Descriptions of Server/Group Power Commands

Updated by Richard Seroter on Jun 10, 2015


CenturyLink Cloud users can issue power commands against individual servers or Groups of servers. For Groups, this makes it easy to quickly power off or reboot entire sets of servers with a single command. This KB article explains what each power command does to the underlying virtual machine.

Data Center Menu



Applies to cloud servers that are powered off. Initiates the operating system boot sequence. Billing charges for memory, CPU, and licenses (if applicable) start accruing, and monitors are re-enabled.

Shut Down

Initiates a graceful shutdown of the corresponding server or servers. Like the "off" power command, all memory and CPU charges cease, monitors are disabled, and the machine is left in a powered off state.


When a virtual machine is paused, its state is frozen (e.g. memory, open applications) and monitoring ceases. Billing charges for CPU and memory stop. A paused machine can be quickly brought back to life by issuing the "On" power command. Any applicable licensing charges continue to accrue while a machine is paused.


Executes a graceful reboot of the target server or servers. Unlike the forced "reset" power command, this instructs the operating system to initiate a proper stop and restart.

Power Off

This is a forced shutdown of a server. It's the equivalent to unplugging a physical machine. All memory and CPU charges stop accruing, monitors are disabled, and the machine ends up in a powered off state. Any licensing charges (if applicable) and storage charges continue accruing. If the server is moved to archive storage, then any applicable licensing charges cease.


Similar to the relationship between "Off" and "Shut Down", the reset command is a forced power off + power on combination. It is equivalent to the reset button on a physical computer.
