Configuring Virtual Machine Options and Resources : Changing General Configuration Options

Changing General Configuration Options You can change settings on the Options tab of the Virtual Machine Properties dialog box to alter basic information about the virtual machine. Under the Options tab, you can change the General, VMware Tools, Power Management, and Advanced settings. [email protected] | Copyright © 2008 VMware, Inc. All rights reserved.

Configuring Virtual Machine Options and Resources : Changing General Configuration Options : Editing General Information on the Options Tab

Editing General Information on the Options Tab General options that can be changed include the virtual machine name and guest operating system. The current location of the virtual machine and its current “working location” (often the same as the virtual machine location) appear on this page but can’t be changed here. Moving all or part of a virtual machine, even when it is not powered on, requires reconciling the changes across the system and across the files that compose it. The Advanced option in the Relocate Virtual Machine wizard, which is accessed from the main VI Client window, lets you change the location of individual parts of the virtual machine, including the working location.

When you change the operating system type using the Version list, only the setting for the guest operating system type in the virtual machine’s configuration file is changed. The guest operating system itself is not changed. See the Basic System Administration guide and the Guest Operating System Installation Guide for information about installing the guest operating system. (Choose Help > Manuals.) When you set the guest operating system type for a new virtual machine, the VI Client chooses configuration defaults based on the guest type. Changing the guest type after the virtual machine is created does not retroactively change those settings. It affects the recommendations and setting ranges offered after the change. You might change the guest operating system, for example, if you are upgrading the guest operating system installed in the virtual machine. Note: Changing the guest operating system affects the ranges and recommendations of other settings, such as memory and number of CPUs. After changing the guest operating system type, VMware recommends clicking OK, allowing the reconfiguration task to complete, and reopening the dialog box to view new recommendations and settings.

Configuring Virtual Machine Options and Resources : Changing the Power State

Changing the Power State The basic power state options are listed in the following table. Power On

Powers up the virtual machine and boots the guest operating system if the guest operating system is installed.

Power Off/Shutdown

Stops the virtual machine until it is powered back on.

Suspend

Pauses the virtual machine activity. All transactions are frozen until you issue a Resume command.

Resume

Allows virtual machine activity to continue and releases the Suspended state.

Reset/Restart

Stops the virtual machine and restarts (reboots) it.

Power state tasks include: • Manually Powering a Virtual Machine On and Off • Suspending and Resuming a Virtual Machine • Scheduling a Power State Change for a Virtual Machine [email protected] | Copyright © 2008 VMware, Inc. All rights reserved.

Configuring Virtual Machine Options and Resources : Changing the Power State : Manually Powering a Virtual Machine On and Off

Manually Powering a Virtual Machine On and Off Prior to performing any power state changing activity on a virtual machine, you must add the virtual machine to your VMware Infrastructure environment. See Creating a Virtual Machine. To manually change the power state of a virtual machine 1.

down the operating system directly from inside the guest. Alternatively, you can change the behavior of the power button on a per-virtual machine basis by clicking the virtual machine, choosing Edit Settings > Options > VMware Tools and selecting the behavior from the Power Controls drop-down list. • Choose Inventory > Virtual Machine from the drop-down menu and choose a power option. • Right-click the virtual machine, and select the Power On or Power Off option. Note: The right- click menu on a virtual machine displays two options: Power Off and Shut Down. Power Off, sometimes called “hard” power off, is analogous to pulling the power cable on a physical machine and always works. Shut Down, or “soft” power off, leverages VMwareTools to perform a graceful shutdown of a guest operating system. In certain situations, such as when VMware Tools is not installed or the guest operating system is hung, shut down might not succeed. After the power option is selected, the VI Client displays messages in the Recent Tasks panel indicating the transition modes. [email protected] | Copyright © 2008 VMware, Inc. All rights reserved.

Configuring Virtual Machine Options and Resources : Changing the Power State : Suspending and Resuming a Virtual Machine

Suspending and Resuming a Virtual Machine You can use the suspend feature to make resources available on a short-term basis or for other situations in which you want to put a virtual machine on hold without powering it down. Conditions Inventory panel object:

Minimum required privileges:

Suspend

After you resume work and do additional work in the virtual machine, you cannot return to the state the virtual machine was in at the time you suspended it. To preserve the state of the virtual machine so you can return to it, take a snapshot. See Understanding Snapshots. The speed of the suspend and resume operations depends on how much data has changed while the virtual machine has been running. In general, the first suspend operation takes longer than later suspend operations. When you suspend a virtual machine, a file with a .vmss extension is created. This file contains the entire state of the virtual machine. When you resume the virtual machine, its state is restored from the .vmss file. To suspend a virtual machine 1.

Right-click the virtual machine in the inventory panel and click Suspend.

2.

When the VI Client finishes the suspend operation, choose File > Exit to exit the VI Client.

To resume a virtual machine that you have suspended 1.

Start the VI Client and select a virtual machine that you have suspended.

2.

Right-click the virtual machine and select Power On.

Note: Any applications you were running at the time you suspended the virtual machine are running, and the content is the same as it was when you suspended the virtual machine. [email protected] | Copyright © 2008 VMware, Inc. All rights reserved.

Specifying the CPU Identification Mask The CPU identification mask is used by VirtualCenter to determine whether a destination host is viable for migration with or without VMotion. You can make changes to the CPU identification mask to hide certain CPU features from guest software to increase the migration compatibility. You can make changes to the CPU identification mask only when the virtual machine is powered off. See the VMware Knowledge Base for more information about CPU Identification masks. Note: You rarely need to make any change to the CPU identification mask. Almost all changes are made only to the Nx bit, which advertises security-related CPU features to the guest operating system.

Setting N-Port ID Virtualization Options N-port ID virtualization (NPIV) provides the ability to share a single physical Fibre Channel HBA port among multiple virtual ports, each with unique identifiers. This allows control of virtual machine access to LUNs on a per-virtual machine basis. Each virtual port is identified by a pair of World Wide Names (WWNs): a World Wide Port

Name (WWPN) and a World Wide Node Name (WWNN). These WWNs are assigned by the VirtualCenter Server. NPIV support is subject to the following limitations: • NPIV must be enabled on the SAN switch. Contact the switch vendor for information about enabling NPIV on their devices. • NPIV is supported only for virtual machines with RDM disks. Virtual machines with regular virtual disks continue to use the WWNs of the host’s physical HBAs. • The physical HBAs on the ESX Server host must have access to a LUN using its WWNs in order for any virtual machines on that host to have access to that LUN using their NPIV WWNs. • The physical HBAs on the ESX Server host must support NPIV. If the physical HBAs do not support NPIV, the virtual machines running on that host will fall back to using the WWNs of the host’s physical HBAs for LUN access. • Each virtual machine can have up to 4 virtual ports. NPIV-enabled virtual machines are assigned exactly 4 NPIV-related WWNs, which are used to communicate with physical HBAs through virtual ports. Therefore, virtual machines can utilize up to 4 physical HBAs for NPIV purposes. To view or edit a virtual machine’s WWNs 1.

To edit the virtual machine’s WWNs, power off the virtual machine.

6.

Click OK.

Note: A virtual machine with WWNs that are already in use on the storage network is prevented from powering on. To solve this issue, generate new WWNs or remove them. Provide the WWN assignments to your SAN administrator. The administrator needs those assignments to configure virtual machine access to the LUN.

Configuring Virtual Machine VMI Paravirtualization VMI is a paravirtualization standard that enables improved performance for virtual machines capable of utilizing it. This feature is available only for versions of the Linux guest operating system that support VMI paravirtualization. Note: Enabling paravirtualization utilizes one of the virtual machine’s six PCI slots. Also, enabling paravirtualization can limit how and where the virtual machine can be migrated. Consider the following before enabling this feature: • These hosts support VMI paravirtualization: ESX Server 3.5 and greater, ESX Server 3i version 3.5 and greater, Workstation 6.x and greater. You can migrate Hardware version 4 virtual machines with paravirtualization enabled from ESX Server hosts to Workstation hosts without loss of functionality. • You can manually move a powered-off virtual machine with paravirtualization enabled to a host that does not support paravirtualization. However, this can result in reduced performance.

Configuring Virtual Machine Options and Resources : Setting Advanced Options : Specifying Virtualized MMU Settings

Specifying Virtualized MMU Settings Recent CPUs are capable of virtualizing the Memory Management Unit (MMU). The use of this capability almost always improves virtual machine performance. However, there might be cases where it is perferable not to virtualize the MMU. You can select one of the following choices: • Force the use of this capability • Forbid the use of this capability • Allow the host system determine when to use this capability.

Configuring Virtual Machine Swapfile Location By default, each virtual machine uses the virtual machine swapfile location set for the host or cluster on which it resides. See Configuring Virtual Machine Swapfile Properties for the Host and Configuring a Virtual Machine Swapfile Location for a Cluster. You can use the Virtual Machine Swapfile Location option to override the host or cluster settings and set the location for an individual virtual machine.

Configuring Virtual Machine Options and Resources : Configuring Virtual Machine Resources : Memory Resources

Memory Resources The Memory Resources page lets you allocate memory resources for a virtual machine, specifying reservations, limits, and shares. You can edit the same information on the Resource Allocation tab of the main VI Client window. Memory resource configuration is distinct from the virtual hardware memory size, which is configured on the Hardware tab. The memory resource setting determines how much of the host’s memory is allocated to a virtual machine. The virtual hardware memory size determines how much memory applications that are running inside the virtual machine have available to them. A virtual machine cannot benefit from more memory resources than its configured virtual hardware memory size. The ESX Server host caps memory resource use to the maximum useful for the virtual machine, so you can accept the default of Unlimited memory resources. Assigning a virtual machine a reservation larger than its configured memory is wasteful. The VI Client does not allow you to make such an assignment on the Resources tab. If you give a virtual machine a large reservation and then reduce its configured memory size on the Hardware tab, the reservation is reduced to match the new configured memory size.

Allowed while virtual machine is powered on?

Note: Hyperthreading technology allows a single physical processor to behave like two logical processors. While hyperthreading does not double the performance of a system, it can increase performance by better utilizing idle resources. For information about hyperthreading and VMware Infrastructure, see the Resource Management Guide (choose Help > Manuals). VMware ESX Server generally manages processor scheduling well, whether or not hyperthreading is enabled. The settings on this page are useful only for fine-grained tweaking of critical virtual machines.

Hyperthreading Sharing The Hyperthreading Sharing group provides detailed control over whether a virtual machine should be scheduled to share a physical processor core (assuming hyperthreading is enabled on the host at all). The options are: • Any – (default) The virtual CPUs of this virtual machine can freely share cores with other virtual CPUs of this or other virtual machines. • None – The virtual CPUs of this virtual machine have exclusive use of a processor core whenever they are scheduled to it. The other hyperthread of the core is “halted” while this virtual machine is using the core. • Internal – On a virtual machine with exactly two virtual processors, the two virtual processors are allowed to share one physical core (at the discretion of the ESX Server scheduler), but this virtual machine never shares a core with any other virtual machine. If this virtual machine has any other number of processors than two, this setting is the same as the None setting.

Scheduling Affinity The Scheduling Affinity group allows fine-grained control over how virtual machine CPUs are distributed across the host's physical cores (and hyperthreads if hyperthreading is enabled). This option is not allowed when the virtual machine resides on a DRS cluster, and its values are cleared when a virtual machine is migrated to a new host, because the only value of the option is in tuning the performance of a precise set of virtual machines on the same host. The check boxes for the individual processors represent physical cores if hyperthreading is disabled or logical cores (two per physical core) if hyperthreading is enabled. Checking all the boxes is the same as not applying any affinity. If you specify affinities, you must provide at least as many processor affinities as the number of virtual CPUs in the virtual machine. [email protected] | Copyright © 2008 VMware, Inc.

Configuring Virtual Machine Options and Resources : Removing and Returning Virtual Machines from VirtualCenter

Removing and Returning Virtual Machines from VirtualCenter If a virtual machine is removed from VI Client control, the link between the managed host and the virtual machine is severed. The managed host and VI Client no longer recognize the virtual machine. However, the virtual machine remains on the datastore connected to the managed host. If you have removed a virtual machine from a VirtualCenter Server but did not remove it from the managed host's datastore, you can return it to the VirtualCenter Server by using the New Virtual Machine wizard. Conditions Inventory panel object:

Inventory button > virtual machine object

Virtual machine must be powered:

OFF

To reach this panel:

Inventory > Virtual Machine > Remove from Inventory

Minimum required privileges:
