19:18:53 Sundar How would a GPU device vendor support Power? Does he have to write a plugin/whatever for the hypervisor?
19:18:55 efried This is why pypowervm can't just "poke around the device" directly.
19:19:22 efried Somebody has to write drivers, yeah.
19:19:36 efried You're way out of my area of expertise here, though.
19:20:18 Sundar Hmmm, I need to think about this.
19:20:37 Sundar Would SR-IOV device flow differ from the above in any significant way?
19:20:38 efried I have no idea how e.g. FPGA programming is going to work. I'm only guessing it'll work like I mentioned above, where we'll have to attach the device to the management partition, where we'll have the right device driver installed, and we'll do the programming there, and then detach from the mgmt partition and attach to the VM.
19:21:12 efried So SR-IOV we actually have working today, just without placement in the picture; it's all hacked into the old PCI passthrough subsystem.
19:21:35 efried But SR-IOV is special (even more so) on power.
19:22:28 efried We virtualize the VF through the virtial I/O servers. (That's three virtuals in that sentence.) This allows us to do redundancy at the platform level (rather than aggregation at the VM) and it also enables live migration of SR-IOV VMs.
19:23:07 efried But - the discovery and plug steps are much the same in the sense that we do them by making REST calls.
19:23:34 efried It's just the nova flow that's totally different at the moment. I'm actually not sure how we're going to do SR-IOV with placement. Maybe just not, yet.
19:23:45 efried edmondsw: Have we considered ^ ?
19:24:22 Sundar Power's mgmt vs. hypervisor split sounds a bit like Xen's Dom 0 vs hypervisor split, except Xen drivers in dom0 can access devices directly (no REST API needed). Does that sound about right?
19:26:14 efried I'm afraid I don't know.
19:27:59 Sundar OK, let me process that a bit. Thanks, efried. I didn't think I would get a crash course in Power as part of Cyborg development. ;)
19:28:15 efried Sundar: Nobody expects the Spanish Inquisition.
19:28:35 efried And I'll thank you not to use "crash" and "Power" in the same sentence again.
19:28:41 efried Never happens.
19:28:54 Sundar haha, sure.
19:29:23 efried Thanks for the chat, Sundar. Keep up the good work, sir.
19:29:54 Sundar NP. Take care, efried.
19:56:10 edmondsw efried that's long... what were you asking?
19:56:59 efried edmondsw: What, if anything, our plan is for porting our SR-IOV support over to placement-land
19:57:55 edmondsw efried I thought you were considering that, but I have not spent time on it
19:59:02 efried edmondsw: I haven't really considered it yet, no. I think for the forseeable future if we continue to expose SR-IOV devices via PCI passthrough it will *probably* just work with the GPU-via-placement stuff.
19:59:13 efried But eventually we'll want to get it all into placement-land.
19:59:22 efried I just don't know what that's going to look like.
20:00:00 edmondsw I must be missing something. Hasn't SR-IOV been one of the example use cases in several conversations?
20:00:20 efried example use case of what, in conversations about what?
20:00:38 edmondsw placement, traits, resource providers, etc.
20:00:44 edmondsw nrp
20:00:49 efried I've talked a lot about SR-IOV in general, hypothetical terms when discussing those things, yes.
20:01:05 efried But we haven't ever gone into the specifics.

11:01:35 hyunsikyang Hello all
11:01:35 hyunsikyang I am Hyunsik Yang at Soongsil Unviersity, South Korea.
11:01:35 hyunsikyang In the OPNFV project, especially, infra WG, i am trying to provide vBaremetal environment for testing the OPNFV platform.
11:01:35 hyunsikyang For that, IPMI and PXE should be supported well like as a physical server.
11:01:35 hyunsikyang However, in the current OpenStack environment, NOVA manages the lifecycle of the VM, so IPMI operation based on KVM does not work normally.
11:01:36 hyunsikyang To support this, NOVA should support IPMI and PXE. Therefore, this proposal intends to add a function for normal control ofIPMI and PXE in NOVA.
11:01:36 hyunsikyang So, i uploaded spec first. If anyone who interested in this proposal, Please review it.
11:01:37 hyunsikyang Thanks.
11:01:37 hyunsikyang The link is below.
11:01:38 hyunsikyang https://review.openstack.org/#/c/577048/
11:03:52 lyarwood hyunsikyang: https://docs.openstack.org/tripleo-docs/latest/install/environments/virtualbmc.html - you might want to look at how TripleO already does this with the vbmc project
11:04:01 lyarwood hyunsikyang: https://github.com/openstack/virtualbmc
11:08:51 hyunsikyang I knew it. vBMC which is based on KVM is now working for openstack instance. so, we also make a code for it too.
11:16:42 hyunsikyang lyarwood: I knew it. vBMC which is based on KVM is now working for openstack instance. so, we also make a code for it too.
11:21:56 openstackgerrit Balazs Gibizer proposed openstack/nova master: Escalate UUID validation warning to error in test https://review.openstack.org/540386
11:22:55 lyarwood hyunsikyang: I don't follow, doesn't Ironic provide what you need?
11:26:48 hyunsikyang lyarwood: YES. Ironic used VM Which is based on KVM.
11:27:26 hyunsikyang lyarwood: I want to use openstack instance as a baremetal.
11:27:44 lyarwood hyunsikyang: then just use vbmc to provide the ipmi layer to Ironic?
11:27:58 lyarwood hyunsikyang: nova is never going to directly support ipmi or pxe
11:31:36 hyunsikyang lyarwood: i can't understand what is the meaning of 'then just use vbmc to provide the ipmi layer to Ironic?'
