The Hyper-V role is supported on either a server core or a full installation however server core is recommended due to its increased security.

Hyper-V is available as a role for 圆4 Editions of Windows Server 2008 Standard Enterprise or Datacentre editions (i.e. What are my options for installing Hyper-V?Ī. Live migration requires the failover clustering role to be added and configured on the servers running Hyper-V. Are there any dependencies for Live Migration? It is possible to keep virtual machines online, even during maintenance, which increases productivity for both users and server administrators. This feature enables virtual machines to use jumbo frames up to 9,014 bytes in size, if the underlying physical network supports it. Support for jumbo frames, which was previously available in nonvirtual environments, has been extended to be available on virtual machines. On Intel-based processors, this is called Extended Page Tables (EPT), and on AMD-based processors, it is called Nested Page Tables (NPT). In virtualization scenarios, hardware-based SLAT support improves performance. It provides an indirection layer from virtual machine memory access to the physical memory access. SLAT adds a second level of paging below the architectural x86/圆4 paging tables in x86/圆4 processors. CPU Core Parking enables Windows and Hyper-V to consolidate processing onto the fewest number of possible processor cores, and suspends inactive processor cores. In addition, there is support for Second-Level Address Translation (SLAT) and CPU Core Parking. The increased processor support makes it possible to run even more demanding workloads on a single host. You can now have up to 32 physical processor cores. Hot plug-in and removal of storage requires the installation of Hyper-V integration services (included in Windows Server 2008 R2) on the guest operating system. You can also add and remove both virtual hard disks and physical disks to existing SCSI controllers of virtual machines. By supporting the addition or removal of virtual hard disks and physical disks while a virtual machine is running, it is possible to quickly reconfigure virtual machines to meet changing requirements. Improvements to virtual machine storage include support for hot plug-in and hot removal of the storage. The following list briefly summarizes the improvements to existing functionality in Hyper-V: What existing functionality is changing?Ī.

All virtual machines are stored in the shared storage area, and the running virtual machine state is managed by one of the nodes. This can include an iSCSI or Fiber-Channel Storage Area Network (SAN). In addition, failover clustering requires shared storage for the cluster nodes.

Live migration allows you to transparently move running virtual machines from one node of the failover cluster to another node in the same cluster without a dropped network connection or perceived downtime.
