[Bug 1482092] [NEW] oslo_versionedobjects raise exception when boot instance with nova-network

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

oslo_versionedobjects will raise TypeError exception when boot instance
with nova-network.

I'm using devstack with
nova:  00af05e13f5f0a2d8d10baf238dad553a86bc6e0
oslo_versionedobjects: 5.2

Nova had remove VirtaulInterface's super class base.NovaObjectDictCompat
https://github.com/openstack/nova/commit/91f8cc9c153b61a5aed081c2d1b44b21f35d3311
It can work above oslo_versionedobjects 6.0.

But oslo_versionedobjects 5.2 still using dict to assign value.
https://github.com/openstack/oslo.versionedobjects/blob/0.5.2/oslo_versionedobjects/base.py#L205

Maybe we should update oslo_versionedobjects version in global-
requirement.
