Hi, I found the code. It's a dnsmasq dhcp-script called by dnsmasq for various events, it resides in nova/bin/nova-dhcpbridge and it, among other things, calls release_fixed_ip when the lease expires. On Sat, Aug 18, 2012 at 1:01 AM, Aaron Rosen aro...@nicira.com wrote: Hi Eugene, I'm not

Hi Eugene, I'm not sure I have not looked at the code (I'm guessing that it probably keeps the lease around since it knows the VM is still active instead of recycling the ip address). Though this is just a guess. You should look at the implementation details if you are curious. Aaron On Sat,
