vif type unbound not supported when creating server

[Stefan Nica]

Creating a vmware server (using stable/newton packages) fails with the following error logged in nova-compute.log:

My initial investigation reveals that this started acting up in nova/stable/newton only after this following neutron patch was backported to neutron/stable/newton: https://review.openstack.org/#/c/470297/

If I manually restore these two changes in neutron/plugins/ml2/driver_context.py and restart neutron-server, I no longer see the problem:

        self._binding = copy.deepcopy(binding)
        self._binding_levels = copy.deepcopy(binding_levels)

[Kevin Benton (kevinbenton)]

Something must be different about how the vmware driver is doing port binding. I need someone with VMware expertise to take a look at this.

[Gary Kotton (garyk)]

Hi,
Can you please let us know which neutron plugin you are using? If this is the ML2 plugin then which drivers?
Thanks
Gary

[Gary Kotton (garyk)]

Please also see https://bugs.launchpad.net/networking-midonet/+bug/1700448

[Stefan Nica (stefan.nica)]

My setup is using the ml2 plugin, with both vmware_dvs and openvswitch mechanism drivers enabled. This is the ml2 section of my ml2_conf.ini:

[ml2]
type_drivers = vlan,vxlan,gre,flat
tenant_network_types = vlan,vxlan,gre
mechanism_drivers = vmware_dvs,openvswitch,l2population
extension_drivers = port_security

I should also note that I'm using a vlan network - the only type of network supported by the vmware_dvs driver - so there's no confusion about the type driver involved.

When vmware_dvs is configured, nova should receive a VIF type of 'dvs', but receives a 'unbound' value instead, which is the immediate cause of the error.

[Kevin Benton (kevinbenton)]

Fixed in https://review.openstack.org/#/c/486867/

[Kevin Benton (kevinbenton)]

@Sean,

Can you remove Nova? This is purely a Neutron/driver bug. Nothing to do on the Nova side.

[YAMAMOTO Takashi (yamamoto)]

I confirmed the symptom seen in bug 1700448 was fixed

[Stefan Nica (stefan.nica)]

This issue has been fixed in Newton, but it's still reproducible in Pike. The simplest solution would be to revert https://review.openstack.org/#/c/441231/ from Pike the same way that https://review.openstack.org/#/c/470297/ was reverted in Newton. Kevin, do you agree with my assessment ?

[Stefan Nica (stefan.nica)]

Actually, for Pike, it will not be enough to revert https://review.openstack.org/#/c/441231/, we also need to revert https://review.openstack.org/#/c/441231, which is an update of the previous one.

Hello All,

I've made some fix to networking_vsphere to make it work with newer neutron-server releases.

I've made the following fixes on stable/rocky branch:

https://review.opendev.org/#/c/695676/

It includes also small fixes to add LACP portchannel support
