216 Deploying Your Operating System Using VMCLI
The latter technique is useful in script programs, as it allows the script
to proceed after a new process is started for the VMCLI command (otherwise,
the script would block until the VMCLI program is terminated).
When multiple VMCLI instances are started in this way, and one or more of
the command instances must be manually terminated, use the operating
system-specific facilities for listing and terminating processes.
VMCLI Return Codes
English-only text messages are issued to standard error output whenever
errors are encountered.
