Week 2 - Networking Connection Types

 In the process of virtualization, being able to not only simulate an environment with hardware is important, but being able to use different network functionality is a key component. In this post, I will go a bit over how this is going to happen 

When it comes to virtual machines, these machines need to be able to connect to the network based on the hardware that is being virtualized. To accomplish this, there needs to be virtual network interface controllers vNICs that can connect both virtual and physical machines. The amount of virtual network interface controllers that can be utilized is dependent on the hypervisor being used. There are also virtual switches that are used in the host's hypervisor that enable the vNICs to connect to networks.  A singular host is capable of supporting multiple different virtual machines as well. 

There is also a bridged mode that is used to make the vNIC access a physical network while using the host machine's NIC. What this does is create a link between the virtual interface and the physical interface. The vNIC pulls its own networking information from the DHCP server, which assigns the IP addresses to the clients on the network.
