlled by an operating system, such as CMS, z/VSE, z/OS, or Linux.

In capacity planning, a value used as a general guide for optimal resource utilization. If resource utilization is above the guideline value, the resource may be approaching a problem area or a threshold value. Guideline values are also available for the rate of synchronous reads in the machine pool and for the sum of all pools. See also threshold value.
A community of interest that spans across a tribe. Members join the guild in order to share their knowledge of tools, code, and best practices. Guilds are similar to chapters but are not limited to people with the same responsibilities within a tribe. For example, the web technology guild could include some testers, some web developers and some UI designers within the tribe. See also chapter, squad, tribe.
