Description: A guest network interface is a virtual network interface assigned to a virtual machine (VM) in a virtualization environment. This interface allows the virtual machine to communicate with other virtual machines, as well as with the physical host and external networks. Technically, it acts as a virtual network adapter that simulates the behavior of a physical network adapter, enabling data transmission and network connectivity. Guest network interfaces are fundamental for the operation of virtual machines, as they facilitate communication and information exchange between different virtual and physical environments. Additionally, they can be configured with different types of connectivity, such as NAT (Network Address Translation), bridging, or internal network, depending on the specific needs of the network infrastructure. This flexibility allows system administrators to optimize the performance and security of their virtualized environments by tailoring the network configuration to the requirements of the applications running on the virtual machines.
