If the guest _does_ then get its IP, I suppose the problem was to do with timing when the instance first booted. </div>

If it doesn't, my next step would be to look in syslog on the network node, to see if the DHCP request is reaching Dnsmasq there, and how Dnsmasq responds to it.</div>

No IP probably means that the DHCP mechanism failed somehow. Are you running a DHCP agent?<br class="">
