Operations on a Virtual Server

You can carry out the following operations on a virtual server that has been created in the system.

Startup/Termination of a Virtual Server

Start the created virtual server from a shut-down state (SHUTOFF). Or, shut down the server from an operating state (ACTIVE).

Important: A virtual server that is shut down from the OS or terminated from the service portal/API will be subject to usage charges. After termination, servers that are used infrequently can be released in order to reduce costs.
Note: A virtual server that is terminated from the service portal/API will be stopped forcibly, which is equivalent to a forced power shutdown. To shut down a virtual server normally, log in to the virtual server and carry out a shutdown operation.

Release/Restoration of a Virtual Server

In order to release the CPU and memory resources in use by the virtual server, release the virtual server. Virtual servers that have been released will enter a released state (SHELVED_OFFLOADED).

Tip: You can release a virtual server, regardless of whether it is in a running state or in a terminated state.
Note:

You cannot carry out the following operations on a virtual server that has been released:

  • Connection/disconnection of port
  • Attachment/detachment of a block storage
  • Changing of virtual server type
  • Re-creation of virtual server
  • Startup/termination of virtual server

In order to return a released server to a state in which it can be used normally, restore the virtual server.

Important: When you restore a virtual server, it is restored to an operating (ACTIVE) state. Be aware that charges are applied for services such as the OS provision service and the software provision service.

Rebooting a Virtual Server

  • Soft reboot (equivalent to the OS reboot command)
  • Hard reboot (equivalent to the reset button)

Changing Virtual Server Settings

You can change the existing settings of a virtual server. You can make the following changes:

  • Change of the virtual server name
  • Change of the IP address
Note:
  • Even if a virtual server's name is changed, the computer name on the OS is not changed. To change the computer name (host name), change it from on the OS.
  • For IP addresses, only IPv4 addresses can be changed.

Attachment/Detachment of a Block Storage

Specify the device name of the existing block storage (example: /dev/vdb) and attach it. You can also detach a block storage that is no longer needed.

Port Connection/Disconnection

Ports can be added or removed on the virtual server.
