I have a 3-node setup running Grizzly on CentOS 6.4 (using packstack) and
The "controller" (let's call it "A") also hosts quantum and nova-compute
Quantum agent-list is all ":-)" (Open vSwitch agent, L3 agent, and DHCP

When an instance is launched on "A", it boots as expected and reaches the
When instance is launched on other hosts, it fails to reach the network
(excerpt from the log of a cirros image below, full log on

Starting logging: OK
Initializing random number generator... done.
Starting network...
udhcpc (v1.18.5) started

No lease, failing

cloud-setup: failed 1/30: up 9.78. request failed

The logs don't show anything else than:

WARNING [quantum.db.agentschedulers_db] Fail scheduling network {'status':
u'ACTIVE', 'subnets': [u'33a87588-d491-46e3-bf67-0853d033373b'], 'name':

Setting quantum or nova logging to verbose and debug does not add any
useful information;

Does anyone have any tips what else to look for?
