Windows Server R2 Hyper-V new features

Microsoft Windows Server Hyper-V has made great strides. In the upcoming Windows Server R2, Microsoft Hyper-V continues to drive its virtualization technology forward, giving us more surprises. To give you an idea of the great progress of the next version of Hyper-V, this article collates the top 10 Hyper-V features in Windows Server R2.

1, the second generation of virtual machines. I think the most cutting-edge thinking enhancements in the new Windows Server R2 Hyper-V are the next generation of virtual machines (VMS). These new generation of virtual machines are specifically built to run as virtual machines only. They discard all the baggage behind the legacy VM, no BIOS, no legacy device. The new virtual machines are UEFI based, and they can boot virtual SCSI or network adapters. The new second-generation virtual machine can only run operating systems in Windows 8 or Windows Server 2012x64 or later.

2, the complete Remote Desktop support. The new version of Hyper-V also provides complete Remote Desktop functionality, even when the network is not available. It is implemented through the consolidation of Remote Desktop support to the Hyper-V management Console. Connect to the VM through the VMBus interface.

3, the virtual machine automatic activation. From Microsoft's first launch of Hyper-V to today, virtual machine activation has been a hassle. However, the new Hyper-V makes it easier to activate the guest VM, which provides the ability to activate automatically.

4, a faster real-time migration. The new Hyper-V version also provides two ways to achieve faster, real-time migrations. First, its VM memory and data can be compressed when performing a dynamic migration. This compression enables real-time migrations to achieve a maximum performance improvement of twice times. In addition, live migrations can leverage high speed networks on High-performance SMB direct functionality to improve performance.

5, online adjustment vhdx size. Another good improvement is the ability to increase and reduce VHDX files without disrupting the end-user's services. This new feature is limited to the new VHDX format and is not available in the old VHD format.

6. Storage quality of service (QOS). Hyper-V in Windows Server R2 provides the ability to provide QoS for storage. Storage QoS enables you to tune I/o-intensive virtual machines to ensure that there are no one or two overly active virtual machines that monopolize the host's storage subsystem.

7, real-time export VM. The new Hyper-V also provides the ability to run virtual machines for real time export. This can help you to clone and move virtual machines more easily. The export process corresponds to a snapshot of the current state of the virtual machine.

8. Extend Hyper-V replication for Dr. Hyper-V replication is one of the most popular features in Windows Server 2012. With Hyper-V in Windows Server R2, you can replicate a target VM that has been replicated from another hyper-V, allowing Hyper-V replication to backup or replicate virtual machines for redundancy. Additionally, Hyper-V in Windows Server R2 allows you to control the interval at which replication logs are sent from source to replication destinations.

9, support USB pass-through. USB pass-through is definitely a feature that every Hyper-V administrator has long dreamed of. The USB pass-through allows you to connect a USB device to a Hyper-V host and then access the USB device from the HYPER-VM guest virtual machine. This can be very handy to install software or quickly replicate data to your Hyper-V virtual machines.

10. Compatibility of Windows Azure IaaS. Windows Azure IaaS uses exactly the same virtualization as Windows Server 2012. This means that the virtual machines deployed locally and running in Windows Azure IaaS are 100% compliant. If your network virtualization is in place, you can even seamlessly migrate the internally deployed Windows Server Hyper-V virtual machines to Windows Azure and migrate back.
