This is a bug. The dhcp least time flag is supposed to be used in place of the 120s.  It must have been removed at some point.


Can you please file a bug on launchpad.  If  you are able to submit a review request in gerrit as well, that would be fantastic.

hi:
when i use DHCPflat mode,the instance to get ip in fews times
in the log of nova-network.log like this:

2011-11-23 13:33:30,840 DEBUG nova.network.manager [8d6b0be9-1ae7-4f69-a10c-c4d6a42ebc55 None None] Leased IP |10.0.0.22| from (pid=12204) 
lease_fixed_ip /usr/lib/python2.7/dist-packages/nova/network/manager.py:642

2011-11-23 13:34:14,850 DEBUG nova.network.manager [cf1929d3-03c5-427f-b41b-beef610b0db2 None None] Leased IP |10.0.0.22| from (pid=12204) 

lease_fixed_ip /usr/lib/python2.7/dist-packages/nova/network/manager.py:642


when i change the flag "dhcp_lease_time" in the "network/linux_net.py "
 58 flags.DEFINE_integer('dhcp_lease_time', 12000000,
 59                      'Lifetime of a DHCP lease') 

it's still 120s
dnsmasq --strict-order --bind-interfaces --conf-file= --domain=novalocal --pid-file=/var/lib/nova/networks/nova-br1.pid --listen-

address=10.0.0.3 --except-interface=lo --dhcp-range=10.0.0.2,static,120s --dhcp-lease-max=512 --dhcp-

hostsfile=/var/lib/nova/networks/nova-br1.conf --dhcp-script=/usr/bin/nova-dhcpbridge --leasefile-ro



so i change this(in network/linux_net.py ):
626            '--dhcp-range=%s,static,120s' % network_ref['dhcp_start'],
626            '--dhcp-range=%s,static,%d' % (network_ref['dhcp_start'],FLAGS.dhcp_lease_time),  

it's work well

dnsmasq --strict-order --bind-interfaces --conf-file= --domain=novalocal --pid-file=/var/lib/nova/networks/nova-br10.pid --listen-address=192.168.0.6 --except-interface=lo --dhcp-range=192.168.0.2,static,12000000 --dhcp-lease-max=256 --dhcp-hostsfile=/var/lib/nova/networks/nova-br10.conf --dhcp-script=/usr/bin/nova-dhcpbridge --leasefile-ro
