What device do virtual machines use to connect to the virtualized switching environment?

In virtualization, the VM connects to the virtual switching environment through its virtual network interface card. This virtual NIC is the guest OS’s network adapter, presented by the hypervisor as a real NIC inside the VM. It plugs into a virtual switch inside the host, which bridges traffic between all the VMs’ vNICs and, if configured, uplinks to physical networks. The virtual switch handles the actual switching, but the VM’s connection point is the virtual NIC. A physical NIC is the host’s real hardware edge and isn’t the VM’s internal connection, and a router isn’t the interface the VM uses to connect to the vSwitch, though a router can route traffic after it leaves the virtual switch.
