01:49:43 Spazmotic Yeah it's totes hush hush, just letting you openstack fellows know.. DON'T TELL TRUMP
01:50:14 mriedem he'd actually be in bed eating by now if it weren't for some speech he has to give tonight
01:51:17 Spazmotic I'd imagine he's still doing that thing
01:51:25 Spazmotic Just speech from bed with giant slippers

09:18:18 Spazmotic Morning
09:36:13 Spazmotic Last day of my weekend.. then just 4 days and work and finally 2 weeks in KOrea to relax
09:44:23 Spazmotic Going to take the rest of the day off and avoid python.. have a good night all, will be afk :)
09:50:36 openstackgerrit blkart proposed openstack/nova-specs master: don't show description content in code-block https://review.openstack.org/539478
09:54:11 bauzas jianghuaw: not sure you saw https://review.openstack.org/#/c/539266/2
10:01:40 jianghuaw bauzas, yes. I saw it. Just have not got chance to check it due to having been occupied by a kolla deployment problem.
10:01:44 jianghuaw thanks for asking, surely will look at it before I leave office.
10:01:52 openstackgerrit Rajesh Tailor proposed openstack/nova master: Allow force-delete even if task_state is not None https://review.openstack.org/530879
10:04:33 bauzas jianghuaw: ideally, you could make a follow-up with the Xen notes
10:05:14 jianghuaw Sure.
10:31:09 amotoki hi, i have a question on 'host' parameters in os-aggregates and os-migrateLive API.
10:31:21 amotoki I am working on https://review.openstack.org/#/c/538472/ (in horizon).
10:32:02 amotoki in nova API there are two types of "host". the one is from os-services and the other is from os-hypervisors.
10:33:49 amotoki I checked the API reference but I am still not clear which is expected for "hosts" in os-aggregates and "host" in migrateLive (and migrate) action.
10:34:06 amotoki thanks in advance.
10:35:42 bauzas amotoki: it refers to the os-services hostname
10:36:02 amotoki bauzas: thanks. is it true for both?
10:36:26 bauzas amotoki: well, there is a confusion
10:37:09 bauzas amotoki: long story short, hypervisors provide their own hostnames, so we have a tuple (service hostname, hypervisor hostname) identifying a single node
10:37:28 bauzas for most of our virt drivers, a compute service only serves a single hypervisor
10:37:44 bauzas so there is no real problem in adressing the host itself by its service name
10:37:56 bauzas but for ironic, that paradigm isn't true
10:38:18 bauzas since a single compute service serves for all the ironic nodes
10:38:24 amotoki i think the same thing happens for vmware (vcenter) driver.
10:38:28 bauzas no
10:38:41 bauzas because nova sees the vCloud as a single node
10:39:00 bauzas how it's managed within that cloud is beyond its view
10:39:04 amotoki does nova consider vCloud as a big host?
10:39:08 bauzas exactly
10:39:19 bauzas from a scheduling perspective
10:39:34 bauzas which is what aggregates are for :)
10:41:34 amotoki aggregates refer to service host name, so how can we distinguish individual hosts? is it determined based on aggregate metadata?
10:42:43 ameeda Hello, what is the different between "self.volume_api.detach" and " self._detach_volumes" in nova manager ?
10:45:08 bauzas amotoki: sorry, was at the coffee machine
10:45:24 amotoki bauzas: no problem. thanks for your support
10:46:55 bauzas amotoki: so, the answer is "that's not supported"
10:47:17 bauzas amotoki: all the Aggregate API logic is based on services checks
10:47:53 bauzas amotoki: that means that if you use ironic and want aggregates, you will only shard your cloud by the compute services, that's it, not by your ironic deployment
10:48:04 bauzas call it a limitation
10:48:54 bauzas from my perspective, it's just that ironic introduced a new paradigm (N hypervisors for a single service) without changing the Nova API, which is why it's broken
10:49:14 openstackgerrit Yikun Jiang (Kero) proposed openstack/nova master: Encode libvirt domain XML in UTF-8 https://review.openstack.org/522161
10:50:29 amotoki bauzas: thanks for clarification. I see the current logic and it is good to know that :)
10:51:24 openstackgerrit Stephen Finucane proposed openstack/nova master: trivial: Fix typos in release notes https://review.openstack.org/539490
10:59:26 jianghuaw bauzas, thanks for creating the documents for vGPU. The patch looks very good. I will add the part for XenAPI.
11:00:13 bauzas jianghuaw: FWIW, I'm also currently working on providing a functional testcase that will use a fake libvirt driver with mdevs
11:00:56 jianghuaw bauzas, thanks for the heads-up.
11:01:25 jianghuaw What's I can help on that>
11:02:01 bauzas there are a couple of libvirt functional tests already, so I'll land that funct test battery into there
11:02:14 bauzas you could see if Xen got some
11:02:40 jianghuaw ok. will check it.
11:02:42 bauzas later, we could discuss with other folks if we would maybe have a single test battery that would check both drivers, I dunno yet
11:03:33 bauzas like a base test class that would test what's supported by both drivers, and we would just inherit from it
11:03:45 bauzas of course, the setup of that test class would be per-driver
11:03:59 jianghuaw sounds good.
11:04:05 bauzas jianghuaw: so, nothing from your side yet I guess
11:04:25 jianghuaw ok.
11:04:31 bauzas just maybe if you have time, try to see how to mock your Xen API the less invasive way
11:05:17 jianghuaw k
11:05:22 bauzas ideally, I wouldn't want to mock every single libvirt call like we do in the unittests, rather just pass a libvirt fixture that would setup my host like I want
11:05:34 bauzas hence the fakelibvirt module reading
