Explanation

To establish a private, isolated network between KVM virtual machines on the same host, Linux networking tools are used to create and manage virtual network bridges and TAP interfaces. According to KVM and Linux virtualization documentation, the core components required are brctl, tunctl, and ifconfig (or the modern ip command). The brctl utility is used to create and manage Linux bridge interfaces, which act as virtual switches connecting multiple virtual machines. tunctl is used to create TAP interfaces that allow virtual machines to connect to the bridge. ifconfig is used to bring interfaces up and assign network parameters. ebtables is not strictly required for creating a private network; it is used for filtering Ethernet frames. ipconfig is a Windows networking command and is not applicable to Linux systems.
