New and Changed Information in This Edition

Changes and additions to software requirements regarding VM Provider for VM Host and guests, as described in “System and Software Requirements”

Changes in information provided by the Used by column of the Create Virtual Switch screen, as described in “Creating Virtual Switches”

Support of HP-UX 11i v3 as a VM Host, including features of HP-UX 11i v3, such as long user names, hostnames, PIDs, and agile storage device naming.

Support of HP Integrity VM version 4.0 (in addition to all earlier versions of Integrity VM that are still supported).

	NOTE: This version of VM Manager is compatible with HP Integrity Virtual Machines version 4.1 but does not support the new features provided by that version of the product. The releases of an operating system that are supported on guests vary from version to version of HP Integrity Virtual Machines. For information about supported VM guest operating systems, see the version of the HP Integrity Virtual Machines Installation, Configuration, and Administration manual that corresponds to the version of HP Integrity Virtual Machines being used.

Accelerated Virtual I/O (AVIO) support for the following:

Support of legacy and agile storage device addressing, the latter being introduced with HP-UX 11i v3. Legacy addressing uses the device special file (DSF) path as defined in HP-UX 11i v2 and earlier versions of HP-UX. The new agile device model uses worldwide device identifiers (WWIDs) to uniquely identify logical unit (LUN) devices (a LUN is the logical unit that refers to the physical storage device). The WWID is a device attribute that is independent of the device’s location in a SAN or in an adapter/controller access path. With a multipath device, the WWID allows one persistent DSF and one LUN hardware path to represent the device, regardless of the number of legacy hardware paths. Therefore, an agile device address remains the same (is persistent) when changes are made to the access path. This enables VM Manager to display one DSF for each multipath device instead of displaying a separate DSF for each path to the device (as done when using the legacy addressing scheme).

The VM Manager VM Host Storage and VM Properties Storage tabs display the new agile, multipath device special file (DSF) supported with HP-UX 11i v3 VM Hosts as well as the legacy addresses. The Create Virtual Machine wizard Add Storage Device and the ModifyAdd Storage Device to Virtual Machine... screens give you the option of listing devices (that are to be added) by either their agile or their legacy addressing specification. With HP-UX 11i v2 or earlier VM Hosts, VM Manager storage device listings remain the same, showing only the legacy specifications.

Support of a browser screen for selecting a backing file or directory for a storage device being added to a new or existing virtual machine. This saves the user from having to remember the file or directory name and from potentially specifying the file names incorrectly. This feature is implemented from the Create Virtual Machine wizard's Add Storage Device screen and the ModifyAdd Storage Device to Virtual Machine screen.

When using VM Manager to add a storage device to a virtual machine, choices for file and directory backing devices can include devices entered into the hpvmdevmgmt device database without association with a particular virtual machine. This is useful, for example, to populate the database with entries for OS installation DVD images that might be used when creating and provisioning several virtual machines. When you use VM Manager to add a virtual DVD to a virtual machine, the image file shows up in the list of storage backing devices you can choose from. You do not have to type the name of the image file or browse for it.

You can make unassociated file or directory backing devices available to VM Manager if the VM Host is running HP Integrity VM version 4.0 or later. At the VM Host command line, add a file or directory to the device management database as a guest device (gdev) by specifying the hpvmdevmgmt command with the USAGE attribute either USAGE=DISK or USAGE=DVD. As a result, the VM Manager Create Virtual Machine wizard Add Storage Device and ModifyAdd Storage Device to Virtual Machine... screens include the file in the list of backing devices you can choose from. The file is listed as a backing device for either a virtual disk or a virtual DVD, depending on the value of the USAGE attribute. If you add a file to the database without specifying the USAGE attribute, the file is not included in the list of possible backing devices. If you add a directory to the database, it is included in the list as a possible backing device for a virtual DVD. Do not specify the USAGE attribute for a directory; the attribute is not needed for a directory.

To ensure that a device database entry is preserved in the database for future selection, even when the associated virtual device is removed from the virtual machine, or even when all virtual machines using the entry as a backing device are deleted from the VM Host, you can specify the PRESERVE attribute as PRESERVE=YES.

When you create a file as a backing device for a disk, specifying the size (-S) attribute with the hpvmdevmgmt command, you can ensure that the file is included in the list of possible backing devices on the previously-mentioned VM Manager screens by specifying the -A attribute as well. Specifying these two attributes automatically sets USAGE=DISK and PRESERVE=YES.

By default, the VM Manager VM Host Storage and VM Properties Storage tabs display only the specific storage devices that are being used as backing devices. For a multipath device, the default view shows only the device special file (DSF) path, as specified when the virtual storage device was created. A new Show physical host bus adapters check box available on each of these tabs allows you to change the view to include the complete storage bus structure, host bus adapters, and multipath storage configurations. The default, simpler view renders more quickly and helps you discern more easily the associations between virtual machines and devices, especially when many multipath storage devices exist on the VM Host. The complex view displays all DSF versions of the same device, including (on an HP-UX 11i v3 VM Host) the persistent DSF. The complex view is identical to the view displayed by the VM Host Storage and VM Properties Storage tabs in earlier versions of VM Manager.

Support for HP Integrity VM entitlement caps, if supported by the version of Integrity VM running on the VM Host. The VM Manager Create Virtual Machine wizard's Specify Processors screen and the ModifyVirtual Machine vCPU Entitlement screen allow you to specify a cap for the vCPU or specific processor speed entitlement.

Support for guests running up to 8 virtual CPUs (vCPUs) and for selection of a minimum and maximum of virtual CPUs, if supported by the version of Integrity VM running on the VM Host. With HP Integrity Virtual Machines Version 4.0, the VM Manager Create Virtual Machine wizard's Specify Processors screen and the ModifyVirtual Machine Processor Count screen allow you to specify a minimum and maximum number of vCPUs as you create or modify a virtual machine.

Support for a VM graceful stop timeout value that specifies the amount of time HP Integrity VM waits for I/O activity to complete before stopping a virtual machine (if this feature is supported by the version of Integrity VM running on the VM Host). The value is displayed on the VM Manager VM Properties General tab but must be set by using the hpvmmodify command at the VM Host command line.

Improved VM Properties General tab, which includes better organization of information and more details.

Improved Create Virtual Machine wizard Next Steps screen, with information organized more clearly and in proper order.

A new section that describes how to use VM Manager to enable collection of Capacity Advisor utilization data, view utilization data, and create historical utilization reports; see “Collecting and Viewing Utilization Data”.
