| thorst | yes, all neutron plugins need to be installed on both the compute side (or if they're controlling something else...wherever the thing is that they control) plus the controller side | 11:56 |
| thorst | this is so that you allow the server to see the agents mechanism driver. | 11:56 |
| thorst | you just don't notice with Linux Bridge or OVS because those are the only two in neutron itself. | 11:57 |

| thorst | I can't ping it at the moment, not sure if cloud problem or expiration issue | 12:38 |

| thorst | I think we should submit that today. | 13:15 |
| thorst | than add us to the Thursday IRC meeting for nova | 13:15 |
| efried | thorst, yes, I reviewed it. | 13:17 |
| thorst | efried: excellent | 13:17 |
| efried | Did esberglu update the history? | 13:17 |
| thorst | efried: dont' think so yet. I'll also do that though today | 13:17 |

| viclarson | so on controller side i d have two mech drivers configured? mechanism_drivers = pvm_sea,linuxbridge | 13:40 |
| viclarson | than i have this error on controller side: | 13:41 |
| viclarson | ibmveth 30000002 eth0: tx: h_send_logical_lan failed with rc=-4 | 13:41 |
| viclarson | what does it mean? | 13:41 |
| thorst | viclarson: where is your controller running? on a PowerVM LPAR? I thought it was an x86 controller (or a bare metal Power box)? | 13:48 |
| *** clbush_ has quit IRC | 13:49 | |
| viclarson | on a powervm lpatr | 13:49 |
| viclarson | on a powervm lpar | 13:49 |
| thorst | Okay - I'm betting the problem is the following. (seroyer - please keep me honst) | 13:52 |
| thorst | PowerVM doesn't allow the virtual ethernet to send other mac addresses through it unless its a trunk adapter. You're running this as a client VM so its not a trunk adapter, so when the Linux Bridge you put on top tries to send stuff from other virtual addresses it hits that issue. | 13:53 |
| thorst | seroyer: Is that right? | 13:53 |
| seroyer | thorst, plausible. | 14:01 |
| thorst | seroyer: so if it is a controller we probably need a dedicated card for now? | 14:02 |
| thorst | if you're hosting DHCP, metadata, etc... on it | 14:02 |
| thorst | like we need attached I/O for network nodes | 14:02 |

| efried | thorst, here's a thing I'd like to do in the SR-IOV neutron agent: | 14:22 |
| efried | Right now we've got _report_state happening on a fixed interval (default 30s). In newton, the rpc_loop is updating the pport label in the agent every 2s. So it could be as much as 32s after a pport update where we could be deploying vnics to the wrong pports. | 14:25 |
| efried | Proposal: have an event handler explicitly invoke _report_state when the pport labels change. | 14:26 |
| efried | Bring that gap down to subsecond. | 14:26 |
| thorst | well, I'm good with that as back burner work :-) | 14:26 |
| efried | Fairly small change, really. | 14:27 |
| thorst | OK | 14:32 |
| viclarson | how to configure vm to access trunk adapter? | 14:35 |

| thorst | the second nic (MGMTSWITCH) is for the RMC adapter. The eth0 should get configured with flat_injected set to true. Also can set the force_config_drive=True | 16:09 |

| thorst | seroyer: I'm getting this error when I live migrate with your latest code. This kinda looks like REST, though I have verified that I am santizing the mac properly (it appears something in the core/rest is lower casing it) | 20:13 |
| thorst | "The 'Migrate' operation failed. [PVME01040531-0861] Virtual Ethernet adapter with MAC address fa163ed29e3d is not found." | 20:13 |
| thorst | apearson: ^^ | 20:13 |
| seroyer | That’s my code. I strip colons and lower case for the sake of making the comparison easier. | 20:14 |
| seroyer | thorst ^^^ | 20:14 |
| thorst | seroyer: need the logs I assume | 20:14 |
| seroyer | Does that MAC look correct? i.e., that VM actually has that MAC? | 20:15 |
| thorst | pvmctl vea list --> FA163ED29E3D | 20:16 |
| thorst | so yep | 20:16 |
| thorst | that is the VM's mac, not the trunk | 20:16 |
| seroyer | Ok. Logs would be good. Thanks. | 20:16 |
| thorst | added bonus - console now doesn't work on that LPAR | 20:16 |
| thorst | :-D | 20:17 |
| apearson | But the good news is your getting that all the way down to the core...so my code is working at least :P | 20:17 |
| seroyer | Bonus! | 20:17 |
| thorst | seroyer: it works on other partitions, just not that one now | 20:17 |
| thorst | it says "Isolation failed for 30000005 with -9001" | 20:17 |
| seroyer | Islolation should happen on DLPAR remove, I thought…. | 20:18 |
| apearson | thorst - so that seems to happen if you try and dlpar remove a virtual serial adapter while the console is active. Any chance people did manual stuff with that device instead of going through mkvterm/rmvterm ? | 20:18 |
| thorst | apearson: no. | 20:18 |
| thorst | well, I did a 'rmvterm' - but that's the manual thing | 20:19 |
