Conductor support for networking on Icehouse

[Matt Kassawara]

I'm updating the installation guide for Icehouse. Based on the following blueprint, I removed the database configuration keys from nova.conf on the compute node in my test environment.

https://blueprints.launchpad.net/nova/+spec/nova-network-objects

However, when attempting to boot an instance, the Nova network service fails to retrieve network information from the controller. Adding the the database keys resolves the problem. I'm using the 2014.1~b3-0ubuntu1~cloud0 packages on Ubuntu 12.04.

Here's my network configuration and instance boot information:

matt@hst-osctl5:~$ nova net-list

Due to size, I'm attaching the output from nova-network.log when attempting to boot an instance.

    Add get_by_network() to FixedIPList

    This adds support for get_by_network() to FixedIPList, which is needed
    by the linux_net module to go full-objects. Since it depends on
    information in the VirtualInterface object, this also adds a nested
    FixedIP.virtual_interface object, which currently is only reachable
    when queried in this way.

    Make linux_net use objects for last fixed ip query

    This converts the final uses of direct database calls from the
    linux_net module by utilizing the calls just added to the
    FixedIP object.

    Block database access in nova-network binary

    This mirrors the code we have in cmd/compute.py to wedge the database
    module so that we can't add any more direct calls, and will highlight
    any stragglers.

I still cannot launch an instance using nova-network after removing the database configuration keys from nova.conf on a compute node. Attaching output from nova-compute.log for analysis.

[Matt Kassawara (ionosphere80)]

This bug was marked "fix released" with RC1 milestone, so I assumed RC1 would work without database access on the compute node. However, apparently a patch in RC2 addresses this issue. I'll test again after Ubuntu releases RC2 packages.

[Matt Kassawara (ionosphere80)]

Bug still valid on Ubuntu with 2014.1-0ubuntu1~cloud0.
