Virtual Server - FAQ
- Is it possible to remove image which was created with protection turned "on"?ECL2.0, Virtual Server
For images created by turned on protection in the GUI, it is necessary to remove the protection once before removing.
For steps to remove protection, refer to the following API references,
and modify setting to "protected:false". - License activation fails on the virtual server created from Windows Server Official Image Template.ECL2.0, OS, Virtual Server
There is a possibility that connectivity to the license server provided by NTT Com may not be established.
Follow the steps below to ensure connectivity to the license server.Tutorial - Activate your OS License
Reference：Service Descriptions - Windows Server - Conditions for Usage with Other Services
In order to implement OS license authentication, a common function gateway is required. When using Windows Server, please make sure to apply common function gateway.
Also, if the common function gateway is removed, OS license authentication will be lost. Therefore, please be careful not to remove the common function gateway from the Windows Server that you are using. - It is not possible to detach root volume from instance.ECL2.0, Virtual Server
Root volume is not able to detach unlike data volume. Root volume continue to be root volume for appropriate instance unless deleting instance.
Reference：Service Descriptions - Glossaries of Volume - Why did the content of the resource status display change?Common, ECL2.0, Virtual Server
The following cases are possible.
An alert was detected in the monitoring resource on the physical server that houses the customer resource.
Therefore, we judged that there was a possibility that the entire resource on the corresponding physical server was affected, including customer resources, and posted information on the resource status.
However, in fact, it was a matter of individual monitoring resources, it turned out that customer resources were not affected, so customer notification was not implemented.
After that, our company restored the monitoring resource by restarting the monitoring resource, so it may not be shown in the resource status.
- The IP address of the NIC has been changed on the virtual server, but the IP address displayed in the instance summary is not updated.ECL2.0, Virtual Server
When changing the IP address of the virtual server, it is necessary not only to change the IP on the guest OS (Windows or Linux) but also to operate on the Enterprise Cloud 2.0 portal.
Specifically, it is necessary to newly connect the interface and delete the unnecessary interface for the IP address for replacement.
Please refer to the following for working method.
Tutorial - Virtual Server - Add a Network Interface to the Instance
Please refer to below FAQ.
When restarting right after configuring the interface or volume, encounter that the volume goes offline or the device name of the interface has been changed - There is no alert on the resource status display function, why did the alert mail notification came?Common, ECL2.0, Virtual Server
- Error in resource status display function.Is there a problem?Common, ECL2.0, Virtual Server
An alert was detected in the monitoring virtual server instance installed on the same physical server that houses the customer virtual server instance.
Therefore, if there is a possibility that the entire virtual server instance on the same physical server may be affected, the operation status of the monitoring virtual server instance is displayed on the resource status screen.
However, due to the failure of the monitoring virtual server instance alone, if the customer virtual server instance is operating normally, there will be no separate notification via e-mail.
When a failure of the monitoring virtual server instance is recovered, the status indicating abnormality will not be displayed.
- Error in resource status display function. There is no error indication now, but I want to know if there is any influence.Common, ECL2.0, Virtual Server
An alert was detected in the monitoring virtual server instance installed on the same physical server that houses the customer virtual server instance.
Therefore, if there is a possibility that the entire virtual server instance on the same physical server may be affected, the operation status of the monitoring virtual server instance is displayed on the resource status screen.
However, if there is a failure of the monitoring virtual server instance alone and the customer virtual server instance is operating normally, there will be no separate notification via e-mail.
When a failure of the monitoring virtual server instance is recovered, the status indicating abnormality will not be displayed.
- How do I specify the order of NICs when creating virtual server instances?ECL2.0, Virtual Server
At the time of instance creation, when there are multiple logical networks connected and configured, NICs will be randomly recognized from multiple logical networks when the instance starts up.
If you want to specify the order of NICs arbitrarily, please try the following procedure.
===============================
1. When creating a virtual server, create it by connecting only one logical network
2. Stop virtual server
3. Connect another logical network to the virtual server
4. Activate the virtual server and check whether the order of NICs is in the intended state
5. Repeat the above 2,3,4 as many times as the number of logical networks you want to connect
=============================== - I can not create a virtual server using a specific IP address in the IP address band of the logical network. There is a response of ping even though I am not using the corresponding IP address.ECL2.0, Virtual Server
When creating a subnet for a logical network, if you check [Enable DHCP], it will use one IP address for the DHCP server (the lowest number of unused addresses in the IP address assignment pool will be automatically assigned). Also, this DHCP server returns a ping response.
Please use other than the IP address assigned for the DHCP server.* (Supplement) What is DHCP (server address setting function) of the logical network?
