Title:
Nicira plugin: get_port reports wrong port status for extended
switches
Status in OpenStack Neutron (virtual network service):
Fix Released
Bug description:
When using the provider networks extension with the nicira plugin, a
single, large, network might be backed by several NVP logical
switches.
When reading the logical status for a port, the plugin invokes
nvplib.get_logical_port_status. This routine reads a logica port configuraiton
providing the logical switch uuid and the logica port uuid.
The Plugin leverages the fact that nvp logical switch uuid == quantum network
id.
However, this is not always true in the case of extended switches. The
operation then migth a 404 error if the port was being sought on the first
logical switch of the chain, whereas it might be on a different logical switch.
Its state is then set to ERROR whereas it should be 'ACTIVE' or 'DOWN'.
Steps to reproduce:
1) edit /etc/quantum/plugins/nicira/nvp.ini and set max_lp_per_bridged_ls to
a small value, for instance 3
2) restart quantum-server
3) quantum net-create bridged --provider:network_type=vlan
--provider:physical_network=9f5bd279-fcda-44c4-a709-efec63bc6eb9
--provider:segmentation_id=666
4) quantum subnet-create bridged 192.168.0.0/16
5) quantum port-create bridged --name bridged-2; quantum port-create bridged
--name bridged-3
bridged-3 will be created on a 2nd logical switch (the 3rd port on the
1st ls is the dhcp port)
6) user@os-nvp-ctrl:~/devstack$ quantum port-show bridged-3
