<Li> Minimum supported version of Red Hat Enterprise Linux is 5.7 . </Li> <Li> Maximum number of supported CPUs for Windows Server and Linux operating systems is increased from four to 64 . </Li> <P> Hyper - V, like Microsoft Virtual Server and Windows Virtual PC, saves each guest OS to a single virtual hard disk file . It supports the older . vhd format, as well as the newer . vhdx . Older . vhd files from Virtual Server 2005, Virtual PC 2004 and Virtual PC 2007 can be copied and used in Hyper - V, but any old virtual machine integration software (equivalents of Hyper - V Integration Services) must be removed from the virtual machine . After the migrated guest OS is configured and started using Hyper - V, the guest OS will detect changes to the (virtual) hardware . Installing "Hyper - V Integration Services" installs five services to improve performance, at the same time adding the new guest video and network card drivers . </P> <P> Hyper - V does not virtualize audio hardware . Before Windows 8.1 and Windows Server 2012 R2, it was possible to work around this issue by connecting to the virtual machine with Remote Desktop Connection over a network connection and use its audio redirection feature . Windows 8.1 and Windows Server 2012 R2 add the enhanced session mode which provides redirection without a network connection . </P>

How can the hyper-v feature be useful in the datacenter
