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 OS licence.

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.
3. The wrong partition scheme will cause disk auto-resize and machine naming features to fail.

 

Windows

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

  When you see the prompt, "Where do you want to install Windows?", click "Load drivers" and choose the correct driver. After that, the storage drive will be visible.

2. Initial Setup

   When asked "Let's connect you to a network", click I don't have internet.

   When prompted "There's more to discover...", click Continue with limited setup.

   Enter any username, but leave the password field blank.

3. Install Virtio-win drivers and guest agents

  Once the machine starts and you're logged in, navigate to CD Drive E and run Virtio-win-guest-tools. This will install the virtio drivers, spice vdagent and qemu guest agent. Click Next and OK to complete the installation.

4. Disable Hibernate 

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