With new HA nova-network code, the following error is arisen during the nova boot instance:

Thanks, for the report, it is supposed to add dhcp_server to the net_attrs before sending them to linux_net. I will try to track down why this isn't happening

[Vish Ishaya (vishvananda)]

Can you try this fix and see if it solves your issue?

[dan wendlandt (danwent)]

As a data point, I was seeing that error as well and Vish's patch fixes the problem for me. Thanks!

[Mike Scherbakov (mihgen)]

Vish,
Your patch fixes the issue for me as well.
