Virtualization
- Linux Kernel Now Supports OpenRISC, Nested Virtualization - Linux Kernel 3.1 支援在虛擬機器裡面開啟虛擬機器。
Linux has support for nested virtualization within the KVM (Kernel-based Virtual Machine) hypervisor. This feature, built from AMD's Nested VMX, allows a virtual machine to be run from inside another. Linux will also provide KVM with the ability to tap into the SMEP (Supervisory Mode Execute Protection) of Intel's next-generation Ivy Bridge processors, which should reduce some of the performance overhead typically associated with virtual clients. Users of the Xen hypervisor get some new features as well: Linux 3.1 will be the first to allow Xen-based virtual machines to directly access devices on a PCI bus, a capability previously only available through a patch. It also folds in Xen's Balloon Driver, which can be used to adjust the amount of working memory used by a virtual machine during operation.

- Linux 3.1 released with NFC support - 更特別的是加入 NFC 近場通訊的支援!
For starters, Linux 3.1 provides support for near field communication (NFC) short-range wireless radios. NFC is supported by Android 2.3 and later releases, including a new "Android Beam" peer-to-peer transfer feature in Android 4.0 , and is incorporated in Google's Android-based Google Wallet mobile payment initiative. Some 552 million NFC handsets are expected to ship in 2016, according to ABI Research.
