| 11:44:12 | sean-k-mooney | gibi: ill be reinstalling my home system later in the week so ill try and see if i can get something working at the weekend | |
| 11:45:31 | sean-k-mooney | im hoping i can just use kolla's supprot for deploying elk or efk technically to maintian the stack | |

| 11:46:10 | sean-k-mooney | what i need to figure out is what is the best way to upload the logs to it form the upstream jobs | |

| 11:49:02 | sean-k-mooney | im thinking of trying the http plugin for fluentd to submit the logs with basically curl. | |

| 12:19:11 | admin0 | hi guys .. is it possible to add bus and slot on pci_passthrough alias whitelist ? | |

| 12:19:41 | admin0 | if there is multiple network-cards or multiple pci cards or the same vendor and product-id , how do I differencitate it | |

| 12:22:57 | admin0 | in whitelist we can specify the bus slot and function .. but how to do it in alias ? | |

| 12:27:58 | admin0 | the use case is this ... say i have 4 devices, and i want to pick device 1 and 4 for vm1 and 2 and 3 for vm2 .. what happens is since i cannot pass the bus/slot on alias, it picks up device 1 and 2 for first vm and 3 and 4 for 2nd vm .. if its possible to pass the exact in alias somehow, it might solve that issue | |

| 12:31:36 | admin0 | you mean there is no feature for me to alias 4 specifc device of the same kind ? | |

| 12:32:34 | sean-k-mooney | you can have muplite device of the same type on the host but an alais can only be used to select a device of a given type not a specific one | |

| 12:33:12 | admin0 | sean-k-mooney, thanks ... so what possbility exits if I have multiple devices of the same type and I want to target specific ones ? | |

| 13:06:59 | sean-k-mooney | its not imposiable to do and we hope to do it eventually but its of similar complexity to cpu pinning | |
