Overview of this book

VMware vCloud Director is an enterprise software solution that enables the building of secure, private clouds by pooling together infrastructure resources into virtual data centers. The tool enables self-service via a web interface to reduce the management overhead and offers amazing possibilities for production and development environments. Thus, the tool will ensure efficient management of resources with data center efficiency and business agility. "VMWare VCloud Director Cookbook" will cover a lot of ground, ranging from easy to complex recipes. It will not only dive into networks, data-stores, and vApps, but also cover vCloud design improvements, troubleshooting, and the vCloud API. "VMWare VCloud Director Cookbook" is split into different sections, each of which deals with a special topic in vCloud - from networks, to vApps, to storage and design. This book contains over 80 recipes with the difficulty levels ranging from simple to very advanced. You will learn how to automate vCloud easily and quickly with the API, and also learn how to isolate a vApp and still fully access it without risking the network. Design considerations that need to be addressed while deploying the vCloud and more will also be looked into. "VMWare VCloud Director Cookbook" will make your life as an admin a lot easier by providing you with some good recipes that have been proven to work in small to large enterprises.

Making the VM BIOS ID (UUID) unique

The UUID of VMs in vCloud is not unique. In this recipe we will see how to change this.

Getting ready

We need a vCloud environment where we have the need for a unique UUID (see the How it works... section).

How to do it...

  1. Shut down your vCloud environment (all cells).

  2. Log in to your database.

  3. Create a backup of the database.

  4. Run the following SQL statement:

    update config set value = '0' where cat='vcloud' and name='backend.cloneBiosUuidOnVmCopy';

  5. Start your vCloud environment.

How it works...

When you deploy a vApp from a vApp template, the VMs will have the same UUID. The UUID of a VM is stored in the .vmx file of the VM. When vCloud creates a copy of the VM, it will keep the UUID. This is normally not a problem. However, some backup and DR software, such as Comvault, keeps track of the VMs by using the UUID. If you have VMs with the same UUID, this will lead to the problem of backups not working correctly, and restores will be a major nightmare. There are probably...
