DB2 Supported Environments for Virtualization

IBM DB2 only supports the environments listed on this page. This page will be updated as new environments become validated.


Hardware Embedded Full Virtualization Environments

DB2 supports hypervisors fully embedded in hardware/firmware as long as 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". See the below categories for software virtualization technologies that are currently supported.


DB2 Supported Full Virtualization Environments for x86 and x64 Architectures


Hypervisor Architecture Minimum Guest OS (Windows) Minimum Guest OS (Linux) Minimum DB2 Level
VMware ESX 3.0.1 and higher
VMware vSphere 4 		x86/x64 System listed on ESX HCL Any Microsoft Windows level supported by both DB2 and ESX Any Linux distribution supported by both DB2 and ESX DB2 9
DB2 9.5
DB2 9.7
*Red Hat Enterprise Linux
(RHEL) 5.4 and higher
KVM 		x64 System with: INTEL-VT or AMD-V Not Supported RHEL 5.4 64bit DB2 9.7
*Red Hat Enterprise Linux
(RHEL) 5.2 and higher
Xen HVM 		x64 System with: INTEL-VT or AMD-V Not Supported RHEL 5.2 64bit DB2 9 FP4
DB2 9.5 FP1
DB2 9.7
*SUSE Linux Enterprise Server
(SLES) 10 SP2 and higher
Xen HVM 		x64 System with: INTEL-VT or AMD-V Not Supported SLES 10 SP2 64bit DB2 9 FP4
DB2 9.5 FP1

*Microsoft Windows 2008 SP2
Hyper-V
x64 System with: INTEL-VT or AMD-V Windows 2008 Server SP2 Not Supported DB2 9.5 FP4
DB2 9.7
* Important restrictions regarding RHEL and SLES Xen Environments:
  • Only 64bit DB2 instances supported.
  • Guest VMs must be HVM mode and 64bit Linux. Paravirtual guests are not supported by DB2 at this time.
  • Guest OS distro must be within the same major version as the Host OS distro.
  • Disk I/O access must be through the 'phy:' mechanism which is used to export devices or logical volumes to the guest (therefore, no file based devices). The mechanism can be set in your xen guest's configuration file. Other access modes such as 'file:' and 'tap:aio:' are not supported by DB2 at this time.
  • Disk devices exported to guest VMs must have write caching disabled using 'hdparm -W0 (device name)'.
  • Live Migration is not supported by DB2 at this time.


* Important restrictions regarding Windows Hyper-V:

  • Quick Migration is not supported by DB2 at this time.


DB2 Supported OS Virtualization Environments for x86 and x64 Architectures
Technology Architecture Operating System Minimum DB2 Level
*Solaris Zones x64 Solaris 10 DB2 9 FP4

* Important restrictions regarding Zones:
  • DB2 versions prior to 9.7 are supported for installation on local zones only. Installation of these versions of DB2 on the global zone is not supported. This restriction does not apply to DB2 9.7.
  • Branded (or non-native) Zones are not supported.

* Important restrictions regarding WPARs and Zones:

  • DB2 versions prior to 9.7 are supported for installation on local partitions/zones only. Installation of these versions of DB2 on the global partition/zone is not supported. This restriction does not apply to DB2 9.7.
  • WPAR mobility is only supported with DB2 9.5 on minimum OS level AIX 6.1 TL04 SP1.
