When you create an instant-clone desktop pool, the Add Desktop Pool wizard prompts you to configure certain options. You can use this worksheet to record your configuration options before you create the pool.

Before creating an instant-clone desktop pool, take a snapshot of the parent VM. You must shut down the parent VM before taking the snapshot. The snapshot is the base image for the clones.
Note: You cannot create an instant-clone desktop pool from a VM template.
Table 1. Worksheet: Configuration Options for Creating an Instant-Clone Desktop Pool
Option Description Fill In Your Value Here
User assignment Select Floating. Users are assigned random desktops from the pool.
vCenter Server Select Instant clones and select the vCenter Server that manages the instant-clone VMs.
Desktop Pool ID The unique name that identifies the pool in View Administrator.

If you have multiple Connection Server configurations, make sure that another Connection Server configuration does not use the same pool ID. A Connection Server configuration can consist of a single Connection Server or multiple Connection Servers

Display name The pool name that users see when they log in from a client. If you do not specify a name, the pool ID is used.
Access group Select an access group for the pool, or leave the pool in the default root access group.

If you use an access group, you can delegate managing the pool to an administrator who has a specific role. For details, see the role-based delegated administration chapter in the View Administration document.

Note: Access groups are different from vCenter Server folders that store desktop VMs. You select a vCenter Server folder later in the wizard.
State If set to Enabled, the pool is ready for use after provisioning. If set to Disabled, the pool is not available to users. During provisioning, if you disable the pool, provisioning stops.
Connection Server restrictions You can restrict access to the pool to certain Connection Servers by clicking Browse and selecting one or more Connection Servers.

If you intend to provide access to desktops through VMware Identity Manager, and you configure Connection Server restrictions, the VMware Identity Manager app might display desktops to users when those desktops are actually restricted. VMware Identity Manager users will be unable to launch these desktops.

Automatically logoff after disconnect
  • Immediately. Users are logged off when they disconnect.
  • Never. Users are never logged off.
  • After. The time after which users are logged off when they disconnect. Type the duration in minutes.

    The logoff time applies to future disconnections. If a desktop session is already disconnected when you set a logoff time, the logoff duration for that user starts when you set the logoff time, not when the session was originally disconnected. For example, if you set this value to 5 minutes, and a session was disconnected 10 minutes earlier, View will log off that session 5 minutes after you set the value.

Allow user to initiate separate sessions from different client devices With this option selected, a user connecting to the same desktop pool from different client devices gets different desktop sessions. The user can only reconnect to an existing session from the same client device. When this setting is not selected, users are always reconnected to their existing session no matter which client device is used.
Default display protocol Select the default display protocol. The choices are Microsoft RDP, PCoIP, and VMware Blast.
Allow users to choose protocol Specify whether users can choose display protocols other than the default.
HTML Access Select Enabled to allow users to connect to remote desktops from a Web browser. For more information about this feature, see Using HTML Access, available from https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.

To use HTML Access with VMware Identity Manager, you must pair Connection Server with a SAML authentication server, as described in the View Administration document. VMware Identity Manager must be installed and configured for use with Connection Server.

Adobe Flash quality Select the quality of Adobe Flash content on Web pages.
  • Do not control. The Web page settings determine the quality.
  • Low. This setting consumes the least amount of bandwidth. If no quality level is specified, this is the default level.
  • Medium. This setting consumes a moderate amount of bandwidth.
  • High. This setting consumes the most amount of bandwidth.

For more information, see Adobe Flash Quality and Throttling.

Adobe Flash throttling Select the frame rate of Adobe Flash movies. If you enable this setting, you can reduce or increase the number of frames displayed per second by selecting the throttling level.
  • Disabled. No throttling is performed.
  • Conservative. Timer interval is 100 milliseconds. This setting results in the lowest number of dropped frames.
  • Moderate. Timer interval is 500 milliseconds.
  • Aggressive. Timer interval is 2500 milliseconds. This setting results in the highest number of dropped frames.

For more information, see Adobe Flash Quality and Throttling.

Stop provisioning on error Specify whether View stops provisioning desktop VMs if an error occurs and prevents the error from affecting multiple VMs.
Naming pattern Specify a pattern that View uses as a prefix in all the desktop VM names, followed by a unique number.

For more information, see Using a Naming Pattern for Automated Desktop Pools.

Max number of machines Specify the total number of desktop VMs in the pool.
Number of spare (powered on) machines Specify the number of desktop VMs to keep available to users. For details, see Naming Machines Manually or Providing a Naming Pattern.

Provision machines on demand

Min number of machines

Provision all machines up front

Specify whether to provision all desktop VMs when the pool is created or to provision the VMs when they are needed.
  • Provision all machines up front. When the pool is created, View provisions the number of VMs you specify in Max number of machines.
  • Provision machines on demand. When the pool is created, View creates the number of VMs based on the Min number of machines value or the Number of spare (powered on) machines value, whichever is higher. Additional VMs are created to maintain this minimum number of available VMs as users connect to desktops.
Select separate datastores for replica and OS disks Specify whether to store the replica and OS disks on a datastore that is different from the datastores that the instant clones are on.

For more information, see Storing Replicas and Clones on Separate Datastores for Instant Clones and View Composer Linked Clones.

Parent VM Select the parent VM for the pool.
Snapshot (default image) Select the snapshot of the parent VM to use as the base image for the pool.
VM folder location Select the folder in vCenter Server for the desktop VMs.
Cluster Select the vCenter Server cluster for the desktop VMs.
Resource pool Select the vCenter Server resource pool for the desktop VMs.
Datastores Select one or more datastores for the desktop VMs.

The Select Instant Clone Datastores window provides high-level guidelines for estimating the pool's storage requirements. These guidelines help you determine which datastores are large enough to store the clones. The Storage Overcommit value is always set to Unbounded and is not configurable.

Domain Select an Active Directory domain. The drop-down list shows the domains that you specify when you configure instant-clone domain administrators. See Add an Instant-Clone Domain Administrator
AD container Specify the Active Directory container's relative distinguished name.

For example: CN=Computers

In the Add Desktop Pool window, you can browse the Active Directory tree for the container.

Power-off script Specify the path name of a script to run on the desktop VMs and the script parameters before the VMs are powered off.
Post-synchronization script Specify the path name of a script to run on the desktop VMs and the script parameters after the VMs are created.
