Example for Configuring Multiple VMs for a Small Enterprise

Example for Configuring Multiple VMs for a Small Enterprise

Networking Requirements

A small enterprise needs to deploy many office applications. In traditional deployment mode, the enterprise needs to deploy many CT devices and multiple servers for the office applications. As a result, the deployment and maintenance costs are high, and services are inflexible.

Therefore, the enterprise wants to deploy common office applications on multiple VMs of the router to reduce cost on application servers and simplify device management. The VMs provide the same application services as traditional application servers. Figure 5-4 shows the networking.

Figure 5-4  Networking for VM deployment

Configuration Roadmap

To meet the enterprise's requirements, configure virtualization. The configuration roadmap is as follows:
  1. Make a VM installation package online and create two VMs vm1 and vm2.
  2. Configure communication among the routing system, HostOS, and VMs.
  3. Configure VNC and log in to the VMs. Then install the operating system (OS) and applications.

Procedure

  1. Make a VM installation package online.

    # Configure IP addresses for the routing system virtual interface GE0/0/6 and the HostOS virtual interface veth1.

    <Huawei> system-view
    [Huawei] sysname Router
    [Router] dhcp enable
    [Router] interface gigabitethernet 0/0/6
    [Router-Gigabitethernet0/0/6] ip address 1.1.1.1 24
    [Router-Gigabitethernet0/0/6] dhcp select interface

    # Configure IP addresses for the physical interface GE0/0/5 and the virtual interface br0.

    [Router-Gigabitethernet0/0/6] quit
    [Router] dhcp server ping packet 10
    [Router] interface gigabitethernet 0/0/5

    # Check the IP address assigned to the VM.

    [Router-virtual-environment-ovs-br0] port veth4 link-type access
    [Router-virtual-environment-ovs-br0] quit

  5. Log in to vm1 and vm2.

    Perform the same operations to log in to vm2.

    # Open the VNC viewer, enter 10.10.10.254:6, as shown in Figure 5-5.

    Figure 5-5  VM login page on the VNC viewer
    NOTE:
    Before logging in to the VM, ensure that your PC can communicate with the VM.

    # Click the Options button. On the displayed VNC Viewer-Options page, click the Expert tab page.

    # Set FullColor to True, and click OK. The system returns to Figure 5-5.

    # Click Connect and enter the authentication password in the dialog box that is displayed.

    # Click OK to log in to the VM.

    # Install the OS on the VM in the same way you install an OS on a PC.

    # After installing the OS, install applications in the OS.
