Hyper-V Version FeatureDescriptionUpstream 2008 R2 + TCP Offloading Transfers some of the workload from the CPU to a network adapter during network data transfers. Spring D video driver Provides enhanced graphics performance and superior resolution for Linux desktop users Dynamic Memory – Hot add Dynamically increase the amount of memory that is available to a live virtual machine. Spring 2013 vRSS Virtual Receive-Side Scaling spreads the load from a virtual network adapter across multiple virtual processors in a virtual machine. Spring R2 + Generation 2 VM Support Allows Linux virtual machines to be run in UEFI enabled Generation 2 mode. Spring 2014 File Copy from Host to Guest Allows copying of files from host to guest without using the network interface. TRIM support Allows Linux virtual machines to optimize storage consumption through technologies such as Thin Provisioning. Particularly useful for Linux virtual machines hosted in Azure. Fall 2013 Online VHDX resize Allows expansion of live mounted fixed sized Linux VHDs. Spring 2013 Virtual fibre channel Allows Linux virtual machines to natively access high speed fibre channel networks. Online backup Facilitates zero down time backup of live virtual machines to Azure.

Hyper-V Version FeatureDescriptionStatus 2008 R2 + Enhanced Time Synchronization Avoids clock drift issue by ensuring VM's time is kept synchronized with the maintained time on the host using host time sample. Upstreaming Network Performance Improvements New offloads and network optimizations to improve performance for 10Gbps and above network cards. In Progress SR-IOV Maximizes network throughput while minimizing network latency as well as the CPU overhead required for processing network traffic. Kicking Off Windows Server v.Next Secure Boot Enables secure boot feature for Linux VMs using UEFI which has the boot loader signed with a Microsoft key as the root of trust. Windows Server v.Next Hot Add/Remove Synthetic NIC Manually add/remove virtual NICs when the VM is running. Azure Infiniband Infiniband driver for Linux guests supports high performance computing running on Azure version of Hyper-V. Azure v.Next

Helps prevent unauthorized firmware, operating systems, or UEFI drivers from running at boot time. With Windows Server v.Next, Linux VMs with a signed boot loader will have the option to leverage secure boot. Canonical and SUSE signed their boot loaders with the Microsoft UEFI CA. Enabled by default for generation 2 virtual machines. Set Certificate through power shell.

Eliminating workload downtime due to reconfiguration Hot add a virtual disk introduced in Windows Server 2008 R2 Hot add memory introduced in Windows Server 2012 R2 Hot add a network adapter introduced in Windows Server v.Next
