Consider using the simulator plugin, which will simulate hosts. You can follow the testing instructions on the Marvin testing page [1], but modify your setup to implement whatever number of hosts you want to test against. From there, you would need to modify the allocator that's enabled. -chip [1] https://cwiki.apache.org/confluence/display/CLOUDSTACK/Marvin+-+Testing+with+Python
