I recently installed the Hyper-V role on a Windows Server 2008 R2 system. As I installed and configured the role, it asked me which Network Adapters I would allow it to use, and I had to check the one-and-only box, because only one adapter is installed.
The setup process recommended I reserve a network adapter for remote access. I was under the impression that this was because it would use the adapters exclusively for the VMs and I would not be able to Remote Desktop in at all!
Well it turns out my virtual machines run great and I can remote into the Hyper-V host no problem. So were they just being conservative, and suggesting I don't waste bandwidth (that the VMs could be using) by having Hyper-V support a Remote Desktop session? At least the adapter I have installed is gigabit.
I do have a dual port Intel Gigabit Lan adapter I could steal from an unused server and swap in. But my "enterprise" is only hobby-sized (40 anonymous web visits per day, VMs generally used only for email, customer testing of web apps, and development). So I don't think it would matter. And is replacing a network card in a Hyper-V host a pain?
What do you think? Is it a big deal not to reserve a network adapter as Hyper-V recommends?
