22:47:32	cburgess	I haven't been up there in almost a decade. Keep meaning to go one summer, I hear its amazing. Only been skiing in the winters.
22:48:06	mriedem	cburgess: you can't come some place
22:48:08	mriedem	geez
22:48:17	cburgess	Do what?
22:48:38	mriedem	nvm
22:48:57	melwitt	I know what it is and noticed it
22:48:58	clarkb	mriedem: I perpetually have the problem of tryingto explain wtf is going on during sportsball to everyone else around me. I have learned its extra bad when at live event
22:48:59	melwitt	hehehe
22:49:20	melwitt	cburgess: oh yeah, same here in that this was my first summer trip there. I didn't know what to expect but it was really fun. 13/10 would recommend
22:49:23	mriedem	clarkb: at least you have people around
22:49:51	clarkb	I had the twins signaling touchdowns on command last season though
22:49:56	clarkb	I think they need retraining this year
22:50:14	melwitt	mriedem and clarkb are gonna be likethis watching MNF
22:50:30	mriedem	i really should be mowing the lawn actually
22:50:37	mriedem	laura can hear me giggling from the kitchen
22:50:47	melwitt	o/ laura
22:51:14	mriedem	alright i'm going to go do that
22:52:12	clarkb	melwitt: and ya I've had to look for food options around ptg, trying to sort out infra team options
22:52:35	clarkb	melwitt: IHOP and buffalo wild wings are across the street
22:52:44	clarkb	be warned though IHOP does not serve alcohol
22:58:10	cburgess	Hmm there are 2 waffles houses but they are driving distance. (

08:57:01	rabel	so, vmware ci insists to fail on https://review.openstack.org/#/c/494169/ but imho the error has nothing to do with the patch set. it should be ready for final review / merging than, i guess.
08:59:29	cdent	rabel: vmware ci is borked, you can’t trust it at the moment, unfortunately
09:00:41	cdent	rabel: as long as your unit tests are fairly complete, should be okay
09:02:39	rabel	cdent: should be, yes.
09:08:41	cdent	gabor_antal: thanks for commenting on the complexity thing and including those references, especially to the test results, great to see
09:09:10	gabor_antal	cdent: you're welcome. Hope the community finds it interesting too
09:11:24	cdent	gabor_antal: I think there are plenty of people who find it interesting. The challenge is often finding the review bandwidth to get the stuff merged (as you’ve experienced).
09:12:36	gabor_antal	cdent: that is true, but we have also lots of patches, which are stuck, and just reopened now, maybe someone has an idea to move on.

13:58:10	efried	Who's an expert on PCI passthrough in nova? (The internals, not the ux)
13:58:26	stephenfin	efried: Nice work on https://review.openstack.org/#/c/493701/
13:58:48	efried	stephenfin Thanks :)
13:58:58	stephenfin	efried: I have a rough idea on it, but I'm not expert. moshele and sean-k-mooney know their stuff though
13:59:04	stephenfin	*no
14:00:29	efried	stephenfin Okay, at least for the sake of having a sounding board, here's what I'm trying to work with:
14:00:52	efried	On Power, our PCI devices don't have 32-bit domain:bus:slot.func PCI addresses.
14:01:24	efried	The nova PCI code around whitelisting, passthrough devices, and aliases is *all* set up to assume domain:bus:slot.func
14:02:11	efried	At the moment, if I want to make PCI passthrough work in PowerVM, I have to very carefully leave out any reference to addresses in the whitelist & alias specs.
14:02:25	openstackgerrit	sahid proposed openstack/nova master: libvirt: slowly live-migration to ensure network is ready https://review.openstack.org/497457
14:02:25	openstackgerrit	sahid proposed openstack/nova master: libvirt: add method to configure migration speed https://review.openstack.org/497456
14:02:26	openstackgerrit	sahid proposed openstack/nova master: libvirt: bandwidth param should be set in guest migrate https://review.openstack.org/497455
14:02:40	efried	And when I create my pci_passthrough_devices list (from get_available_resource), I have to spoof a domain:bus:slot.func PCI address for each dev.
14:02:52	efried	Cause each dev has to have a distinct address, or it won't get recognized at all.
14:03:02	efried	So this leads to a couple of problems.
14:03:30	efried	One is that I have to hack these addresses horribly. (And from a 64-bit source, so possibility of collisions, etc.)
14:04:04	efried	The other is that I've given my op the ability to whitelist device *classes* (vendor x prod ID) but not specific devices.
14:04:25	efried	Because as soon as I try to specify a device in the whitelist, nova tries to get at /sys/bus/.../<PCI address>/...
14:04:33	efried	...which isn't a thing in PowerVM.
14:05:18	efried	btw, I have reason to believe HyperV and VMWare (and maybe xen) suffer from a similar class of problem (the devs not being owned by the node running the compute process).
14:05:55	efried	So
14:06:40	stephenfin	HyperV too, for that matter. I don't know the specifics though
14:07:52	efried	One possible inroads may be the new resource provider stuff.
14:08:12	cdent	I was just going to say that nest providers will help with this, but it is a long road before it completely resolves it
14:08:55	efried	If my compute node registers a rp that provides the PCI devs as generic resources, they could conceivably have arbitrary names/identifiers.
14:09:17	efried	But we would have to replumb the whole whitelist concept if we wanted to support whitelist filtering.
14:10:44	efried	I would be happy to reimplement whitelisting in a way that works for PowerVM, but would have to have some way to bypass the whitelisting that nova's doing.
14:10:57	cdent	the long term goal (jaypipes can you confirm this?) would be to get rid of the on-node whitelist stuff
14:10:57	efried	[pci]whitelist_by_compute_driver = True
14:11:05	stephenfin	Yeah, the plan was to move most of the PCI device management code to resource providers
14:11:22	stephenfin	Any vGPU stuff would also be done this way
14:11:23	efried	Yeah, jaypipes and I talked briefly about that in Boston.
14:11:55	stephenfin	Hmm, so how do you define what devices can/can't be used if you don't have unique identifiers like that?
14:12:06	efried	oh, I have unique identifiers.
14:12:12	efried	They just don't look like domain:bus:slot.func
14:12:19	cdent	bigger better unique identifiers!
