Creating a VM with Virt-Manager: Accessing Internet Host Devices over LAN
In this article, we will discuss the process of creating a virtual machine (VM) using Virt-Manager, with a focus on accessing internet host devices over a local area network (LAN). This is especially useful for testing purposes, where you want to create a VM that can access the internet, but you want to avoid the risks associated with visiting questionable websites or downloading infected files directly on your host machine.
Prerequisites
Before we begin, make sure you have the following prerequisites in place:
- A host machine running a Linux distribution that supports libvirt and Virt-Manager
- A LAN connection between the host machine and the VM
- Sufficient resources (CPU, memory, and storage) to run the VM
Creating the VM
To create a new VM in Virt-Manager, follow these steps:
- Launch Virt-Manager and click on the "New" button to create a new VM.
- Select "Local install media" as the installation source and click "Forward".
- Select the ISO file for the operating system you want to install on the VM and click "Forward".
- Enter a name and description for the VM and select the amount of memory and number of CPUs to allocate to the VM. Click "Forward".
- Select the type and size of the disk for the VM and click "Forward".
- Review the summary of the VM configuration and click "Finish" to create the VM.
Configuring the VM for Internet Access
To configure the VM for internet access over the LAN, follow these steps:
- Select the VM in Virt-Manager and click on the "Details" button.
- Click on the "Add Hardware" button and select "Network Interface" from the drop-down menu.
- Select "Host device" as the network source and choose the LAN interface from the drop-down menu. Click "Apply" to save the changes.
- Start the VM and install the operating system as you normally would.
- Once the operating system is installed, configure the network settings to use the LAN interface as the primary network device. This will allow the VM to access the internet through the host machine's LAN connection.
Testing the VM's Internet Access
To test the VM's internet access, open a web browser in the VM and navigate to a website. If the website loads correctly, then the VM has successfully been configured for internet access over the LAN.
