HP UX vPars and Integrity VM v6 manual Automatic Memory Reallocation

If you have enabled dynamic memory and you want automatic memory reallocation, you can enable the AMR memory control. You can also select the AMR chunk size for the virtual machine.

Automatic Memory Reallocation

You can automatically reallocate memory for virtual machines that have dynamic memory enabled. The Enable AMR memory control check box is selected by default. Provide the following information:

•Dynamic memory entitlement: the memory allotted to a virtual machine. This value must be equal to or greater than the minimum memory size of that virtual machine. The default value is 512 MB. The maximum value must not be greater than the initial target memory size.

•AMR Chunk Size: the additional memory size that a virtual machine can use up to in case of an increase in workload. This is optional. The default value is 256 MB. Minimum and maximum values are 32 MB and 600 MB respectively.

NOTE: The Enable AMR memory control and Allow dynamic control of memory size from the VM options cannot be enabled at the same time.

NOTE: An up-to-date version of the WBEM Utilization Provider (UP) must be installed on the virtual machine to enable HP Capacity Advisor and the memory utilization meters in VM Manager and Integrity VM to reflect the dynamic change in memory. For information about verifying and installing software on virtual machines, see “System and software requirements” (page 13) and the HP Integrity Virtual Machines documentation.

4.Specify Network Devices

To add a virtual network device, click Add Network Device... on the first network device screen. This brings up the Add Network Device screen. First, select the type of virtual network interface card. The default is AVIO LAN device. You can select Accelerated Virtual Input/Output (AVIO) device type if AVIO is supported by the version of Integrity VM (Version 3.5 or later) on the VM Host and by the intended guest OS. For Windows and Linux guests, support for AVIO virtual network devices requires that compatible Windows and Linux drivers be installed on the guest and additional patches be installed on the Integrity VM Version 3.5 or later. The OpenVMS guest OS supports only the AVIO interface.

For HP-UX, HP recommends that you install the latest AVIO components for both the VM Host and the guest; however, updating both guest and host components at the same time is not mandatory. Updating both components ensures that you always receive the latest bug fixes for a complete solution. Always check the following software depot website for the latest version of AVIO software (search for “HPVM AVIO”):

http://software.hp.com

The guest AVIO drivers are included in the VMGuestSW bundle available from the software depot website. Search for the bundle and make sure you install the latest version.

For more information, see the HP Integrity Virtual Machines documentation.

After you select the virtual network interface type, select the virtual switch from the list provided or create a virtual switch. To provide network access for the virtual machine, a virtual switch is necessary.

NOTE: VM Manager does not automatically update its display of I/O while the Create Virtual Machine wizard is being used. If the network or storage I/O configuration on the VM Host changes while the Create Virtual Machine wizard is in use, update the configuration changes displayed by the wizard by clicking the Refresh Data link.
