Why? Because traditional security methods do not scale nor do they match the flexibility required in virtualized environments, or directly protect the hypervisor from breaches. At the same time, the first generation of virtualized endpoint protection, firewalls and other threat management products take up too much overhead, which greatly diminishes the benefits of virtualization that most organizations are seeking. They require an instance of their scanners per-VM, taking up critical CPU and memory, and when multiple signature scanners in a single physical host all update signatures at the same time, it creates a scan storm that can bring a server to its knees.
