I'm running based on Grizzly with quantum+OVS+vlan. When I have an active instance in the cloud, I noticed about a periodic keystone query from the compute node with the active instance. Each time, the compute node requests 4 new tokens. Anyone know why this happen ?

I notice some logs in nova-compute.log, but not sure if it is related:

2013-06-04 15:35:52.242 DEBUG nova.network.quantumv2.api [req-abe1ca6d-f282-4ec4-b696-b24006a6367e 8cbad06dd1764bae93612132ca62671d 45a521413d9b43ff888abb7de9878171] getinstancenwinfo() for aabb _getinstancenwinfo /usr/lib/python2.7/dist-packages/nova/network/quantumv2/api.py:366

Thanks. -chen

Looks like a patch for that was merged last week. https://blueprints.launchpad.net/nova/+spec/fewer-networking-token-checks
