Libvirt is closely connected with dnsmasq, which acts as a DHCP server. dnsmasq writes lease information in the /var/lib/libvirt/dnsmasq directory. Vagrant-libvirt looks for the MAC address in this file and extracts the corresponding IP address. However, there does exist a libvirt API for finding the IP address of a running domain:. 1 Answer. Libvirt does indeed use DNSMasq to handle DHCP. If you're trying to do some advanced configs with DNSMasq, you need to make sure Libvirt is not interfering. Libvirt is a free and open source software which provides API to manage various aspects of virtual machines. On Linux it is commonly used in conjunction with KVM and Qemu. Among other things, libvirt is used to create and manage virtual networks. The default network created when libvirt is used is called "default" and uses NAT (Network.

On a dedicated server — where VMs often need to be publicly accessible — a Bridged network is ideal and allows each VM to bind to its own public IPv4 and IPv6. Libvirt takes care of creating the bridge device and running a DNS and DHCP server for it. The IP address range can of course be customized to suit, as can the bridge device name, though using virbrNN is a common convention. The libvirt documentation shows how to customize this further to enable IPv6 support, static hostnames and more. Arista EOS is supported by the netlab.
