Adding an Inventory Object : VMware Infrastructure Client Inventory Objects

VMware Infrastructure Client Inventory Objects When the VI Client is connected to an ESX Server host, the inventory root is the host itself. Contained objects include resource pools and virtual machines. Clusters, folders, datacenters, networks, and datastores do not appear when the VI Client is connected directly to a host. They appear only when the VI Client is connected to a VirtualCenter Server. The VMware Infrastructure Client objects are as follows: Root folder – In VirtualCenter Server only. (In ESX Server, the root is always the host itself.) Inventory root folders correspond to the four Inventory views that you can select from the drop-down list on the right of the Inventory button in the navigation bar. Child objects to the root folder are datacenters and subfolders, and from there all the content of the VirtualCenter inventory. You cannot add or remove the root folder. Folders – In VirtualCenter Server only. A top level structure that can contain other folders, datacenters, clusters, virtual machines, templates, and hosts. The Networks and Datastores views do not contain subfolders below the root folder. Note: The privileges associated with a folder propagate to the objects within that folder. For information about privileges, see Working with Users, Groups, Roles, and Permissions. Datacenters – In VirtualCenter Server only. A datacenter can contain folders, clusters, and hosts in the Hosts & Clusters view. In the Networks or Datastores view, the datacenters contain the virtual machines, templates, networks, and datastores associated with the managed hosts. All actions performed on managed hosts and virtual machines are applied within their datacenter. Within a datacenter, you can monitor and manage virtual machines separately from their hosts and use VMotion (an optional add-on feature) to migrate powered-on virtual machines. You can migrate powered-off or suspended virtual machines between datacenters. For more information about migration, see Migrating a Virtual Machine. Clusters – In VirtualCenter Server only. A cluster is a collection of ESX Server hosts and associated virtual machines with shared resources and a shared management interface. You can enable the following cluster features if your system is licensed for them: • VMware HA allows VirtualCenter to migrate and restart a virtual machine when a host fails.

• VMware DRS monitors the VirtualCenter environment, makes initial placement recommendations, makes power-saving recommendations, makes virtual machine migration recommendations, and enables VirtualCenter to automatically place and migrate virtual machines on hosts to attain the best use of cluster resources. Hosts – Hosts are systems running ESX Server. The host is the default top structure when a VI Client is connected to a standalone ESX Server host. When the VirtualCenter Server is connected to the VI Client, all ESX Server hosts registered with VirtualCenter are referred to as hosts. An ESX Server host that is not part of a cluster is referred to as a standalone host. Resource pools – Available on ESX Server hosts and through a VirtualCenter Server. Used to allocate host-provided CPU and memory to the virtual machines resident on the host. Virtual machines – Located within a host, cluster, or resource pool. You can move virtual machines between hosts or clusters. When you add a virtual machine to a cluster or resource pool, you must specify a designated target host. Networks – In VirtualCenter Server only. A network is an alias that unites the named networks of multiple hosts. Networks are discovered when hosts are added to the VMware Infrastructure environment. You can remove them from the VMware Infrastructure environment, but you cannot add new ones through the VI Client. Datastores – In VirtualCenter Server only. Datastores are discovered when ESX Server hosts are added to the VMware Infrastructure environment. This includes the discovery of datastores that are local to the managed ESX Server host as well as datastores on a SAN or NAS. You can remove them from the VMware Infrastructure environment, but you cannot add new ones through the VI Client. [email protected] | Copyright © 2008 VMware, Inc. All rights reserved.

Adding an Inventory Object : VMware Infrastructure Client Inventory Objects : Parent/Child Objects Relationship

Parent/Child Objects Relationship The following table shows which child objects are allowed for each parent object. A folder cannot contain hosts and virtual machines (or templates) as child objects on a sibling level. In the Hosts & Clusters view, a folder displays hosts as the child objects. In the Virtual Machines & Templates view, it displays virtual machines and templates as the child objects. You must specify a designated target host when you add a virtual machine or template to a cluster or resource pool. Parent Object

2.

Connects to the managed host. Verifies that the managed host is not already being managed. If it is being managed on another datacenter, a message appears.

3.

Reads the number of processors on the managed host and allocates the appropriate number of licenses. The number of processors is stored in the VirtualCenter database and is verified on each managed host reconnection and VirtualCenter startup. Newer processors have two CPU cores in each processor package. Systems with dualcore processors must use ESX Server 2.5.2 or greater. VirtualCenter licenses are issued by pairs of processor packages, not by processor cores. If the system is using two dualcore processors or two single-core processors, the system requires a single 2-processor VirtualCenter license.

4.

Verifies that the managed host version is supported. If it is not supported, VirtualCenter checks whether the current version can be upgraded. If the managed host version can be upgraded, VirtualCenter prompts you to perform an upgrade.

5.

Minimum required privileges:

Host > Inventory > Create Cluster Host > Inventory > Modify Cluster

To create a cluster by using the New Cluster wizard 1.

In the inventory panel, click the datacenter to place the cluster in.

2.

Choose File > New > Cluster.

3.

On the first page in the New Cluster wizard, configure the cluster features: • Name – Name of the cluster. Specify a name to continue with cluster creation. • VMware HA – If selected, VirtualCenter automatically migrates and restarts virtual machines on a different host when a host fails. • VMware DRS – If selected, VirtualCenter starts collecting the load distribution information for the virtual machines. Depending on the settings in the next page, VirtualCenter either uses the information it collects to automatically migrate virtual machines to attain the best use of cluster resources, or displays migration recommendations, allowing administrators control over the migrations to be performed. You can also leave both options unselected and edit cluster features later.

4.

Click Next.

5.

If you chose the VMware DRS option in the first screen of the wizard, the DRS page lets you select the level of automation: • Manual – When you power on a virtual machine, a list of recommended hosts appears. When the cluster becomes unbalanced, recommendations for virtual machine migration appear. Note: If you power on multiple virtual machines simultaneously, a list of recommended hosts does not appear at power-on time. • Partially automated – When you power on a virtual machine, DRS places it on the best-suited host. When the cluster becomes unbalanced, recommendations for virtual machine migration appear. • Fully automated – When you power on a virtual machine, DRS places it on the bestsuited host. When the cluster becomes unbalanced, DRS migrates virtual machines from overused hosts to underused hosts to ensure a balanced use of cluster resources. You can set the migration threshold to determine how quickly virtual machines are migrated. Move the slider along the scale from Conservative to Aggressive. See Migration Threshold Levels.

6.

Click Next.

7.

If you chose the VMware HA option, the HA screen lets you set the following options: • Admission Control—Number of host failures the cluster can tolerate– Lets you specify the maximum number of host failures that you can recover from or to guarantee failover for.

they violate availability constraints. As a rule, the cluster reserves resources to allow failover for all virtual machines on the specified number of hosts. If you expect that you will not usually power on all virtual machines, you might make admission control less strict. If you do, the cluster icon turns red and failover is no longer guaranteed. • VM restart priority – Specifies the default restart priority for virtual machines in this cluster. See Configuring HA Settings. • Host isolation response – Specifies the default Host isolation response for virtual machines in this cluster. See Configuring HA Settings. • Virtual Machine Monitoring – Enables and specifies the Monitoring Sensitivity setting (High, Medium, Low) for monitoring virtual machine heartbeats. 8.

Click Next.

9.

Configure the virtual machine swapfile location for the cluster: • Select Store the swapfile in the same directory as the virtual machine to store the swapfile in the same directory as the virtual machine configuration file. • Select Store the swapfile in the datastore specified by the host to store the swapfile in the location specified in the host configuration. If you cannot store the swapfile in the datastore that the host specifies, the swapfile is stored in the same folder as the virtual machine.

10. Click Next. 11. Review the configuration of the new cluster, and make any needed changes to the appropriate page 12. Click Finish. For more information on VMware clusters, HA, and DRS, see the Resource Management Guide (choose Help > Manuals).

Migration Threshold Levels Migration threshold levels determine how quickly virtual machines are migrated. Level

Applies

Level 1, Most Conservative

Adding an Inventory Object : Editing a Cluster : Configuring HA Settings

Configuring HA Settings You can use the Cluster Settings dialog box to configure settings for VMware HA. To configure VMware HA settings 1.

In the Cluster Settings dialog box, select the General option.

2.

Select Enable VMware HA.

3.

Select the VMware HA option and set the following parameters: • Admission Control—Number of host failures the cluster can tolerate – Specifies the maximum number of host failures that you can recover from or to guarantee failover for. VirtualCenter allows a maximum of 4. • Admission Control – Determines whether virtual machines can be started if they violate availability constraints. As a rule, the cluster reserves resources to allow failover for all virtual machines on the specified number of hosts. If you think that you will not usually power on all virtual machines, you might make admission control less strict. • VM restart priority – Specifies the default restart priority for virtual machines in this cluster. This setting indicates the relative priority for restarting the virtual machine in case of host failure. Higher priority virtual machines are started first. This priority applies only on a per-host basis. If multiple hosts fail, VirtualCenter first migrates all

virtual machines from the first host in order of priority, then all virtual machines from the second host in order of priority, and so on.You can customize this property for individual virtual machines. See Customizing HA for Virtual Machines. • Host isolation response – Host isolation response specifies what the ESX Server host that has lost connection with its cluster should do with running virtual machines. By default, each virtual machine is left powered on if the host becomes isolated. You can customize this property for individual virtual machines. See Customizing HA for Virtual Machines. You can choose from the following options for the Host isolation response: Power off VM – The virtual machine powers off if the host can no longer communicate with other hosts in the cluster. Leave VM powered on – The virtual machine on an isolated host continues to run even if the host can no longer communicate with other hosts in the cluster. Shut down VM – The virtual machine shuts down its guest operating system before it powers off. This results in a slower failover time, compared to the Power off VM option, but also ensures greater data consistency. • Virtual Machine Monitoring – Enables and specifies the Monitoring sensitivity setting (High, Medium, Low) for monitoring virtual machine heartbeats. • Advanced Options - Click Advanced Options to set advanced configuration options for HA.

Adding an Inventory Object : Editing a Cluster : Customizing HA for Virtual Machines

Customizing HA for Virtual Machines You can customize HA for VM restart priority and Host isolation response: • VM restart priority determines the order in which virtual machines are restarted when the host fails. The restart priority is always considered, but is especially important in the following cases: • If you’ve set host failure to a certain number of hosts (for example, three) and more hosts fail (for example, four) • If you’ve turned off strict admission control and started more virtual machines than HA was set up to support • Host isolation response determines what happens when a host in an HA cluster loses its console network connection but continues running. By default, virtual machines are left powered on in case of a host isolation incident. You can change this behavior for individual virtual machines. Disk locking usually prevents two instances of a virtual machine from running on two different hosts, but a problem might occur if you’re using NAS or iSCSI storage. In that case, VMware recommends that you keep the Host isolation response at Power off VM. To customize HA behavior for individual virtual machines 1.

Select the cluster, click the Edit Settings link, and select Virtual Machine Options under VMware HA.

2.

For each virtual machine, select from the VM restart priority pop-up menu to customize its settings.

3.

For each virtual machine, you can select from the Host isolation response pop-up menu to customize its settings. See Configuring HA Settings for a list of these settings. In addition to these settings, when customizing behavior for an individual virtual machine, you can also select Use cluster setting – The virtual machine should use the default behavior configured for the cluster on the VMware HA page.

If you add a host to a cluster, all virtual machines in the cluster default to a VM restart priority of Medium and an Host isolation response of Leave VM powered on. [email protected] | Copyright © 2008 VMware, Inc. All rights reserved.

Adding an Inventory Object : Editing a Cluster : Using DRS Rules

Using DRS Rules After you create a DRS cluster, you can edit its properties to create rules that specify affinity. You can use these rules to determine that: • DRS try to keep certain virtual machines together on the same host (for example, for performance reasons). • DRS try to keep certain virtual machines apart (for example, for high availability). You might want to guarantee that certain virtual machines are always on different physical hosts. When a problem occurs with one host, you don’t lose both virtual machines. To create a DRS rule 1.

Select the cluster and click the Edit Settings link.

2.

In the Cluster Settings dialog box, choose Rules.

3.

In the Virtual Machine Rule dialog box, name the rule so that you can later find and edit it.

4.

Choose an option from the pop-up.

5.

Click Add to add virtual machines and click OK when you’re done.

After you’ve added the rule, you can edit it, look for conflicting rules, or delete it. To edit an existing rule 1.

Make changes in the dialog box and click OK when you’re done.

If you have two conflicting rules, you cannot enable both. For example, if one rule keeps two virtual machines together and another rule keeps the same two virtual machines apart, you cannot enable both rules.

Understanding Rule Results When you add or edit a rule, and the cluster violates immediately of that rule, the system continues to operate and tries to correct the violation. For manual and partially automated DRS clusters, migration recommendations are based on rule fulfillment and load balancing. You are not required to fulfill the rules, but the corresponding recommendations remain until the rules are fulfilled.

Disabling or Deleting Rules You can disable a rule or remove it completely. To disable a rule 1.

Select the cluster and click the Edit Settings link.

consumption of ESX hosts in the cluster. DPM monitors the resource use of the running virtual machines in the cluster. If sufficient excess capacity exists, DPM recommends moving virtual machines to other hosts in the cluster and placing the original host into standby mode to conserve power. If insufficient capacity exists, DPM might recommend returning standby hosts to a fully powered-on state. You can configure power management to operate in either Manual or Automatic mode. In Manual mode, VirtualCenter makes power management recommendations, but does not migrate virtual machines or move hosts into or out of standby mode. In Automatic mode, VirtualCenter migrates virtual machines and moves hosts into or out of standby mode automatically. These settings can be overriden on a per-host basis. Note: DRS automation settings do not affect power management automation settings. 1.

Adding an Inventory Object : Editing a Cluster : Configuring VMware EVC Settings

Configuring VMware EVC Settings You can use the VMware Enhanced VMotion Compatibility (EVC) feature to help ensure VMotion compatibility for the hosts in a cluster. EVC ensures that all hosts in a cluster present the same CPU feature set to virtual machines, even if the actual CPUs on the hosts differ. This prevents migrations with VMotion from failing due to incompatibile CPUs. EVC cannot prevent virtual machines from accessing hidden CPU features in all circumstances. Applications that do not follow CPU vendor recommended methods of feature detection may behave unexpectedly in an EVC environment. VMware EVC cannot be supported with ill-behaved applications that do not follow the CPU vendor recommendations.. Before you enable EVC for a cluster, do the following: 1.

Ensure that all hosts in the cluster either have CPUs with live migration support (Intel FlexMigration or AMD Extended Migration) or have the CPU whose baseline feature set you intend to enable for the cluster.

2.

Ensure that all the hosts in the cluster have CPUs from the same vendor.

3.

Power off or evacuate all virtual machines in the cluster.

To configure EVC 1.

Right-click the cluster and choose Edit Settings.

2.

In the left panel, select VMware EVC.

3.

Select one of the following options: • Disable EVC – The EVC feature is disabled. CPU compatibility is not enforced for the hosts in this cluster. • Enable EVC for Intel® Hosts – The EVC feature is enabled. All hosts in this cluster present the baseline feature set of Intel Core™ 2 Xeon® processors to virtual machines. This option is unavailable if AMD hosts are present in the cluster, or if EVC cannot be enabled. • Enable EVC for AMD Hosts – The EVC feature is enabled. All hosts in this cluster present the baseline feature set of Second Generation AMD Opteron™ processors to

virtual machines. This option is unavailable if Intel hosts are present in the cluster, or if EVC cannot be enabled. If EVC cannot be enabled, the Details pane displays the reason or reasons why. If EVC cannot be enabled due to incompatible hosts, the Incompatible Hosts pane lists these hosts along with the reason for the incompatibility. 4.

To view the CPUID feature flags currently enforced by EVC, click Current CPUID Details. The Current CPUID Details dialog box displays the CPUID feature flags that EVC is enforcing for the hosts in this cluster. For more information on CPUID feature flags, see Intel Processor Identification and the CPUID Instruction (available from Intel), or CPUID Specification (available from AMD).

Adding an Inventory Object : Editing a Cluster : Configuring a Virtual Machine Swapfile Location for a Cluster

Configuring a Virtual Machine Swapfile Location for a Cluster By default, swapfiles for a virtual machine are located on a VMFS3 datastore in the folder that contains the other virtual machine files. However, you can instead configure the hosts in your cluster to place virtual machine swapfiles on an alternative datastore of your choice. You might use this option to place virtual machine swapfiles on either lower-cost or higherperformance storage, depending on your needs. Note: Setting an alternative swapfile location might cause migrations with VMotion to complete more slowly. For best VMotion performance, store virtual machine swapfiles in the same directory as the virtual machine. To configure a virtual machine swapfile location for a cluster 1. 2.

Configure the virtual machine swapfile locations for the hosts in the cluster as described in Configuring Virtual Machine Swapfile Properties for the Host. Select the cluster, click the Edit Settings link, and select VM swapfile location. • Select Store the swapfile in the same directory as the virtual machine to store the swapfile in the same directory as the virtual machine configuration file. • Select Store the swapfile in the datastore specified by the host to store the swapfile in the location specified in the host configuration. If you cannot store the swapfile in the datastore that the host specifies, the swapfile is stored in the same folder as the virtual machine.

Adding an Inventory Object : Adding or Editing a Resource Pool

Adding or Editing a Resource Pool After you create a datacenter and added a clustered or standalone host to your VirtualCenter Server, you can create a resource pool. Resource pools allow you to delegate control of host resources, but the benefits are especially evident when resource pools are used to compartmentalize all resources in a cluster. You can create multiple resource pools as direct children of the host or cluster and configure them,

file://D:\Documents and Settings\Administrator\Local Settings\Temp\~hh3F5A.htm

and delegate their control to other individuals or organizations. See the Resource Management Guide topic “Why Use Resource Pools?” (Choose Help > Manuals.) You can create a child resource pool of any host, resource pool, or DRS cluster. When you create a child resource pool, you are prompted for resource pool attribute information.

For each NIC, use the Network drop-down menu to select one of the port groups that are configured for virtual machine use on the host. If no virtual machine port groups are configured, a warning appears, and you cannot configure any virtual network cards. For information about port groups, see Adding a Virtual Switch.

3.

For each NIC, select the adapter type. Depending on the host version and the guest operating system, a choice of adapter types for each virtual NIC might not be available. In many cases, only one type of adapter is supported. If more than one type of adapter is supported, the recommended type for the guest operating system is selected by default. The following adapter types might be available: • Vlance – Supported only on legacy virtual machines. A Vlance adapter uses the stock driver that the guest operating system provides, and does not require that VMware Tools be installed on the virtual machine. However, it provides relatively poor performance. • Vmxnet – Supported only on legacy virtual machines. It usually provides significantly better performance than a Vlance adapter, but it requires that VMware Tools be installed on the virtual machine. • Flexible – Supported on virtual machines created on ESX Server 3.0 or later and that run 32-bit guest operating systems. The Flexible adapter functions as a Vlance adapter if VMware Tools is not installed in the virtual machine, and as a Vmxnet driver if VMware Tools is installed in the virtual machine. • E1000 – A virtual adapter that emulates an E1000 network card. It is the default adapter type for virtual machines created on ESX Server 3.0 or later and that run 64bit guest operating systems. • Enhanced Vmxnet – An upgraded version of the Vmxnet driver with enhanced performance. It requires that VMware Tools be installed on the virtual machine.

Adding an Inventory Object : Creating a Virtual Machine : Selecting and Configuring a LUN

Selecting and Configuring a LUN This page enables you to select the LUN to store the virtual machine’s data in. Selecting a specific LUN is useful if you are running applications on the virtual machine that need to be aware of the physical characteristics of the storage device. This page is part of the Custom configuration and appears when you store virtual machine data on a LUN. When you map a LUN to a VMFS volume, VI Client creates a mapping file that points to the raw LUN. Encapsulating disk information in a file allows VI Client to lock the LUN so that only one virtual machine can write to it. This mapping file has a .vmdk extension, but the file contains only disk information describing the mapping to the LUN on the ESX Server system; the actual data is stored on the LUN. Using the VI Client, you cannot deploy a virtual machine from a template and store its data on a LUN.
