Abstract
IBM i Virtualization Summary
Content
The summary on this page indicates the minimum IBM i operating system levels that are supported for the IBM i virtualization functions. There is also a column that indicates the type of environment:
- VIOS (for functions that require a VIOS configuration)
- iVirtualization (for functions that are supported in a configuration where IBM i is serving I/O to a client IBM i, AIX, or Linux partition, or where IBM i is a client of an IBM i partition)
- Native (for functions that are supported for Native SR-IOV configurations).
For IBM i Virtualization configurations:
- The hosting partition can be any IBM i release, IBM i 6.1 or newer, that is supported on a particular Power System processor generation natively.
- The client partition can be any IBM i release, IBM i 6.1 or newer, that is supported on that same Power System processor generation natively or with VIOS.
- For example, IBM i 7.1, on a Power System with POWER6 technology, can have client partitions that are IBM i 6.1 or 7.2; however, IBM i 7.3 is not supported on POWER6, so it cannot be a client of IBM i 7.1 on a POWER6 system.
For more information about iVirtualization, see IBM i Virtualization and Open Storage.
