Before you perform virtual machine cloning, you must create a virtual machine template that the clones are based on.

Prerequisites

Procedure

  1. In vSphere Web Client or vSphere Client, create a new virtual machine.
  2. Configure custom configuration options.
    1. Right-click the virtual machine and click Edit Settings.
    2. Specify the number of vCPUs and the vMemory size.

      For recommended values, follow the guidelines in the installation guide for your Linux distribution.

      For example, Ubuntu 12.04 recommends configuring 2048 MB for vMemory and 2 vCPUs.

    3. Select Video card and specify the number of displays and the total video memory (vRAM).

      Set the vRAM size in vSphere Web Client for virtual machines that use 2D or vSGA, which use the VMware driver. The vRAM size has no affect on vDGA or NVIDIA GRID vGPU machines, which use NVIDIA drivers.

      For recommended values, follow the guidelines in System Requirements for Horizon 7 for Linux. Do not use the Video Memory Calculator.

  3. Power on the virtual machine and install the Linux distribution.
  4. Create a user with root privileges, for example, ViewUser. This user is used to install and uninstall Horizon Agent only.
  5. Edit /etc/sudoers and add the line ViewUser ALL=(ALL) NOPASSWD:ALL.

    With this line in /etc/sudoers, no password is required to run sudo as ViewUser. When you run the sample script to install Horizon Agent that is provided in this chapter, you specify ViewUser as an input.

  6. If the Linux distribution is RHEL, CentOS, or NeoKylin, edit /etc/sudoers and comment out the following lines:
    Defaults requiretty
    Defaults !visiblepw
  7. If the Linux distribution is not RHEL 7, CentOS 7, SLED 12, or SLES 12, install VMware Tools .

    RHEL 7, CentOS 7, SLED 12, and SLES 12 have Open VM Tools installed by default.

  8. If the Linux distribution is RHEL 7, CentOS 7, or SLES 12, install the deployPkg plug-in.

    The instructions are at http://kb.vmware.com/kb/2075048.

  9. For RHEL and CentOS, enable the Network Connection setting Connect automatically.
  10. Perform the AD integration tasks.
  11. Perform the steps to set up graphics.
  12. Install Horizon agent
     sudo ./install_viewagent.sh -A yes
  13. Perform additional configurations using the View configuration files.
  14. Shut down the virtual machine and create a snapshot.
