03:02:55 swp20 hi Yumeng
03:03:57 Yumeng hi wenping
03:07:14 xinranwang Hi all
03:07:21 Yumeng hi xinranwang
03:07:23 swp20 the question about un-hotplug GPU is because the image is not available for cirros, when i use centos, it's ok for re-hotplug.
03:07:30 swp20 hi xinranwang
03:08:44 Yumeng swp20: what's the question?
03:09:06 swp20 i asked you on wechat
03:09:35 swp20 un-hotplug not success with qemu driver in use.
03:09:36 Yumeng let's start the meeting first :)
03:09:37 Yumeng #startmeeting openstack-cyborg
03:09:38 openstack Meeting started Thu Nov 26 03:09:37 2020 UTC and is due to finish in 60 minutes. The chair is Yumeng. Information about MeetBot at http://wiki.debian.org/MeetBot.

03:10:30 Yumeng #topic Agenda
03:11:18 Yumeng # topic vgpu
03:11:41 Yumeng #topic vgpu
03:13:33 Yumeng swp20: pls continue
03:14:00 Yumeng are you saying the detach failure in hotplug is because of cirros mssing?
03:14:36 swp20 yeah, the cirros vm process crash when detach the gpu device
03:15:06 swp20 the un-hotplug is not real success in fact.
03:15:58 swp20 cirros image is not support and centos is well.
03:18:13 Yumeng so vgpu hotplug is not supported in cirros but supported in centos, right?
03:18:51 swp20 i am not sure.
03:18:58 swp20 i means re-hotplug
03:19:27 Yumeng ok
03:19:43 Yumeng did you find out why un-hotplug is not successful?
03:19:59 swp20 attach, detach and reattach
03:20:19 swp20 i search the vm log
03:21:12 swp20 there is process crash problem.
03:23:01 Yumeng is it a occasional case or it crash every time?
03:23:41 swp20 it's high probability
03:23:51 Yumeng ok
03:24:32 Yumeng Has this crash ever happend in Centos?
03:25:10 swp20 hasn't met yet.
03:25:25 Yumeng ok. got taht.
03:25:46 swp20 cool
03:26:08 Yumeng looks like hotplug is image sensitive.
03:26:32 Yumeng Thanks wenping for the sharing
03:26:33 swp20 maybe the driver is important.
03:27:09 Yumeng do you mean nvidia virtualization driver?
03:27:37 swp20 no, i means the driver in image
03:28:03 swp20 gpu is not support well for cirros
03:28:14 swp20 include vgpu
03:28:39 swp20 you can test for vgpu about detach by 'virsh detach-device'
03:29:30 Yumeng yes, the VFIO mdev driver is very important. nvidia virtualization driver version must be well match the image version
03:29:48 Yumeng ok. will try when I got time
03:30:01 swp20 cool
03:30:13 Yumeng I also have a vGPU issue to discuss with you
03:30:20 Yumeng about the vGPU support
03:30:26 swp20 yep
03:30:58 swp20 i think in the time of bind arq is better
03:31:03 swp20 to create mdev
03:31:42 swp20 attach_handle is too early
03:32:20 swp20 and maintain task is heavy
03:32:20 Yumeng yes, I also think so.
03:33:58 swp20 so let's confirm this.
03:34:07 Yumeng xinranwang what do you think?
03:35:29 Yumeng Sylvain prefer create mdev in generate attach_handle. sean and gibi is fine with either
03:36:14 Yumeng from my perspective, I also prefer creating medv when arq bind
03:37:24 xinranwang if gpu's type is determined, the max number of vfs is also determined, right?
03:37:51 Yumeng yes
03:38:15 Yumeng but if it is changed, we need to delete all the created ones and create new ones
03:38:19 xinranwang if we do not create mdev at attach_handle generation step, how many vfs should we report?
03:38:26 Yumeng even if they were never used.
03:40:11 Yumeng xinranwang: the maximum number
03:40:36 Yumeng in the inventory, we always report the maximum number
03:40:43 xinranwang ok, got it.
03:41:39 xinranwang it seems create mdev during binding is more efficient. we just create it when we use it.
