There are a number of resources regarding this that I’ve seen on the Web in various blogs but I’m documenting my approach as much for me so I can remember it as for you as well. There have been a number of conferences that I have arrived at expecting to have a hard-wired connection to the internet to find out that there is only a wireless connection available. When your presentation demos are relying on VMs running under Hyper-V on the laptop, this is a showstopper since natively the VMs rely on a hard-wired connection being served up by Hyper-V. So how does one get around this and share the host machine’s wireless connection with the Hyper-V VMs? Again, this is the way I have done it, it certainly is not the only way. It’s simple to setup and once there I can toggle to use the wireless connection for the VM whether the VM is already running, saved or shutdown.
