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 SIM.
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. VM Manager obtains information about Integrity VM resources through Web-Based Enterprise Management (WBEM) providers installed on the VM Host and on virtual machines (guest OSes).
Figure 1-1 VM Manager with HP SMH Using VM Manager with HP SMH VM Host HP SMH VM Manager Browser WBEM VM VM VM VM VM • HP Insight Dynamics - VSE for Integrity VM Manager is installed as part of Insight Dynamics - VSE for Integrity that runs under HP Systems Insight Manager software (HP SIM) on a server reserved for use as a central management server (CMS). The CMS can run on HP-UX or Windows platforms.

— automated workload management policies across multiple servers, and provides centralized monitoring and reporting and improved server utilization to assist in meeting your service level objectives. Using VM Manager with Insight Dynamics - VSE for Integrity, you can create, view, and modify gWLM policies for virtual machines. For more information, see “Using the Policy menu” (page 84).
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 WBEM provider components are the VM Provider and the Utilization Provider: • 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.
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 VSE-OE or DC-OE.
Setting WBEM credentials in HP SIM 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. You can set credentials in HP SIM for a global configuration across multiple systems by selecting Options→Protocol Settings→Global Protocol Settings...
Figure 2-1 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.
device. For a 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.
NOTE: Copy the certificate file to a temporary directory (not to the sslshare directory) on the VM Host. Do not overwrite the existing cert.pem or server.pem file in the sslshare directory on the VM Host. 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.
3 Accessing and Navigating VM Manager You access VM Manager through a web browser. This chapter explains how to access VM Manager from the HP SIM/Insight Dynamics - VSE for Integrity Virtualization Manager 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 125).
Figure 3-2 Virtualization Manager Visualization tab 2. The first time you start Virtualization Manager, the Visualization tab appears with the default Physical and Virtual perspective, which shows all physical and virtual nodes in graphical compartments. When you start Virtualization Manager 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...
Figure 3-3 Selecting Virtual Machine perspective 3. On the Virtualization Manager Visualization tab, select the VM Host or virtual machine that you want to manage. For example, in the Integrity VM representation shown in Figure 3-4 (a closeup from the screen shown in Figure 3-3 (page 23)), you can select VM Host system chili3 by clicking the monitor icon beneath the VM Host name. (If you hover your cursor over the icon, a pop-up pane displays explanatory text.
Accessing VM Manager from HP SMH To use all the VM Manager facilities (view all screens and perform all menu actions), you must log in to HP SMH with Administrator privileges. To access VM Manager from HP SMH, follow these steps: 1. On the SMH Home page, click Tools. NOTE: SMH GUI sessions stop after the session timeout period elapses without any user activity (by default, the session timeout period is 15 minutes). With HP SMH Version 2.2.
NOTE: When you access VM Manager for the first time from HP SMH, you might encounter an End User License Agreement (EULA). You must accept this agreement to continue using the VM Manager product. Figure 3-5 HP SMH: accessing VM Manager If you have already saved WBEM credentials for each virtual machine, selecting Integrity Virtual Machines Manager displays the VM Host General tab as shown in Figure 3-6.
Figure 3-6 HP SMH: VM Host General tab If you have not set and saved WBEM credentials for each virtual machine, the Set WBEM Credentials page is displayed first (instead of the VM Host General tab). An example of the Set WBEM Credentials page is shown in Figure 2-1. Enter the appropriate information and click OK, or click Cancel to skip this step and advance to the VM Manager VM Host General tab. For more information about setting WBEM credentials, see “Setting security credentials” (page 15).

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.
NOTE: An up-to-date version of the WBEM Utilization Provider (UP) must be installed on the virtual machine to enable HP Insight Capacity Advisor software 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.
provides benefits especially for multipath devices. With legacy addressing, the screen lists one entry for each path to a storage device that has multiple paths. With agile addressing, the screen lists only one entry for each multipath storage device. To change the addressing scheme for viewing, select the appropriate addressing scheme. If the VM Host runs an earlier version of HP-UX, you are not given a choice: the table lists devices by the legacy addressing scheme only.
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.
NOTE: Depending on the settings in the virtual machine's Extensible Firmware Interface (EFI), starting a virtual machine might not boot the operating system. For more information, see “Creating virtual machines” (page 87). Once a virtual machine is started, the resources assigned to the virtual machine are allocated for its use. The VM Host ensures that the resources required by the virtual machine are available in the current VM Host system environment.
Figure 6-2 Stop Virtual Machine page 4. In the screen example shown in Figure 6-2, 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 6-3 Restart Virtual Machine page 4. In the screen example shown in Figure 6-3, 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 96).
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 96).
• • 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 59) and “VM Host Virtual Machines tab” (page 36).
NOTE: The Tools→Migrate Virtual Machine... option is enabled from any VM Properties view or from any tab on which one or more virtual machines are selected. Figure 6-4 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.
NOTE: If the source or target VM Host is not enabled and licensed for online migration, or the virtual machine is not enabled for online migration, you can migrate the virtual machine offline. Stop the virtual machine and then retry migrating it. Figure 6-5 Migrate Virtual Machine: Step 2 of 2 6. Inspect the commands. If they suit your needs and you want to go ahead with the migration, click Finish.
To create a vswitch, select Create→Virtual Switch from the VM Manager menu. This displays a page similar to that shown in Figure 6-6. Figure 6-6 Create Virtual Switch page The table on the screen shown in Figure 6-6 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.
• • Hardware path: Shows the hardware path associated with the LAN interface. Supports AVIO: Shows whether the physical backing device supports Accelerated Virtual Input/Output (AVIO). For each virtual machine containing an AVIO device, the VM Host OS and the guest OS must support AVIO. In addition, HP strongly recommends that AVIO components (such as drivers and libraries) on the virtual machine and VM Host be updated to the latest release of the OS.
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 no physical network device on the VM Host is chosen, the vswitch is a local vswitch. A local vswitch has no connection with any physical network device on the VM Host. Virtual machine virtual network interface cards (vNICs) can communicate only with other virtual machines on the same VM Host that are connected to the same local vswitch. 4.
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. Deleting a storage device does not affect data on that device (files or data are not removed from the device). NOTE: You cannot remove a device that is currently being used by the guest OS or if I/O is outstanding.
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 7-1. Using VM Manager with Insight Dynamics - VSE for Integrity, you can click a meter to view a more detailed historical data report provided by HP Insight Capacity Advisor software.
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 111) have been met. • Utilization meters provided by VM Manager tabs. Table 7-1 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.
Table 7-1 Utilization meters available on VM Manager tabs VM Manager Tab Utilization Metrics CPU (%) Memory (%) Network I/O (throughput) Storage I/O (throughput) VM Host only VM Host only VM Host only VM Host only Per VM only VM Host Virtual VM Host CPU utilization per VM Machines VM vCPU utilization Per VM only Per VM only VM Host Network VM Host (Physical Network Interfaces column) VM (Virtual Network Interfaces column) VM Host General VM Host (Physical Storage column) VM (Virtual Storage c
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 7-2 View Capacity Advisor data screen: upper half Viewing utilization data 115
Figure 7-3 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 Insight Capacity Advisor software 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 Insight Dynamics; 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.
