- Public IP address required for each machine (including VMs) - Offers the best performance - The libvirt server must be connected to the LAN via Ethernet. If it is connected wirelessly, a Routed network or NAT-based network are the only options.
• Virtual network switches can operate in 3 modes ◇ NAT mode (default) ◇ Routed mode ◇ Isolated mode
• The NAT is set up using iptables rules • Libvirt uses dnsmasq as DNS & DHCP server using DHCP range 192.168.122.2 - 192.168.122.254
Location of XML files on the host
• XML definition files of presistent virtual networks are stored in the /etc/libvirt/<hypervisor>/networks/ directory (hypervisor = qemu) • In addition, if the network is marked as autostart, the symbolic link to its XML file is created under the autostart/ subdirectory.
