Why we need the cache code in the vsctl code?
Because we need python version of 'vsctl list-ports/add-port/del-port/set/get/find/'. - It's not so simple to manipulate ovsdb in transactional way. OVS db binding(both C and python) is designed such that transaction abort needs to be handed by client. Python couter part is also necessary. - cache code. It is necessary to find out if a given port is on a given bridge due to vswitch db schema. It needs to build a tree from bridge table, to port table and interface table. I also found that quantum_adapter doesn't work well. I put some work around into it for now. It assumes that single ovsdb has a single ovs bridge. But it's not correct. Now quantum-agent creates br-int, br-ex. And other ovs bridge depending on configuration. But I don't see easy fix for that, and think the right fix would be to create the tree of bridge-port-interface - layering bridge and vsctl In long term, OF-config would be supported. I envisage something like bridge-ovsdb and bridge-ofconfig. -- yamahata ------------------------------------------------------------------------------ Don't let slow site performance ruin your business.
