How do virtual machines communicate on host server in Hyper-V over COM ports?
Computers that use the Hyper-V virtualization technology can have virtual COM (communication) ports.
These connect virtual machines (VMs) to serial devices on the host machine, such as modems, barcode scanners, and printers. The COM ports appear as if they were physically attached to the VM, but they actually use the host machine’s resources to communicate.
How do two virtual machines communicate on the host server in Hyper-V?

For two virtual machines to communicate on a host server in Hyper-V, they must be connected to the same virtual switch.
There are two ways to do that:
1) creating a new virtual switch and connecting both virtual machines to it, or
2) connecting both virtual machines to an existing virtual switch.
Hyper-V networking best practices
As more and more companies move to a virtualized environment, it’s important to understand how virtual machines communicate on a host server. Here are some best practices for Hyper-V networking to ensure optimal performance and security:
1. Use quality hardware: When setting up a Hyper-V environment, it’s important to use quality hardware that is compatible with the software. This will help ensure smooth communication between virtual machines.
2. Create separate networks: It’s best to create separate networks for each type of traffic, such as public and private traffic. This will help ensure that traffic is segregated and does not impact the overall network’s performance.
3. Configure security: Configure security settings properly to help protect the network from potential threats.
4. Monitor traffic: It’s important to monitor network traffic regularly to identify potential problems and make necessary changes.
Hyper-V external switch no internet

I have a VM I created in Hyper-V that runs Windows Server 2016. The VM has an external switch assigned to it, and I am trying to access the internet from the VM, but I am not having any luck.
I can’t find anything that says how to configure the external switch so that the VM can access the internet.
How to create a virtual network adapter in windows 11
A virtual network adapter is a software that helps connect a virtual machine (VM) to a network. It can be installed on a physical machine or a host server to communicate between VM and the outside world.
There are many benefits of using a virtual network adapter, such as connecting to a corporate network from home or connecting multiple VMs to each other.
