Changing the hardware resources on a running VM

Each virtual machine (VM) is a collection of resources provided by the infrastructure layer, usually organized in a pool of resources and assigned dynamically (or in some case statically) to each VM. VMs “see” a subset of physical resources in a form of virtual hardware components defined usually by the certain minimum elements. Adding hardware components can be useful in some cases, or they can be necessary for performing some basic operations, like, for example, installing the guest OS where a video driver, a keyboard and a mouse device are needed to use the remote console. That is why you should be aware of which hardware resources can be hot-add and which hot-remove.

SMB Direct in a Windows Server 2016 Virtual Machine Experiment

Ever since Windows Server 2012 we have SMB Direct capabilities in the OS and Windows Server 2012 R2 added more use cases such as live migration for example. In Windows Server 2016, even more, workloads leverage SMB Direct, such as S2D and Storage Replication. SMB Direct leverages the RDMA capabilities of a NIC which delivers high throughput at low latency combined with CPU offloading to the NIC. The latter save CPU cycles for the other workloads on the hosts such as virtual machines.
