Description: Sets the value of an environment variable in a guest OS. On a Windows Series guest, writing these values is saved persistently so they are immediately visible to every process. On a Linux or Windows 9X guest, writing these values is not persistent so they are only visible to the VMware tools process.

NOTE: All functions that execute in a guest operating system require VMware Tools to be installed and running. Additionally, a valid guest login is required to run this activity.

Description

Connection

 

 

 

 

Indicates where connection details, guest credentials and other preferences should originate from. This is a visual mode parameter used only during task construction and configuration, thus, comprises no markup. The available options are:

  • Host (Default) - Connection details, guest credentials and other preferences are configured individually for this activity. Select this option if only a single activity is required to complete an operation.

  • Session - Connection details, guest credentials and other preferences are obtained from a session created in a previous step with the use of the WMware Guest - Connect activity. Select this option if a combination of activities within the same action group are required to complete an operation. Linking several activities to a single session eliminates redundancy and improves efficiency. Several sessions can exist in a single task. Multiple sessions can run simultaneously without interference.
