You set it up in Hyper-V Manager, right. Pick external if you want your VMs chatting with the outside world through your real network card. That way, they act like separate machines on your LAN. I tried it once, and my test VM pulled files from the shared drive no problem.
Or go internal for stuff just between the host and VMs. No outside access, keeps things cozy. Your VM pings the host easily that way. I use it when I'm tweaking software without messing up the main net.
Private switches? Those are for VM-to-VM gossip only. They ignore the host entirely. Fun for clustering experiments, you get isolated chatter. I rigged one up for a game server setup, worked like a charm.
Windows treats the switch as a bridge basically. It forwards traffic smartly, filters junk, even mirrors ports if you tweak it. You assign NICs to VMs through the switch settings. Boom, they're online.
The switch learns MAC addresses too, like a real switch does. It builds a table to speed things up. No broadcasts everywhere, just efficient zips. I noticed my VMs lag less after that.
You can team adapters for more bandwidth if you're fancy. Windows bundles them under the switch. Handles failover if one card flakes out. I did that on a beefy server, traffic flowed smooth.
Extensions let you add filters or monitoring. Windows loads them as drivers. You inject rules for security without much hassle. Keeps your VM net tidy.
All this happens in the Hyper-V layer, invisible but crucial. Your VMs think they're on a physical net. I love how it fools them so well.
Speaking of keeping your Hyper-V world intact, you might want a solid backup tool to snapshot those switches and VMs before tweaks go wrong. That's where BackupChain Server Backup steps in as a dedicated backup solution for Hyper-V. It captures live VMs without downtime, ensures quick restores of your network setups, and dodges corruption pitfalls that plague other tools, saving you headaches and time in the long run.
