HP Integrity Virtual Machines Manager 4.1 Software: User Guide

Virtual Machine Memory page). These two values can be different if for some reason Integrity
VM cannot change the memory size to the specified value.
• Memory: The amount of memory configured for the virtual machine, which is the amount
of memory required to start VM (and is modifiable as such on the Modify→ Virtual Machine
Memory page).
If dynamic memory was enabled, the configuration table displays the following fields instead:
— Memory Required to Start VM: The amount of memory needed for the virtual machine
to boot.
— Initial Target for Memory Size After Boot: The value to which Integrity VM tries to
change the virtual machine memory immediately after it boots.
— Minimum Memory Size: The lowest value to which the virtual machine can attempt
to dynamically decrease its memory while the OS is running.
— Maximum Memory Size: The highest value to which the virtual machine can attempt
to dynamically increase its memory while the OS is running.
— VM is Allowed to Control Memory Size: Indicates whether the Allow dynamic control
of memory size from the virtual machine is in effect. This control allows applications
running VM (for example, gWLM) to dynamically change the memory on the virtual
machine.
External Manager Information
• gWLM Policy: If the VM Host is being managed by gWLM and a policy has been assigned
to the virtual machine, the External Manager gWLM field displays the name of the gWLM
policy. If the VM Host is not managed by gWLM or if a policy has not been assigned to the
virtual machine, the gWLM field displays (none). With Insight Dynamics - VSE for Integrity,
if the virtual machine is managed by gWLM, the gWLM policy name is a hyperlink to gWLM.
Under HP SMH, if virtual machines are being managed by gWLM, the gWLM policy name
is text only (you cannot modify gWLM policies from HP SMH). In either case (using VM
Manager with Insight Dynamics or HP SMH), if the virtual machine is not being managed
by gWLM, this field displays (none).
• Serviceguard Package: If the virtual machine is being managed by HP Serviceguard, the
virtual machine package name is listed here. If the virtual machine is not being managed
by HP Serviceguard, this field displays (none).
VM Utilization Information
• VM Utilization Information: Displays resource utilization statistics for a virtual machine.
The utilization information is a 5-minute average that is calculated and updated on 5-minute
boundaries. If the utilization cannot be displayed, the utilization meter (bar graph) is dimmed
and a label indicates the probable cause. For a description of meter labels, see “Utilization
meter status/error information” (page 127). When VM Manager runs with Insight Dynamics
- VSE for Integrity, the utilization meters link to HP Insight Capacity Advisor software,
which records and displays utilization data. Click a meter to view the virtual machine
utilization history for virtual CPUs, memory, disk I/O, or network I/O; this feature is not
provided when using VM Manager from HP SMH. For an example utilization history screen
and more information about collecting and viewing utilization data, see Chapter 7 (page 111).
VM Authorization Information
• Authorized Administrators, Authorized Administrative Groups, Authorized Operators,
Authorized Operator Groups: These fields indicate which users and groups have
administrator or operator authority.
