When creating a security lab, I spend a lot of hours troubleshooting this due to a lack of articles and videos, which mostly people use Virtualbox. Hope can help this article too. Let's Start: Step 1: Look first at your host network, to do this: In your Windows environment, open the cmd > type "Ipconfig /all" > look for IPv4 Address. Here's our architecture: Step 2: Configure our bridge in our data center network: Data center > PVE > network > Linux bridge > any desired name Note: dont make any value except to the desired name Step 3: Assigned the bridge and config for the VM's I got two virtual machines, one is Windows, and the other is Linux. Under the virtual machine, I assigned my windows as VM1 while Linux as VM2. Same configuration for both VMs: Virtual machine > Hardware > from Virtio to Intel E1000, and make sure to uncheck the firewall Step 4: Configure the virtual machine inside. Windows:Start the virtual machine > Ctr + Win > type "ncpa.cpl" > properties > IP address you want > subnet mask > ok Verify: Open your PowerShell, then ping the IP address you set. Linux:Setting > Network > gear icon > IPv4 > configure the Address and netmask > apply Verify: Ping the IP address you set If everything is okay, ping the each other, there;s no error Now, if you ping google.com you will fail because what we set-up is to talk the two VM but Isolated. to be able to have internet your two VM, you should add another network device then select vmbr0 which connect to your internet note: if you dont need to connect to the internet you should disabled this then just use the isolated device network Templates let you quickly answer FAQs or store snippets for re-use.
