  • Is there an upper limit on the routing information that can be set for the subnet on the logical network?ECL2.0, Logical Network

    There is a limit when setting with the GUI (up to 4 lines).
    If you try to set more than 5 lines, the creation/editing of the subnet fails due to an error. (Error message: "Maximum length of static route exceeded")
    Reference: Tutorial - Logical Network -  Subnet Details

    On the other hand, there is no upper limit when setting with API.

    To set routing information of 5 lines or more, please execute it with API.

  • Please tell me the behavior when pushing the "ctrl+alt+delete" button in console screen of virtual server.ECL2.0, Virtual Server

    The behavior is different depending on the OS.

    【Linux】
    If the guest OS is Linux, when you push the ctrl+alt+delete button, your virtual server will be rebooted.
    With the following command, you can disable the reboot function of the ctrl+alt+delete button.
    ------------------------------------------
    # systemctl mask ctrl-alt-del.target
    ------------------------------------------

    ※Even if you disabled the reboot function following the above methods if you click the ctrl+alt+delete button 7 times in 2 seconds (= sending the SIGNAL 7 times in 2 seconds), your virtual server will be rebooted.
    Please see the SIGNAL entries in the manual page of systemd (the URL shown below) for more information.
    -------
    https://man7.org/linux/man-pages/man1/systemd.1.html#SIGNALS
    -------

    【Windows】
    If the guest OS is Windows OS, if you click the ctrl+alt+delete button, your virtual server will not be rebooted.
    Instead of the OS reboot, the security option screen is displayed like the following image.

  • I tried to put QCOW2 format private template in the volume but the status became an error and I could not configure it as bootable and couldn't create the root volume.ECL2.0, Virtual Server

    It's considered that the prepared volume size was insufficient in its size against the QCOW2 format private template.
    Regarding how to deal with the error, please create a bigger volume than the prepared volume size and put the QCOW2 format image template in the newly created bigger volume again.
    After that, please confirm whether the status should become an error again.

    Example)
    [issue] I tried to put QCOW2 format "Windows Server 2012 R2 Standard Edition" private template(13.6GB) into the 15GB volume and the status became an error.
    [cause] It's considered that the volume size was insufficient against the private template image created with "Windows Server 2012 R2 Standard Edition". When you create the volume with "Windows Server 2012 R2 Standard Edition", the volume size must be over 80GB. (see below document)
    [workaround] I created the volume over 80GB and put the image template in it again and I was able to create the root volume without problems.

    If you changed the volume size (= created the bigger volume) but the status should become an error repeatedly, we are sorry to bother you but we would like you to create a ticket to bring the issue to our attention.

    ** Reference URL **
    [Service Descriptions: Restrictions on the official image] Each OS has the minimum necessary volume size.
    Service Descriptions - Virtual server - Restrictions on the official image

    ※Excerpt from the above Restrictions
    When you create a volume with the official image template, you are unable to create the volume if the size is less than the official image template size.
    (example: If you need to use Windows OS, you will need to prepare 80GB volume or bigger volume.)

    [FAQ: Difference between RAW format and QCOW2 format] ※If QCOW2 format, the data is compressed and uploaded to Image Storage.
    FAQ - If I upload my private template image to "Image Storage", which format should I select, RAW or QCOW2?Please tell me the difference between the two formats as well.
  • If I upload my private template image to "Image Storage", which format should I select, RAW or QCOW2? Please tell me the difference between the two formats as well.ECL2.0, Image Storage

    When you create the template image in RAW format, the data is not compressed and the image is uploaded to "Image Storage".
    If you create the template image in QCOW2 format, the data is compressed and the image is uploaded to "Image Storage".
    QCOW2 format tends to take less time than RAW format when it is uploaded to "Image Storage".
    However, when you create the image in QCOW2 format, it sometimes takes long time to compress the data.

  • Is it possible to separate the billing destination of the usage fee for each tenant?Billing, ECL2.0

    It's not possible to separate the billing for each tenant since the usage fee is tied with the contract ID.
    You need to have multiple contracts of Enterprise Cloud 2.0 to separate the billing of usage fee.

  • I can't move the mouse pointer (mouse cursor) on the console screen accessed via the Cloud Computing Control Panel. (Mouse cursor is stuck on screen, and won't move.)ECL2.0, Virtual Server

    If you can't move the mouse pointer on the console screen, please try the following countermeasures.

    (1) "Changing the browser" or "Changing the client PC"
    You may be able to move the mouse pointer (mouse cursor).

    (2) Restart the virtual server.
    If there is no change after trying (1), please restart the virtual server via the Cloud Computing Control Panel at your discretion.

    Enterprise Cloud 2.0 has adopted Openstack as the cloud platform and the mechanism of the console connection to the virtual server also follows the mechanism of Openstack.
    Compared to the physical serial console connection, the console connection of the Openstack is less stable.

    Therefore, we strongly recommend the customer to enable the remote connection such as SSH or RDP connection as an alternative of the console connection to access to the virtual server resources.

  • Is there any influence such as disconnection of the network when changing SSL protocol in SSL Parameter setting of LoadBalancer?ECL2.0, Load Balancer

    There is no influence on network connection except for the SSL communication which is targeted as the change of SSL protocol.

  • When I tried to create a volume, "Error writing field to database (HTTP 400)" was shown and I could not create the volume.ECL2.0, Virtual Server
    As specification, if "Emoji" or "variant characters" are entered in the description field when you create a volume, it will result in the following error "Error writing field to database (HTTP 400)".
    Please retry to create a volume without using "Emoji" or "variant characters" in the description field.
    "Variant characters" are the old characters that have the same pronunciation and meaning but different form and shape.
  • I don't know how to create the organizational virtual data center network in "Managed v Platform Powered by VMware - vCloud Director Tenant Portal"ECL2.0, Managed v Platform Powered by VMware

    - In JP4 region only

    The organizational virtual data center network is the logical switch (Layer 2 network) functioning in the organizational virtual data center provided as the menu of "Managed v Platform Powered by VMware".
    You can connect the organizational virtual data center network to the interface of the edge (edge service gateway / distributed logical router) or the NIC of Virtual Machine(s).
    You can create a network like the following diagram by using the organizational virtual data center network.

    • Name
    • Gateway CIDR
      • You need to input the IP address which you assign to the interface of the Edge Service Gateway in which only DHCP service is enabled.
      • When you connect the NIC of Virtual Machine to the organizational virtual data center network, if you select IP mode : Static - IP Pool or Static - Manual, the guest OS running on the Virtual Machine configures this value as the default gateway IP address, in the process of the first boot after the NIC of the Virtual Machine was connected to the organizational virtual data center network.
      • When you connect the NIC of Virtual Machine to the organizational virtual data center network, if you select IP mode as DHCP and DHCP is enabled in the guest OS running on the Virtual Machine, the guest OS gets an IP address from the Edge Gateway Service in which only DHCP service is enabled and the guest OS configures the IP address as the IP address of the default gateway.
    • Shared Network
