Creating/Deleting a Virtual Server

You can select the virtual server you want to create from several types, according to the purpose (such as to serve as a web server or as an application server). You can also delete servers that are in use at any time if they are no longer needed.

Creating a Virtual Server

You can create a virtual server from one of the image types explained below.

When you create a virtual server, specify the following:

Important: In order to use the functions available when you create a virtual server, a virtual router must be connected to the network to which the virtual server connects.
Tip:

For Red Hat Enterprise Linux and CentOS, the default host name for virtual servers is configured as the following:

<Virtual_server_name_entered_when_creating_the_virtual_server>.fcxlocal

Administrator Password for a Virtual Server

  • For Windows

    When you create the virtual server, specify the key pair name that you have created as a parameter. Use key file (*.pem) of the specified key pair to acquire the random Administrator password that is issued by the system.

    Example: How to decrypt the random password that was issued

    $ COMPUTE=endpoint of virtual server API 
$ OS_AUTH_TOKEN=token string acquired 
$ SERVER_ID=ID of created Windows virtual server 
$ PROJECT_ID=project ID of created Windows virtual server 
$ curl -s $COMPUTE/v2/$PROJECT_ID/servers/$SERVER_ID/os-server-password -X GET -H "X-Auth-Token: $OS_AUTH_TOKEN" | jq . 
{ 
  "password": "password string" 
} 
$ PASSWORD=password string acquired by above command 
$ echo $PASSWORD | openssl base64 -d -A | openssl rsautl -decrypt -inkey key file(.pem)
    Note: After you have created the virtual server, confirm that it is in an ACTIVE state, and then acquire the password string.

Deleting a Virtual Server

If you no longer need a certain virtual server, you can delete it at any time.

Note: You can delete a virtual server even while it is running. Therefore, extra caution must be exercised when you delete one.
Note: While data obtained using a snapshot remains, it is not possible to delete the virtual server that is the source of the snapshot. To delete the virtual server, it is necessary to delete all obtained snapshots first.
Tip:
  • When you create a virtual server, specify whether to retain the system storage of the server upon deletion.
  • If you specify to retain the system storage, we recommend that you stop the server in advance in order to avoid damage to the data in the system storage.

Virtual Server Type (Flavor)

There are two types of virtual server CPU: standard CPU and high-speed CPU.

Type Overview
Standard CPU Virtual CPU speed equivalent to 1.7 - 1.8 GHz
High-Speed CPU Virtual CPU speed equivalent to 2.6 GHz

The types (flavors) of virtual servers that are provided are as follows:

Automatic Failover

If the server stops during an operation due to issues such as failure of the physical host machine at the data center, you can automatically move the virtual server that was operating on that host machine to a different host machine and operate the server there. When you create a virtual server, specify whether to enable an automatic failover.

Important: You cannot select virtual machines for which you enabled an automatic failover as targets of auto-scaling.
Note: When automatic failover occurs or is completed, a notification email is sent to the overall administrator of the project the target resource belongs to. For details on notification emails, refer to Automatic Failover Notification Messages.
