[Yahoo-eng-team] [Bug 1257788] Re: nova-network doesn't handle large amount of concurrent booting instances well
This has been fixed by some of the work to move nova-net to objects. ** Changed in: nova Status: Triaged = Fix Released ** Changed in: nova Assignee: (unassigned) = Dan Smith (danms) -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1257788 Title: nova-network doesn't handle large amount of concurrent booting instances well Status in OpenStack Neutron (virtual network service): Invalid Status in OpenStack Compute (Nova): Fix Released Bug description: As seen by the large-ops test nova-network has trouble booting 150 VMs concurrently. Part of the problem is that setting up the network for each instance is relatively expensive with many locks and root-wrapped calls. Both of which significantly hurt performance. One possible fix would be to do more bulk network operations when possible, so instead of 100 separate calls to a root-wrapped tool call it once.

Setting as Invalid for neutron since the bug description doesn't provide exact issues encountered. ** Changed in: neutron Status: Triaged = Invalid -- You received this bug notification because you are a member of Yahoo!

Setting this to a low priority because workarounds exist (run more nova-networks) and because nova-network is frozen. ** Changed in: nova Importance: Undecided = Low ** Also affects: neutron Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
