[Yahoo-eng-team] [Bug 1348788] [NEW] network_device_mtu is not applied to VMs, only to agents

2014-07-25 Thread Ian Wells
Public bug reported: (This is using the ML2 driver with the Linuxbridge agent, along with libvirt and KVM. This is likely to be agent-specific, but I think at least some other agents will have the problem.) 1. set Neutron's network_device_mtu to (say) 9000, assuming you've set up an infrastruct

[Yahoo-eng-team] [Bug 1747028] [NEW] Segments extension documentation does not explain why you would want to use it

Public bug reported: https://docs.openstack.org/neutron/pike/contributor/internals/segments.html The segments extension says 'this lets you operate on segments', basically. It doesn't say what a segment is (or refer to external documentation that does) and it does not say why you might want an A

[Yahoo-eng-team] [Bug 1640956] [NEW] RFE: Extension for improving Nova-Neutron callflow to cache port data

2016-11-10 Thread Ian Wells
Public bug reported: Nova requires some data from a Neutron port and its friends to populate its port info cache, and ultimately to create the metadata constructs that are passed on to VMs to inform them of their addresses and routes. Today, it wanders the datastructures in Neutron, looking at por

[Yahoo-eng-team] [Bug 1640960] [NEW] RFE: VIF plugging negotiation between Nova and Neutron

2016-11-10 Thread Ian Wells
Public bug reported: Nova has opinions on which VIF types are acceptable, and these types vary by circumstance. vhost-user can be used if QEMU is in use and hugepages are used on the VM (specifically, if the VM's memory is backed by an open file, in fact); exclusively virtio mechanisms like vhost

[Yahoo-eng-team] [Bug 1464465] [NEW] RFE: binding_type improvements

2015-06-11 Thread Ian Wells
Public bug reported: I'm trying to get a spec approved for Nova that would make it tell us what binding types are available. This would seem like a golden opportunity to clean the interface up. At the moment Neutron works out a binding_type it will tell Nova (which Nova must support or else). N
