1 Introduction This document helps you understand and use Integrity Virtual Machines Manager. The audience for this document includes system administrators and others responsible for maintaining an Integrity VM host and its virtual machines. You should be familiar with the HP Integrity Virtual Machines (Integrity VM) product and HP-UX system administration using either HP SMH or HP Systems Insight Manager.
configure, and evaluate virtual machines, and to monitor and evaluate data and resources at the level of the VM Host. You can view all of a VM Host's virtual machines and their assigned resources, and you can view all resources assigned to a specific virtual machine or virtual switch. For example, VM Manager provides graphical views of virtual-to-physical network and storage devices so that you can view I/O data, including resource utilization information.
Figure 1 VM Manager with HP SMH • HP Matrix Operating Environment for HP-UX VM Manager is installed as part of Matrix Operating Environment for HP-UX that runs under HP Systems Insight Manager on a server reserved for use as a central management server (CMS). The CMS can run on HP-UX or Windows platforms. HP Systems Insight Manager serves as the central point of administration for complete resource-lifecycle management for multi-OS environments.
Figure 2 VM Manager with HP Systems Insight Manager and the HP Matrix Operating Environment for HP-UX In this environment, you can use VM Manager in seamless integration with other Matrix Operating Environment for HP-UX components. These interlinking components enhance the functionality and flexibility of your virtual server environment. For example: 10 ◦ HP Matrix OE visualization provides a framework for visualizing your Virtual Server Environment.
utilization of server resources. From VM Manager, you can cause Capacity Advisor to collect and display historical data for a VM Host or selected virtual machines. Certain VM Manager views include utilization meters (bar graphs) that display current utilization data for a resource; you can click the meter to view a screen that provides more detailed historical data. (These meters are visible when using VM Manager with HP SMH, but you cannot click them to obtain a Capacity Advisor report.
2 Installing VM Manager This chapter discusses how to install VM Manager on your system or on the systems you will manage, including setup and software requirements, licensing requirements, and how to set WBEM security credentials. System and software requirements System requirements for the VM Host and virtual machines are described in the HP Integrity Virtual Machines Installation, Configuration, and Administration manual.
• The VM Provider provides VM Host and guest configuration data. This information is delivered using WBEM. To use Integrity Virtual Machines Manager to view configuration data, install the VM Provider (VMProvider bundle) that is provided with Integrity VM. Install the VM Provider on the VM Host and on each virtual machine when you install the HP Integrity Virtual Machines product. If you upgrade Integrity VM, be sure to keep the VM Provider up to date, too.
To determine the version of VM Manager currently installed, enter the following command: #/usr/sbin/swlist VMMGR NOTE: Beginning with the HP-UX 11i v3 March 2009 Operating Environment Update Release (OEUR), you can optionally install VM Manager on HP SMH as part of the Matrix OE or DC-OE.
The method for setting WBEM credentials depends on whether you are using HP Systems Insight Manager or HP SMH. Setting WBEM credentials in HP Systems Insight Manager Any virtual machines that are not managed nodes do not have any credentials available, and VM Manager cannot contact them. These machines are displayed, but some of the information that can be gathered from the managed nodes is not displayed for non-managed nodes.
Figure 3 HP SMH: Set WBEM Credentials page On this page, you can set one user name and password combination for all virtual machines, or you can set them individually for one or more virtual machines. If you set the credentials for some but not all of the individual systems, VM Manager does not collect utilization data and operating system information for the excluded systems. You can also save the user name and password entries in obscured format in the file system.
If you require the additional security provided by certificate validation, you can turn on SSL certificate validation by checking the Require trusted certificates check box. If this box is checked, you must store the valid certificates for the virtual machines in a keystore on the VM Host to indicate that connections to those virtual machines are trusted; otherwise, some information is not displayed by VM Manager. For example, if a certificate is missing, utilization meters are labeled No Data.
virtual machine with valid credentials, VM Manager displays I/O utilization data for each virtual storage device and for VM aggregated storage interfaces. • Virtual LAN (VLAN) interface name and status on the Network tab: This status is displayed for a virtual machine with valid credentials, but invalid credentials will return an unknown LAN status and utilization. It might display whatever information is available, for example, the bus, dev, or the fcn number for the VLAN interface.
3. To import the certificate file, enter the following command on the VM Host: $ JAVA_HOME/bin/keytool -import -alias server_hostname \ -file cert.pem \ -keystore /etc/opt/hp/sslshare/parmgr.keystore Discovering data when setting new WBEM credentials When you set new WBEM credentials from the VM Manager Modify menu and click OK, the page to which you return is updated using the new credentials.
3 Accessing and Navigating VM Manager You access VM Manager through a web browser. This chapter explains how to access VM Manager from the Systems Insight Manager/Matrix Operating Environment for HP-UX Matrix OE visualization Visualization tab and from HP SMH. This chapter also explains how to access VM Manager help. Information about possible access failures and the messages that might be seen is included in Appendix A (page 115).
Figure 5 HP Matrix OE visualization Visualization tab 2. The first time you start HP Matrix OE visualization, the Visualization tab appears with the default Physical and Virtual perspective, which shows all physical and virtual nodes in graphical compartments. When you start HP Matrix OE visualization any time after, the software checks whether you had previously set a default view by modifying user preferences (modify user preferences by selecting Configure→User Preferences...
3. On the HP Matrix OE visualization Visualization tab, select the VM Host or virtual machine that you want to manage.

6 Working with virtual machines This chapter describes tasks you can perform to create and manage virtual machines and their resources. Planning virtual machines To achieve your goals using virtual machines, plan the configuration of each virtual machine by assessing its requirements for resources on the HP Integrity system on which it will run.
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.
5. Each virtual storage device is backed by physical storage in the VM Host system. A physical storage device can be a disk device, a logical volume, a DVD or CD, a DVD writer (burner), a tape device, a tape changer, an existing file (a file or directory being used as the backing storage device for a virtual storage device of an already-existing virtual machine on the VM Host), or a new file that VM Manager allows you to create as a backing storage device for a virtual disk (Virtual FileDisk).
NOTE: The list can include file and directory backing devices that have not been associated with a particular virtual machine, or that were associated with virtual machines that have been removed or from which the associated virtual devices have been removed. You can make these devices available to VM Manager by adding them to the Integrity VM device database.
At this step, you can still cancel (exit the Create Virtual Machine wizard) or return to modify previous steps in the wizard. When you click Finish, the wizard executes the hpvmcreate commands displayed in the Command Preview area: • If the Create VM even if resources are insufficient, missing or unavailable check box is not selected, the wizard executes the first of two commands (hpvmcreate -s) to check for resource availability and other issues without actually creating the virtual machine.
NOTE: Any devices added using the Create Virtual Machine wizard are not functional on the virtual machine until the new virtual machine is started. Certain devices are not seen in a VM Manager Storage tab until the virtual machine is started. You can configure the virtual machine's Extensible Firmware Interface (EFI) to boot the guest OS automatically when the virtual machine is started (powered on). Configure EFI when the virtual machine has been started and before booting the OS.
NOTE: If the virtual machine is being managed by gWLM, you cannot modify the vCPU entitlement. When you access the Virtual Machine vCPU Entitlement page, the following error message is displayed, where virtual-machine-name is the name of the virtual machine: The processor entitlement for VM virtual-machine-name cannot be modified because it is being managed by gWLM. To adjust the processor entitlement for this VM, use gWLM to change the policy associated with this VM.
NOTE: The list of possible backing devices for the storage device you want to add can include file and directory backing devices that have not been associated with a particular virtual machine, or that were associated with virtual machines that have been removed or from which the associated virtual devices have been removed. You can create a file as a backing storage device for a virtual disk.
NOTE: You cannot start a virtual machine that is currently migrating online. You must wait until migration completes. If the selected virtual machine has migrated to another VM Host (the target), the virtual machine (on the source VM Host) is in the Not Runnable state: you cannot start a virtual machine in this state. To start one or more selected virtual machines, perform the following steps. 1. 2.
the current VM Host system environment. If the virtual machine cannot be started, VM Manager displays messages indicating which resources cannot currently be provided. For information about possible reasons that a virtual machine might not start, see “Troubleshooting virtual machine problems” (page 118). Stopping virtual machines To stop one or more virtual machines, perform the following steps. This action allows you to stop the virtual hardware for a virtual machine.
Figure 51 Stop Virtual Machine page 4. In the screen example shown in Figure 51, two of the selected virtual machines are going to be stopped (bitsy00 and bitsy01), while two are already stopped (vm001 and vms). The screen reports that the OS is running on one of the virtual machines and advises you to shut down the OS on that machine before stopping it. The How to Stop options allow you to control how a virtual machine is stopped: • Graceful. This is the default.
Restarting virtual machines When you choose to restart one or more virtual machines, VM Manager stops a virtual machine that is already started, and then restarts it; if a machine is stopped, VM Manager starts it. Once a virtual machine starts, the resources assigned to the virtual machine are allocated for its use.
Figure 52 Restart Virtual Machine page 4. In the screen example shown in Figure 52, two virtual machines will be stopped (gracefully) and restarted. A message indicates that these machines have an active operating system that should be shut down prior to stopping the virtual machine. The How to Stop options allow you to control whether the virtual machines are stopped gracefully (the default) or forcefully. For a description of each stop option, see “Stopping virtual machines” (page 88).
Virtual Machines tab. From tabs that list and allow selection of multiple virtual machines, you can simultaneously delete multiple virtual machines that are selected. NOTE: Before deleting a virtual machine, you must first stop the virtual machine (put it in the Off state). For instructions, see the section “Stopping virtual machines” (page 88).
• Balance VM Host workloads • Optimize physical resource utilization Online migration of virtual machines enables a higher level of workload-to-resource alignment, flexibility, and agility.
Some of the basic migration requirements include the following; for complete details, see the HP Integrity Virtual Machines Installation, Configuration, and Administration manual: • For online migration, the source and target hosts must be running HP Integrity VM Version 4.1 or later. • The source and target hosts must conform to the operating system requirements, and both must be able to provide the allocated resources to the virtual machine being migrated.
Migration status and error notification The migration status of a virtual machine — including the direction of migration, percentage completion per phase (for online migration only), and error messages — is displayed on the VM Properties General tab. The VM Host Virtual Machines tab also indicates migration status (use this tab to monitor the migration of multiple virtual machines). For more information, see “VM Properties General tab” (page 57) and “VM Host Virtual Machines tab” (page 33).
Figure 53 Migrate Virtual Machine: Step 1 of 2 3. 4. 5. Specify the target VM Host name, alias, or IP address. The target must be a valid VM Host and must be accessible by the source VM Host. If you intend to migrate a virtual machine online, this VM Host must be licensed and enabled for online migration. If you want the virtual machine configuration removed from your source VM Host after the migration completes, select the check box provided for that purpose.
Figure 54 Migrate Virtual Machine: Step 2 of 2 7. Inspect the commands. If they suit your needs and you want to go ahead with the migration, click Finish. If you want to tailor the commands to be used for migrating the selected virtual machines, you can enter the desired commands manually on the VM Host.
Figure 55 Virtual Machine Suspend 3. The Command Preview area shows the commands that Integrity VM performs to suspend the virtual machine. Click OK. The virtual machine is suspended and the Virtual Machines tab is displayed. You can view the status as Sp in the OS column against the selected virtual machine, as shown in Figure 56. Figure 56 Suspend status Resuming virtual machines A virtual machine can be resumed only if it is in a suspended (SP) state.
• The server has insufficient CPU resources. • The server has insufficient swap resources. • Another virtual machine is using a specified nonshared backing device. • The server is using a specified backing device. • A specified backing device does not exist. • A specified vswitch is not available. • The vswitch must be created using the hpvmnet command before the guests using it can be resumed. • The specified MAC address is in use. • The specified guest is a distributed guest.
1. Select Tools VM Move Suspend. The screen to specify the new directory is displayed, as shown in Figure 58 Figure 58 Virtual Machine move suspend 2. To change the default directly, select the Specified directory option and click Browse. The screen listing all the directories is displayed, as shown in Figure 59. Figure 59 Virtual machine browse directory 3. 4. Select a directory and click Select. The screen goes back to the VM Move Suspend page.
Figure 60 Create Virtual Switch page The table on the screen shown in Figure 60 displays the following information: • LAN interface: Shows the physical LAN interface to which a vswitch can be attached. The “(none)” entry indicates that the vswitch is local, meaning that it not connected to a LAN interface. Communication over such a vswitch does not go out on the physical network and is useful only for communicating between virtual machines.
components (such as drivers and libraries) on the virtual machine and VM Host be updated to the latest release of the OS. If the virtual machine OS is Windows or Linux, install additional AVIO-compatible drivers on the VM Host and virtual machine. 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.
• Any physical network cards (adapters) configured on the VM Host • Any APA (Automatic Port Aggregation) configured on the VM Host The display shows the APA name in one column and the individual devices or cards in the next column; however, the letters "APA" do not appear in either column. In HP-UX, any LAN port with port number 900 or greater is an APA (for example, lan900 or lan901). • None This creates a local vswitch.
When you delete a device from a virtual machine, it is disassociated from that virtual machine, allowing the device to be used by another virtual machine on the VM Host. Deleted devices remain active on a virtual machine that is running; the devices are removed once you restart the virtual machine. Storage devices that you can delete include virtual disks and DVDs as well as attached tapes, burners, and changers.
7 Collecting and viewing utilization data Certain VM Manager views include utilization meters (bar graphs) that display current utilization data for a resource. For example, the VM Host Virtual Machines tab includes several utilization meters for each virtual machine listed, as shown in Figure 61. Using VM Manager with Matrix Operating Environment for HP-UX, you can click a meter to view a more detailed historical data report provided by HP Capacity Advisor.
Viewing utilization data VM Manager provides the following options for viewing utilization data. These assume the prerequisites discussed in “Enabling collection of utilization data” (page 105) have been met. • Utilization meters provided by VM Manager tabs. Table 12 lists the meters provided by VM Manager tabs. Utilization meters display current utilization data for the associated resource. The utilization information is a 5-minute average that is calculated and updated on 5-minute boundaries.
NOTE: Data reported by certain VM Manager CPU utilization meters might vary from the data collected by Capacity Advisor as displayed in the Profile Viewer and historical utilization reports. The data from VM Manager meters is reliable for most purposes. For capacity planning, refer to the data collected by the Capacity Advisor Profile Viewer and historical utilization reports.
Figure 62 View Capacity Advisor data screen: upper half 108 Collecting and viewing utilization data
Figure 63 View Capacity Advisor data screen: lower half The data collection view is provided by the Capacity Advisor Profile Viewer. The Profile Viewer displays historical utilization data along with additional information you provide. The Profile Viewer also enables you to examine different time intervals and different categories of data. In the Capacity Advisor graphs, you can view utilization data for both CPUs and memory.
Creating a historical utilization data report To use HP Capacity Advisor to create a historical utilization report that includes data for the target workloads, systems, complexes, or scenarios you specify, select the Tools→Capacity Advisor Historic Report menu item from the VM Manager menu bar. This menu item is available only when you use VM Manager with Matrix Operating Environment; it is not available when using VM Manager through HP SMH.
8 Viewing logs and version information Viewing Integrity VM Host and VM logs You can view the events logged by Integrity VM pertaining to the VM Host and all guests by selecting View→Integrity VM log for VM Host... from the VM Manager menu bar. This gives a display similar to that created by the hpvmstatus -e command (used at the Integrity VM CLI), except VM Manager limits the display to the most recent 1000 log lines.

• No Comm. indicates that VM Manager is unable to communicate with the WBEM provider running on a virtual machine. Hover the cursor over the meter to display an exception error message identifying the problem. A common reason for the No Comm. label to be displayed is a problem with trusted certificates.
are insufficient, missing or unavailable check box is selected on the Create Virtual Machines wizard Summary page, you can still have VM Manager create the virtual machine. You will have to correct the conditions prior to starting the virtual machine. • Failure starting a virtual machine The most likely cause for a virtual machine failing to start is missing, insufficient, or unavailable resources. Make sure the required resources are made available.
The response “HPVMProviderModule OK” indicates the VM Provider is running. Any other response indicates it is not running.
