Hi,All I follow the wiki page: https://wiki.openstack.org/wiki/NeutronDevelopment * Eclipse pydev <http://pydev.org/>- Free. It works! (Thanks togong yong sheng <https://launchpad.net/%7Egongysh>). You need to modifyquantum-server <https://github.com/openstack/neutron/blob/master/bin/quantum-server>and__init__.py <https://github.com/openstack/neutron/blob/master/neutron/server/__init__.py>as following: From:*eventlet.monkey_patch()*To:*eventlet.monkey_patch(os=False, thread=False)* but instruction about Eclipse pydev is invalid,as the file has changed,no mokey_patch any more. so what can i do? -- Regards, kkxue -------------- next part -------------- An HTML attachment was scrubbed...
