Two Types of Hyper-V Virtual Network Adapters Hyper-V provides two types of virtual network adapters. Legacy Network Adapter: The legacy network adapter is only available for generation 1 virtual machines. It is an emulated device, meaning that Hyper-V creates a complete digital reconstruction of a common, basic physical network adapter. This adapter type exists for those situations in which there is no way for a particular guest to load the standard Hyper-V network adapter. In most cases, this is for PXE booting Generation 1 virtual machines. Any other cases would involve unsupported operating systems that have no driver for the standard virtual adapter. This adapter is locked at about 100Mbps speed and requires a comparatively high amount of CPU processing, so avoid using it in situations that do not strictly require it. [Synthetic] Network Adapter: Usually only named as a “Network Adapter”, Hyper-V’s synthetic network adapter is a connection between Hyper-V’s VMBus or an IOV Virtual Function and the virtual machine or management operating system. It is substantially faster than the legacy network adapter. Iets using a VHD (so older volume), so if its gen1 VM --> legacy nic
