Tap networking uses the tap device in the host to provide networking capabilities to the guest. Bridge networking can be used when we would like network devices to see our virtual machines. Socket networking can be used to create guest virtual machines that can see each other over the network. So QEMU is going to get it's private LAN IP from the corporate or WiFi DHCP server, right? Well, not exactly. Although our configuration file will look absolutely identical to if it were working this way, the truth is that by default, QEMU sets up it's own LAN that's only shared by the host computer, and your QEMU virtual server.A default network helper is introduced that implements the same functionality as the common qemu-ifup script. It creates a tap file descriptor, attaches it to a bridge, and passes it back to QEMU. This helper runs with higher privileges and allows QEMU to be invoked as a non-privileged user.QEMU / KVM: Requested operation is not valid: network default is not active.
