SELinux-secured virtualization

Virtualization is part of many infrastructural services. Ever since its inception in the early 70s as a means of isolating workloads and abstracting hardware dependencies, virtualization implementations have grown. When we look at service offerings today, we realize that many cloud providers would be out of service if it weren't for virtualization.

One of the services that virtualization offers is isolation, which SELinux can support and augment quite nicely.

Introducing virtualization

When we look at virtualization, we look at the abstraction layers it provides in order to hide certain resource views (such as hardware or processing power). Virtualization contributes to the development of more efficient hardware usage (which results in better cost control), centralized views on resources and systems, more flexibility in the number of operating systems that the company can deal with, standardization of resource allocation, and even improved security services.
