Hyper-V network adapter differences - TechGenix
If the Hyper-V Network Adapter Name property does not exist, then you are using a down-level guest operating system or a generation 1 VM. Viewing Hyper-V’s Network Device Name in the Guest with PowerShell. As you saw in the preceding section, this field appears with the adapter’s advanced settings. What specific type of network adapter should you choose if you are creating a generation 1 VM and performance is a priority? synthetic When a new network adapter is connected to a virtual network, how is the adapter's MAC address assigned? I am planning out a Hyper-V R2 Cluster environment. I was wondering if I went to the effort of deploying one of the few methods to network boot from iSCSI inside the guests, whether the legacy network adapter would switch to a synthetic after boot, or whether the connection could be handed to a synthetic network after boot? May 27, 2010 · In Hyper-V there are TWO kinds of network adapters inside the virtual machines. First, there is the "Network Adapter" and then there are the "Legacy Network Adapter". The difference between those are very simple. Which of the two types of virtual network adapters, synthetic or emulated, is called the legacy adapter and why? If more than 256 adapters are needed, an administrator can modify the MAC address pool to be larger. For virtual network adapters, Hyper-V assigns a value up to 256 to create individual MAC addresses. I have set up a Hyper-V Linux based webserver VM. I am currently trying to make the webserver available to access on the host machine network with a static IP. Example: Host Network: 10.10.50.xx Gateway: 10.10.50.1. Supposed to be VM IP: 10.10.50.4. Every time I make changes to the adapter on the host machine, the VM will lose Internet connection.

In Hyper-V, the default networking interface card is not the legacy network adapter (which also emulates an Intel 21140 adapter), but instead is the synthetic network adapter. If you attempt to move a virtual machine with the emulated Intel 21140 adapter still installed, the network adapter …
The VM network adapter could be a synthetic virtualization of a network adapter (synthetic network adapter). In this case, the network virtual service client (NetVSC) that runs in the VM exposes this virtual network adapter. NetVSC forwards packets to and from the extensible switch port over the VM bus (VMBus).
Hyper-V – how to install legacy network driver for Windows Feb 03, 2013 Performance Tuning Windows Server 2008 R2 Hyper-V: Network The Hyper-V synthetic network adapter is designed specifically for virtual machines to achieve reduced CPU overhead on network I/O compared to an emulated network adapter mimicking existing hardware. The synthetic network adapter communicates between the child and root partitions over VMBus by using shared memory for more efficient data transfer.
