Windows Server 2012 R2 Hyper-V highlights
Microsoft has traditionally put out point releases to its server operating systems about every two years; Windows Server 2012 R2 will ostensibly show up just over a year after the initial release. Logic would suggest that such a short release cycle would contain little in the way of new capabilities, but in this case, logic has been defied, as the R2 release delivers a significant number of both new and improved features. Hyper-V is just one of the areas with rich improvements. We hit on 10 of the best new features in this slideshow.
The basic architecture of the virtual machine has not changed in a long time. Because operating systems were built to operate physical devices, all VMs emulate broadly supported hardware, such as a specific NIC card or IDE disk controller. Hyper-V in Windows Server 2012 R2 supports the concept of a totally new architecture based on modern hardware with no emulated devices. This makes it possible to add a number of new features, such as secure boot for VMs and booting off of virtual SCSI or virtual network adapters. The catch is that guest support is limited to 64-bit versions of Windows 8 and Windows Server 2012.
