Taken from the KVM docs here...

https://wiki.debian.org/KVM#Libvirt_default_network



If you use libvirt to manage your VMs, libvirt provides a NATed bridged network named "default" that allows the host to communicate with the guests. This network is available only for the system domains (that is VMs created by root or using the qemu:///system connection URI). VMs using this network end up in 192.168.122.1/24 and DHCP is provided to them via dnsmasq. This network is not automatically started. To start it use:

virsh --connect=qemu:///system net-start default

To make the default network start automatically use:

virsh --connect=qemu:///system net-autostart default
