10 Deploying Virtual Desktop Master Image
10.1 Creating Template VM
Suggested on the basis of user types used by Dell.
NOTE: Solution is provided on the basis of using full clones for persistence (Standard provisioning) and
recommended disk format is VMDK. Ensure Master image is placed in the same container as the Desktop
pool for faster deployment
Provision a Gold image by doing the following:
Machine Creation Services - Master Image
1. Create Base VM (specify Disk size, Network, Memory, and so on)
2. Install Windows 8.1.
3. Add VM to the Domain.
4. Activate Windows 8.1.
5. Install VMWare Tools.
6. Install the VMware View 6.0.0 agent using the 32bit or 64bit versions as required.
7. Install any required application software including antivirus software and activate if required.
8. Optimize Windows 8.1 using VMWare Optimization best practices.
9. When all optimization tasks have been completed, open an administrator command prompt and type
ipconfig /release to release the IP address and shut down the VM.
10. If a pool of full virtual machine clones is being created; in the vSphere Client, right-click the VM and
select Template, and then click Convert to Template. A VM must be in template form in order for
VMware View to use the VM to create a pool of full clone desktops.
10.2 Optimizing Desktop OS
Ensure you use the VMWare desktop optimization script which can be downloaded from the VMWare
website which can be used to optimize desktop settings for a VDI environment including disabling
unnecessary services.
Windows 8.x Optimization
A new feature in Win 8.1 is Automatic Windows Maintenance, which is a feature of the dism tool that
checks the system and application for update compatibility and file integrity. By default, the system
scheduled task runs at 1 a.m. everyday, or any time after 10 min of idle time. When the system is
functioning, the tiworker.exe process consumes 100 percent CPU on any recently booted desktop
VMs, possibly overloading servers.
