Hi everybody, I'm using libvirt together with xCAT, on the same host, for testing purposes. xCAT install and manages dhcpd. How libvirt interacts with dhcpd? And if doens't how does the dhcp server of libvirt works, plus where I can find information on how to troubleshot it? Regards, -- “If you're going to try, go all the way.

It runs a separate instance of dnsmasq for each virtual network that is defined within libvirt. Each instance listens *only* on the bridge device that was created by libvirt for that network. IIfi dhcpd has an option that tells it to listen on all interfaces (or to automatically start listening on any new interface that is created), you should disable that option so that it doesn't attempt to listen for dhcp requests on the bridges created by libvirt.
Cool, thanks!! Does it have logs?
