What’s new in Windows Server 2012 R2 Hyper-V

On TechEd Windows Server 2012 R2 is announced. Here are some highlights of “Hyper-V – What’s New in Windows Serve 2012 R2” session (MDC-B330):

  • Windows Azure IaaS compatibility—Windows Azure IaaS uses exactly the same virtualization as Windows Server 2012 Hyper-V. So VM’s on-premise can be moved to Azure (Iaas) without problems
  • Generation 2 Virtual Machines (VMs). In the  generation 2 VM are many emulated devices removed and it boots from virtual SCSI or synthetic network adapters. In earlier releases the VM booted from an IDE controller or a legacy network adapter. Gen 2 VM’s are only supported from Windows 8 and Windows Server 2012 64-bit and higher Operating Systems. A generation 2 VM knows that it is virtualized!
  • Enhanced VM Interaction. This is Remote Desktop over VMBUS which enables full remote desktop capabilities such as shared clipboard, copy files, audio redirection, enhanced login etc.
  • Automatic activation. Zero touch activation of VMs.  It will check if the Hyper-V host is licensed than the VM is automatically licensed.
  • Faster Live Migration (LM). Faster LM by using compression, improves 2x the LM time. Compression is enabled by default. SMB direct (RDMA) can be used in high-end networks that require super high-speed LMs.  As guidance use for 10 Gbit or less network compression and over 10 Gbit use SMB/ SMB direct

  • Online VHDX resize. Increase and decrease the size of the virtual hard disks while the VM is running
  • Live virtual machine export / clone. While the VM is running, it is possible to export a complete copy of the VM including the memory state and export any snapshot of a VM.
