The IBM Software Product Compatibility Reports (SPCR) pages are a complete source of
hardware requirements, supported operating systems, prerequisites and optional supported software,
with component-level details and operating system restrictions. This topic provides direct links to
reports for Db2® 11.5
Hardware embedded full virtualization and Db2 11.5
supports hypervisors fully embedded in hardware and firmware when operating system requirements are
met. Some examples are systems equipped with Power Hypervisor, VMware ESX 3i, or Hitachi Virtage.
Note: Any enhancements in hypervisor function that come in the form of separate software are not
included in the definition of "Hardware Embedded".

technology. Hypervisors in use must run a supported enterprise OS (For example, KVM with RHEL
Enterprise support. KVM running CentOS is not recommended).
OS virtualization that supports Db2
11.5 is available
to enterprise-ready and licensed hypervisors that have the write-thru feature enabled.

If IBM believes that an issue is specific to a virtualization technology (such
as performance or communication with peripheral and hardware components), IBM might require that the
customer reproduce the issue in a non-virtualized configuration. Due to the nature of virtualization
technologies, IBM cannot guarantee levels of performance that are impacted by a customer’s
virtualized deployment. Similarly, IBM cannot guarantee resolutions to issues that are caused by a
customer’s virtualized deployment.
