Remote desktop power policy
When this desktop pool is provisioned, three desktops are created and powered on. If the desktops are powered
off in vCenter Server, they are immediately powered on again, according to the power policy.
After a user connects to a desktop in the pool, the desktop becomes permanently assigned to that user. After
the user disconnects from the desktop, the desktop is no longer available to any other user. However, the
Ensure desktops are always powered on policy still applies. If the assigned desktop is powered off in vCenter
Server, it is immediately powered on again.
When another user connects, a second desktop is assigned. Because the number of spare desktops falls below
the limit when the second user connects, another desktop is created and powered on. An additional desktop
is created and powered on each time a new user is assigned until the maximum desktop limit is reached.
Preventing View Power Policy Conflicts
When you use View Administrator to configure a power policy, you must compare the power policy to the
settings in the guest operating system's Power Options control panel to prevent power policy conflicts.
A View desktop can become temporarily inaccessible if the power policy configured for the virtual machine
desktop is not compatible with a power option configured for the guest operating system. If there are other
desktops in the same pool, they can also be affected.
The following configuration is an example of a power policy conflict:
In View Administrator, the power policy Suspend is configured for the virtual machine desktop. This
n
policy causes the virtual machine to enter a suspended state when it is not in use.
In the Power Options control panel in the guest operating system, the option Put the Computer to sleep
n
is set to three minutes.
In this configuration, both View Connection Server and the guest operating system can suspend the virtual
machine. The guest operating system power option might cause the virtual machine to be unavailable when
View Connection Server expects it to be powered on.
I The default power plan on Windows 7 systems causes View desktops to become temporarily
MPORTANT
inaccessible when the operating system enters sleep mode. To prevent Windows 7 systems from entering sleep
mode, change the power plan setting Put the computer to sleep to Never.
