The key challenges of server virtualisation

Overview

Server virtualisation has made giant strides over the past decade, creating heroes inside IT organisations. Accordingly, it's no surprise that interest in the technology remains as strong as ever.
Indeed, respondents to a recent survey ranked "increased use of server virtualisation" as their number one IT priority over the next 12-18 months. However, despite the broad success of server virtualisation, nagging issues and challenges exist. As a result, a low percentage of the potential workloads that can be virtualised have been migrated to virtual machines, and the consolidation ratios of virtual machines per physical server remains relatively low.
