Hi Adam, cool stuff! Thanks for reporting the issues. I'm in favor of both changes your suggest. Any interest on working on the openstack common stuff? More details inline.

Much of this existing code was ripped from nova/glance/etc. and is probably now out of date. I created a page in the wiki identifying areas in quantum that are ripe for using openstack-common: http://wiki.openstack.org/QuantumOpenstackCommon .

Jason Koelker will be leading a session in the Quantum track on redesigning the client, if folks are interested in helping out. > > > > Here's the HTTP error log if I don't make the above change: > > > [Thu Apr 12 11:21:13 2012] [info] Initial (No.1) HTTPS request received > for chil > d 7 (server ayoungstack.bos.redhat.com:443) > [Thu Apr 12 11:21:13 2012] [info] [client 10.16.187.36] mod_wsgi > (pid=8747, proc > ess='', application='ayoungstack.bos.redhat.com|/quantum/api'): Loading > WSGI scr > ipt '/var/www/cgi-bin/quantum/api'. > [Thu Apr 12 11:21:13 2012] [error] > ERROR:quantum.extensions.extensions:Extension > path "/etc/quantum/extension" doesn't exist! > [Thu Apr 12 11:21:13 2012] [error] > WARNING:quantum.extensions.extensions:extensi > on file portstats.py wasnt loaded due to cannot import name extensions > [Thu Apr 12 11:21:13 2012] [error] > WARNING:quantum.extensions.extensions:extensi > on Cisco Nova Tenant not supported by plugin > <quantum.plugins.openvswitch.ovs_qu > antum_plugin.OVSQuantumPlugin object at 0x7f1fae80e450> > [Thu Apr 12 11:21:13 2012] [error] > WARNING:quantum.extensions.extensions:extensi > on Cisco Port Profile not supported by plugin > <quantum.plugins.openvswitch.ovs_q > uantum_plugin.OVSQuantumPlugin object at 0x7f1fae80e450> > [Thu Apr 12 11:21:13 2012] [error] > WARNING:quantum.extensions.extensions:extensi > on Cisco Multiport not supported by plugin > <quantum.plugins.openvswitch.ovs_quan > tum_plugin.OVSQuantumPlugin object at 0x7f1fae80e450> > [Thu Apr 12 11:21:13 2012] [error] > WARNING:quantum.extensions.extensions:Did not > find expected name "Extensions" in > /opt/stack/quantum/quantum/extensions/extens > ions.py > > > _______________________________________________ > Mailing list: https://launchpad.net/~openstack > Post to : openstack@lists.launchpad.net > Unsubscribe : https://launchpad.net/~openstack > More help : https://help.launchpad.net/ListHelp > > -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Dan Wendlandt Nicira, Inc: www.nicira.com twitter: danwendlandt ~~~~~~~~~~~~~~~~~~~~~~~~~~~
