Do not turn on SSL for provisioning or downloading local mode desktops.

If the performance of View Connection Server is affected by the number of local desktops, set the heartbeat
n
interval to be less frequent. The heartbeat lets View Connection Server know that the local desktop has a
network connection. The default interval is five minutes.
Pools for Kiosk Users
Kiosk users might include customers at airline check-in stations, students in classrooms or libraries, medical
personnel at medical data entry workstations, or customers at self-service points. Accounts associated with
client devices rather than users are entitled to use these desktop pools because users do not need to log in to
use the client device or the View desktop. Users can still be required to provide authentication credentials for
some applications.
View desktops that are set to run in kiosk mode use stateless desktop images because user data does not need
to be preserved in the operating system disk. Kiosk mode desktops are used with thin client devices or locked-
down PCs. You must ensure that the desktop application implements authentication mechanisms for secure
transactions, that the physical network is secure against tampering and snooping, and that all devices
connected to the network are trusted.
As a best practice, use dedicated View Connection Server instances to handle clients in kiosk mode, and create
dedicated organizational units and groups in Active Directory for the accounts of these clients. This practice
not only partitions these systems against unwarranted intrusion, but also makes it easier to configure and
administer the clients.
To set up kiosk mode, you must use the
documented in the topics about kiosk mode in the VMware View Administrator's Guide. As part of this setup,
you can use the following pool settings.
Create an automated pool so that desktops can be created when the pool is created or can be generated
n
on demand based on pool usage.
Use floating assignment so that users can access any available desktop in the pool.
n
Create View Composer linked-clone desktops so that desktops share the same base image and use less
n
storage space in the datacenter than full virtual machines.
Institute a refresh policy so that the desktop is refreshed frequently, such as at every user logoff.
n
Use an Active Directory GPO (group policy object) to configure location-based printing, so that the desktop
n
uses the nearest printer. For a complete list and description of the settings available through Group Policy
administrative (ADM) templates, see the VMware View Administrator's Guide.
Use a GPO if you want to override the default policy that enables connecting local USB devices to the
n
desktop when the desktop is launched or when USB devices are plugged in to the client computer.
Desktop Virtual Machine Configuration
Because the amount of RAM, CPU, and disk space that virtual desktops require depend on the guest operating
system, separate configuration examples are provided for Windows XP, Windows Vista, and Windows 7
virtual desktops.
The example settings for virtual machines such as memory, number of virtual processors, and disk space are
VMware View-specific.
