Desktop Virtual Machine Configuration

The amount of system disk space required depends on the number of applications required in the base image. Omnissa has validated a setup that included 8GB of disk space. Applications included Microsoft Word, Excel, PowerPoint, Adobe Reader, Internet Explorer, McAfee Antivirus, and PKZIP.
