virtual network &#8211; which will expose a virtual network adapter to the parent partition without needing to have a physical network adapter associated with it.<\/li>\n<li>Unlike with Virtual Server, Hyper-V only binds the virtual network service to a physical network adapter when a virtual switch is associated with the physical network adapter in question.\u00a0 The advantage of this is that you avoid the performance overhead involved with having this service enabled on network adapters that are not associated with virtual network switches, the downside is that it means that networking gets disrupted on the network adapter in question when a virtual network switch gets created or deleted.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>thanks,<\/p>\n<p>MSGeek<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>With Hyper-V the world of networking is quite different than it was with Virtual Server.
