     6{{{
     7Linux has support for nested virtualization within the KVM (Kernel-based Virtual Machine) hypervisor.
     8This feature, built from AMD's Nested VMX, allows a virtual machine to be run from inside another.
     9Linux will also provide KVM with the ability to tap into the SMEP (Supervisory Mode Execute Protection)
     10of Intel's next-generation Ivy Bridge processors, which should reduce some of the performance overhead
     11typically associated with virtual clients.
     12
     13Users of the Xen hypervisor get some new features as well: Linux 3.1 will be the first to allow Xen-based
     14virtual machines to directly access devices on a PCI bus, a capability previously only available through
     15a patch. It also folds in Xen's Balloon Driver, which can be used to adjust the amount of working memory
     16used by a virtual machine during operation.
