Installing UltraVR Using a Template

This section describes how to install UltraVR by importing a template on a FusionCompute VM. Use this method only when UltraVR is deployed on a VM that is created on the FusionCompute.

Prerequisites

The FusionCompute installation and initial configuration are complete.
The signature file and digital signature public key have been obtained and the software integrity has been verified.
1. On the page for downloading the UltraVR software package, you can download the .asc digital signature file whose name is the same as that of the software package.
2. You have used the digital signature public key and verification tool provided by the website to verify the digital signature of the software package. You can obtain the digital signature public key, verification tool, and their usage methods from:
  - Enterprise
    Software Digital Signature (OpenPGP) Verification Tool
  - Carrier
    Digital Signature Verification Method
A stable system time is crucial for UltraVR. Do not change the system time when UltraVR is running. If time-hopping occurs, restart UltraVR. For details, see Starting the UltraVR.

Data Preparations

User name and password for logging in to the FusionCompute VM where UltraVR resides.
VM information, as described in Table 1.
UltraVR V100R003C10SPC900_VHD_For_Euler_X86.zip. You can obtain this file from the installation CD-ROM or from the support website. For enterprise users, Click here.

The software package name changes with the actual software version, software package must be the actual version in use.

Procedure

Import VM Template.
1. Decompress UltraVR V100R003C10SPC900_VHD_For_Euler_X86.zip in the maintenance terminal.
  Two files are obtained:
  - UltraVR V100R003C10SPC900_VHD_For_Euler_X86.ovf
  - UltraVR V100R003C10SPC900_VHD_For_Euler_X86-vda.vhd
    
    The UltraVR V100R003C10SPC900_VHD_For_Euler_X86.ovf template file can be imported only to FusionCompute 8.2.0 or later servers.
2. Select the template source.
  1. Log in to FusionCompute. For details, see the FusionSphere Virtualization Suite Product Documentation.
  2. In the dialog box that is displayed, click Import Template.
  3. Select the template source.
    - To import the template from the a shared directory, go to Step 3.1.
      Before importing the template from a shared directory, share the folder that contains VM template on the local PC or network device to the current host user, so that the host can access the template using the network address, and authenticate the template using the username and password.
    - To import the template from the local PC, go to Step 4.1.
      Before importing the template from the local PC, ensure the VM template is stored on the local PC.
3. Configure the importing information about the VM template in a shared directory.
  1. Share the file where the decompressed files reside with the user that has logged in to the maintenance terminal.
  2. Select Shared directory and configure the template importing information.
  - Template Path: Click Select. In the dialog box that is displayed, enter the shared file path, find the ovf file, and press Enter, for example, \\10.10.10.10\share\UltraVR V100R003C10SPC900_VHD_For_Euler_X86.ovf.
  - Username and password: Enter the username and password for logging in to the shared server. If a user account is registered in multiple domains, enter the username with the specified domain name. For example, enter Domain\w00123456.
    After performing this step, go to 1.e.
4. Configure the importing information about the VM template on the local PC.
  1. Select Local PC, and click Choose. In the dialog box that is displayed, find the directory where the template file resides and select UltraVR V100R003C10SPC900_VHD_For_Euler_X86.ovf and UltraVR V100R003C10SPC900_VHD_For_Euler_X86-vda.vhd.
    If you switch to the page for the first time, the template selection module needs loading. Therefore, allow the plug-in to run in the displayed Java information dialog box.
    
    The VM template is transferred between the local PC and a host using the Hypertext Transfer Protocol (HTTP), which provides low security. Therefore, exercise caution when importing or exporting a VM template.
5. Configure the VM Template attributes.
  1. Click Next.
  2. On the Basic Information page, set the VM name, VM creation location, and computing resources.
  3. Click Next. In the Select Data Store area, select Data Store. The available capacity of the datastore must be at least 50 GB.
  4. Click Next. In the Configure Template area, Click Hardware tab page, set CPU, memory, disk, NIC, and graphics chip information.
    Set the data storage and configuration mode of the disk. Set the disk configuration mode to Access or Thin provisioning, and select Independent&persistent.
  5. Click Next.
    The Confirm page is displayed.
  6. Click OK.
    The system starts creating the VM. You can view the task progress on the Task Center page.
    
    The creation process takes about 60 minutes.
    
    During the first installation, the Load Certificate dialog box is displayed. You need to click Load Certificate before continuing the installation.
6. Check whether the OS version of the template VM is EulerOS 2.10 64bit.
  1. Expand the navigation tree on the left, choose Resource Pools, and click VM Template. On the VM Template page, click the template VM name. In the Configure Basic Information area, check whether the OS type is EulerOS 2.10 64bit.
    If yes, go to 2.
    
    If no, go to 1.f.ii.
  2. Click the Configuration tab. The Configuration page is displayed.
  3. Click Settings and change the OS version to EulerOS 2.10 64bit.
Import a VM using a template.
1. Log in to FusionCompute. For details, see FusionSphere Virtualization Suite Product Documentation.
2. On the page, click Deploy VM Using Template.
  The Create VM dialog box is displayed, as shown in Figure 1.
  Figure 1 Creating a VM
3. On the Basic Information page, set Name and Description, select a template, a VM location, and a computing resource.
4. Click Next to go to the Configure VM page.
  - On the Hardware tab page, set CPU, Memory, Disk, NIC, and Graphics Card.
  - On the Options tab page, select Synchronize with host clock. Keep the default values of other options.
5. Click Next. Customize the operating system of the client.
  1. You are advised to select Customize OS for Customize using the Customization Wizard.
  2. Click the Customize Attributes tab and set Computer Name.
  3. Click the NIC Setting tab and set the NIC attributes as planned. The IPv4 attributes can be set at the same time.
    If you select Manually enter IP address, you need to set IP Address, Subnet Mask, and Default Gateway.
6. Click Next.
  The Confirm Info page is displayed. Verify that the information about the VM to be created is correct.
  
  If you need to start the VM after the VM is created, select Start VM immediately after creation.
7. Click OK.
  The VM creation starts. You can click Recent Tasks in the lower left corner to view the task progress.
  - After the task is created, do not refresh the browser until the task is complete.
  - After the browser cache is cleared or the VM is imported for the first time, the certificate of the destination host needs to be loaded. After the loading is successful, click Continue.

Follow-up Procedure

Wait 5 to 10 minutes until UltraVR is started, Log In To UltraVR, if you can log in, the software is successfully installed.
To ensure the system security, after you have installed UltraVR using a template, periodically change the passwords of operating system account DRManager, access database account RDDBUser, and database administrator account GaussDB. For details about how to change the passwords, See the default password of the account for the target node on the Type A (Background) sheet in the UltraVR V100R003C10SPC900 Account List.

The validity period of the DRManager user password is 90 days. Change the password in time.
For security purposes, users may want to use a certificate issued by a third-party certification authority. UltraVR allows users to replace the TLS certificate. Users need to provide the TLS certificate and the public and private key pairs when replacing the certificate.
