Nested virtualization allows you to run virtual machines (VMs) inside a VM. This can be useful for various scenarios, such as testing and development, running specialized VMs within a larger VM, or for creating isolated environments for testing or debugging.
Here’s a general idea of how nested virtualization works in Azure:
Host VM: The physical Azure virtual machine (VM) serves as the host for nested virtualization. You create this VM just like any other VM.
Enabling Nested Virtualization: To enable nested virtualization on an Azure VM, you typically need to meet certain requirements and perform specific configuration steps. Here are some key requirements and steps:
The host VM must meet certain hardware requirements to support nested virtualization. For example, it must be running on a certain generation of hardware.
You need to enable nested virtualization in the host VM. This usually involves running specific PowerShell commands or using Azure CLI extensions. The exact steps may change over time, so it’s essential to refer to the Azure documentation or the Azure portal for the most up-to-date instructions.
Creating Guest VMs: Once nested virtualization is enabled, you can create and run guest VMs within the host VM, just like you would on a physical server. These guest VMs can be Windows or Linux VMs.
Performance Considerations: Nested virtualization can introduce some performance overhead, as the host VM must manage the virtualization of the guest VMs. It’s essential to consider the resource allocation and performance requirements of your nested VMs.
Networking: Configure the networking for your nested VMs as needed. You may need to set up network address translation (NAT) or other networking configurations to ensure proper connectivity
