This wishlist bug has been open a year without any activity. I'm going to move it to "Opinion / Wishlist", which is an easily-obtainable queue of older requests that have come on. If you decide to work on this consider using a blueprint [1] (with spec [2]). I'll recommend to read [3] if not yet done.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1078909 Title: FEATURE REQUEST: option to limit size of network creation; batch/transaction creation Status in OpenStack Compute (nova): Opinion Bug description: I'm not sure is this is strictly-speaking the right place to file this, but will do so for want of a better alternative for now. I recently made use of the RackSpace OpenStack Private Cloud installer/ISO, Alamo v.1.0.1 During the install process, I was promptes for my [private] network block, and I provided it as 192.168.0.0/8 The install process proceeded (overnight), but was getting nowhere. Upon closer inspection of the process list (`top` & `ps aux`), I found the following to explain the crazy load on the system: "/usr/bin/python /usr/bin/nova-manage network create --multi_host=T --label=public --fixed_range_v4=192.168.0.0/8 --num_networks=1 --network_size=16777214 --bridge=br0 --bridge_interface=eth1 --dns1=8.8.8.8 --dns2=8.8.4.4" note: trying to fill up the *entire* network range of 16+ *MILLION* addresses Found this issue with the help of a very nice RS tech @ IRC. The prevailing consensus is that there should probably be a little bit more smarts in this subsystem - either get verification for networks larger than 1,000 or 10,000 adresses (anything that'll take more than, say, an hour to process; probably not really a possibility for a batch process), or batch the DB process into a transaction to run more efficiently.
