03:05:01	Yumeng	we don't have many topics for today. just some schedule things about PTG
03:05:10	Yumeng	from my side.
03:05:29	Yumeng	Does anybody want to bring up anything else?
03:06:10	brinzhang	some patch need to +2 or +W
03:07:45	songwenping__	pls +2 and +W for my patch https://review.opendev.org/#/c/723865/
03:08:36	songwenping__	this patch
03:08:36	songwenping__	add ut for get arqs list
03:08:36	songwenping__	about five use cases
03:10:02	brinzhang	and this https://review.opendev.org/#/c/723783/, to update docs building
03:11:10	brinzhang	anyone around? I think we can quickly and go continue, right?
03:11:23	Yumeng	ok. tiny changes or urgent bug fix are ok to merge for now.
03:11:39	Yumeng	But let other patches hold on and PTG things first, right?
03:12:19	brinzhang	not all patches need take to PTG, I think
03:13:02	brinzhang	but such as QAT, FPGA, SSD driver, maybe we should read these spec firstly
03:13:25	Yumeng	Yes, new drivers necessary
03:13:33	Yumeng	please take a look https://etherpad.opendev.org/p/cyborg-victoria-goals
03:13:56	xinranwang	yes please review qat driver spec as well
03:14:39	brinzhang	I will add enable launchpad to the etherpad as a topic
03:14:52	Yumeng	I added new drivers spec in the etherpad so that we can disscuss
03:16:04	Yumeng	And added a topic schedule in the etherpad , which is to show what topics will be discussed on which day
03:17:07	Yumeng	not sure if all of you will attend all the meetings, so please add your name and indicate the time you will attend . If the topic schedule does not match your time, just update there or ping me
03:18:08	Sundar	The PTG time is very late for me. If you can schedule Cyborg-Nova-Neutron part in the first hour, I can join for that hour.
03:18:52	s_shogo	ok, thanks for good coordination, Yumeng
03:19:03	Yumeng	Sundar, Cyborg - Neutron - Nova Cross Project Session
03:19:48	Yumeng	Is this a good time for you. This room is booked by nova and shared with us.
03:20:01	Sundar	Oh it is June 5 1400 UTC i.e. 7 am for me. That's fine.
03:20:39	Yumeng	ok. that's great. So we don't need to change it.
03:21:27	Sundar	What IRC channel should I join?
03:21:47	Yumeng	Thanks s_shogo! So schedule things are done.
03:22:13	Yumeng	Sundar, it's zoom link instead of IRC
03:22:45	Sundar	Could you add the zoom link here , or in the etherpad?
03:22:59	Yumeng	I didn't get zoom room URL from community, I will add them to etherpad once I got them
03:23:13	Yumeng	Sundar,yes sure/
03:23:40	Sundar	Thanks, Yumeng
03:23:56	Yumeng	My pleasure.^^
03:24:19	Yumeng	So if nothing else, we've done today's meeting.
03:24:56	Yumeng	#topic AoB
03:25:44	Yumeng	Just one more check, nothing else wants to bring up, right?
03:26:28	Yumeng	Seems yes. So let's wrap up this meeting and I'll see you next week at PTG.

#openstack-cyborg - 2020-06-02
06:08:26	Sundar	Hello all
06:08:46	Yumeng	hello
06:08:57	brinzhang	Sundar means add two nova APIs to support bind and unbinding ARQs?
06:09:09	songwenping_	Hello all
06:09:11	chenke	Hi I move here.
06:09:17	brinzhang	hello all
06:10:05	Sundar	brinzhang -- That is not clear to me. If we can do HTTP PATCH on the server object, we can apply or remove devic eprofiles.
06:10:14	Sundar	SO I think it is one API only
06:10:56	brinzhang	Yeah, one or two all ok for me
06:11:22	Sundar	Second problem is with libvirt/qemu -- I don;t think we can add PCI interfaces to a running VM. We have to stop it first, regenerate the doain XML and then restart the server
06:11:38	Sundar	*domain XML
06:12:50	Sundar	What is the openstack CLI command you are thinking of?
06:13:24	Sundar	One option is to avoid all this, and just do a resize with a different flavor, which has a different device profile
06:13:31	Sundar	Then no need to change Nova API at all
06:13:39	songwenping_	Sundar, I have test the case of add and remove PCI interfaces to a running VM like this https://review.opendev.org/#/c/729945/5/nova/virt/libvirt/driver.py
06:14:51	Sundar	songwenping_ : How does this work? How will libvirt change the domain XML on the fly?
06:14:52	brinzhang	Sundar, I mean I want add two nova api to support binding and unbinding arqs from nova. that we can use "nova bind-accelerators and/or unbind-accelerators"
06:15:44	brinzhang	this need a spec to nova team
06:16:12	Sundar	brinzhang: The Nova CLI is old. In the new openstack CLI, we say: $ openstack server create --flavor myflavor ..., where myflavor has the device profile. What is the openstack CLI you plan to use for hot attach/detach?
06:17:02	songwenping_	`guest.detach_device(hostdevPCI, persistent=True, live=True)' this function with "live=True" param can work for running VM.
06:17:33	songwenping_	we can dumpxml the VM and see the hostdev PCI attach.
06:17:37	brinzhang	Sundar, they are same, we should do completed the cli in novaclinet and then to openstackclient to support, otherwise we cannt completed this feature in Nova
06:18:26	brinzhang	Sundar: binding/unbinding will be an independent operation in nova
06:19:09	brinzhang	Now we dont consider to support resize operation, that will be out of my control
06:19:19	brinzhang	I think
06:19:53	Sundar	brinzhang: will you pass a device profile to this CLI? if so, will one VM have 2 or more associated device profiles?
06:21:58	brinzhang	Sundar: maybe you are right, but I am sure I can answer your question, I dont know does it need pass device_profile to the CLI
06:22:14	Sundar	songwenping_: Great. I found this: https://libvirt.org/pci-hotplug.html Thanks for the pointer.
06:23:15	brinzhang	If we want to bind an ARQ to an instance that its flavor has not accel:device_profile, maybe we should pass it.
06:24:34	brinzhang	with unbind, I think we should judge the instance does have the accel:device_profile, access unbind or reject.
06:25:07	songwenping_	Yeah, right Sundar. Libvirt has supported hotplug for PCI devices.
06:25:41	Sundar	IMHO, it is better to support resize: it covers hot-add and is more generally useful also. It allows us to keep the model that one VM has one device profile.
