Hyper-V How-Tos

Set up a Static IP for Hyper V guest OS

Motivation: to ssh to the VM without always figuring out what the VM's current IP is.

Windows' default switch dynamically assigns IP address to Hyper V Vms whenever Windows restarts.
To assign a static IP address to a VM, we need to set up an Internal Switch.

Steps:

1. In Hyper V: Create an internal Switch

2. In Control Panel\Network and Internet\Network Connections
   Configure its IPv4 properties as follows:
   IP address: 192.168.0.2
   Subnet mask: 255.255.255.0
   Default gateway: 192.168.0.1 // router

3. Add the Switches to the VM. Your VM should have two network adapters: one Default and one Internal

4. Log into the VM, configure Networking as follows:
   IPv4->Manual
   Address: 192.168.0.3
   Netmask: 255.255.255.0
   Gateway: 192.168.0.1

Now you should be able to ping to your VM on Windows with static IP 192.168.0.3

Add a new VM to existing Internal Switch

1. In Hyper-V, add the Internal Switch to the VM
2. In the VM, configure the switch as follows:
   IPv4->Manual
   Address: 192.168.0.4
   Netmask: 255.255.255.0
   Gateway: 192.168.0.1

Share files between guest and host OS

2. Add to windows env variable: Name: DISPLAY, Value: localhost:0
