It can be connected to a Network Interface Card. A virtual switch can be deployed as software or as a firmware.
Some of the advantages of virtual switches for network / cloud administrators are:
- It helps virtual servers in deployment and migration
- Easy to roll out hardware, software or firmware related functionality
- Enables network personnel to management virtual switches via hypervisor
