11:00:21 openstackgerrit garyk proposed openstack/nova master: Resource tracker: remove costly copy https://review.openstack.org/576099
11:17:16 cdent efried: I have a question for you about powervm plans. Have you explored theoretical upper limits on number of instances in/on a compute node? In vmware-land we've discovered there are some inefficiences in the way data is managed in the resource tracker that can present some problems.
11:29:01 stephenfin gibi: Done and done
11:29:09 gibi stephenfin: thanks and thanks :)

12:45:27 gibi sahid: +W
12:46:02 sahid gibi: thanks
12:46:10 gibi sahid: thank you for the cleanup
12:59:30 efried cdent: I'm sure the PowerVC guys have some idea about that. edmondsw? (The question was: "Have you explored theoretical upper limits on number of instances in/on a compute node? In vmware-land we've discovered there are some inefficiences in the way data is managed in the resource tracker that can present some problems.")
13:00:25 cdent the latest is that there are some deepcopy of self.stats happening which may not be required
13:02:49 efried cdent: You're talking about the n-cpu service choking at a certain number of VMs?
13:03:17 cdent efried: exhibiting less than ideal load at >N VMs
13:03:25 cdent sometimes choking
13:06:07 edmondsw efried cdent we support a max of 1000 VMs per compute node
13:06:09 efried cdent: Sounds like something you may want to ask CERN about.
13:06:20 efried edmondsw: Is that a Power limit or an OpenStack limit?
13:06:26 edmondsw that's a PowerVC statement
13:06:52 edmondsw I'm not sure all of what went into picking that number
13:07:01 efried okay, so really just "nothing has broken down at this point, and we don't want to commit to testing more than that, and what do you think you need more than that for anyway??"
13:07:43 cdent efried: what does cern have to do with this, don't they kvm? (where the hardware presents physical limits. The issue for vmware is that it is possible to have a lot of hardware in one vcenter (which is tied to one compute node)
13:07:55 cdent it's not the recommend form to have a lot of nodes in one vcenter, but people do
13:08:21 cdent problems seem to start showing up around 1500 instances (whatever the hardware) on one compute node
13:08:22 edmondsw cdent I was wondering how someone would ever get up to a high number of VMs in x86 land :)
13:08:22 efried cdent: ohh, I see. We don't have more than one hardware node per n-cpu. But our hardware nodes can be big and hold a lot of VMs.
13:09:56 edmondsw efried cdent maybe ask the Z guys?
13:09:57 efried cdent: In that sense, the only difference with kvm is that we're hosting the VMs on the hardware, not within the controller VM.
13:10:06 efried yeah, I was wondering about z.
13:10:21 efried Pretty sure they also only use one hardware node, but not sure how many VMs they can handle.
13:10:28 edmondsw a lot
13:10:29 cdent the limits show up when the count of instances goes high, so it sounds like it would impact you guys too
13:10:34 efried I was kinda thinking they would typically have biggish VMs, but no reason to think that.
13:10:56 cdent things like syncing power state info
13:11:00 efried cdent: Well, it sounds like we cut you off at 1000 from a support statement standpoint, so...
13:11:22 efried I guess as soon as someone demands more, we'll see.
13:11:30 cdent are you interested in/excited by/disturbed by making that limit higher?
13:11:35 cdent jinxish
13:11:58 cdent it appears that going higher is relatively straightfoward. the limits are basically of the "oh we didn't think of that" variety
13:15:21 efried cdent: Oh, is there some hardcoded limit somewhere? I was getting the impression it was more of an overload.
13:19:53 edmondsw efried cdent I am told that PowerVC chose 1000 because PowerVM itself only supports 1000 per node
13:20:11 efried okay, fair enough.

13:33:33 mriedem alex_xu: is https://review.openstack.org/#/c/560317/ ready for a runway slot?
13:35:46 cdent efried: no, no hardcoded limit (that I'm aware of).
