Custom OS Template (Windows)

An organisation administrator can create a Customised OS Template which can be used for instantiating remote desktops. This is also useful for activating your own licence on your OS.

These steps are essential to create an image successfully. Tread carefully. 

Important:

About Disk Partition
1. Customised template requires only one disk partition,  or two partitions: one is EFI/Boot partition and the other is the system and data partition.
2. LVM partition is not supported, please do not use it.
3. An incorrect partition scheme will cause the disk auto-resize and machine naming features to fail.

 

Windows

1. Install "Red Hat VirtIO SCSI pass-through controller

   When asked "Where do you want to install Windows?", click "Load drivers", then select the correct driver accordingly. After that, the storage drive will appear.

2. Initial Setup

     Click I don't have internet when asked "Let's connect you to a network"

     Click Continue with limited setup when asked "There's more to discover..."

3. Install Virtio-win drivers and guest agents

    Once the machine has started and you are logged in, go to the CD Drive E and run Virtio-win-guest-tools to install the virtio drivers and spice vdagent and qemu guest agent. Click Next and OK to finish the installation.

4. Disable Hibernate 

    Open "Command Prompt" by right-clicking "Run as administrator", type "powercfg.exe /hibernate off" and press Enter.

5. Enable Shutdown/Restart Windows 10 without Any Prompts

     In the registry editor, navigate to this key HKEY_USERS\.DEFAULT\Control Panel\Desktop.

6. Check if the required service exists and set to "Automatic Start"

• Spice-Vdagent : for support of qemu vnc clipboard
• BalloonSerivce:   for guest memory usage stats
