managing compute nodes

Hi. I'm having launching an instance on compute nodes. Initially I set up three node, controller,network and compute. Launching instances worked fine and still works fine. Now I added 2 more compute nodes, say compute2 & 3. I want to launch instance on these added nodes but it seems that it only tried to launch on original compute node. I have already launched a few on compute1, so whenever I try to launch more, it says it doesn't have enough resources. I can see on my dashboard that compute2,3 are connected, and count their resources. Isn't nova-scheduler should assign an instance to any node that has enough resource for that instance? Any cofig should I change to do that? I will provide any more information needed
