09:55:24 mdbooth stephenfin sean-k-mooney: ^^^
10:00:13 mdbooth sean-k-mooney: The bottom of that stack is the new test base we discussed, btw, which also has a +1 from zuul. It would be useful to do the rounds on that one sooner rather than later. If you could rebase your patch on top of it so we can show it's useful that would be even better.
10:02:16 sean-k-mooney ya i can do that
10:40:19 ygk_12345 hi all
10:41:13 ygk_12345 I am going thru the nova code on github. Van anyone point me to the exact code which says the libvirt to use qemu-kvm binary to launch a new process for the vm ?
10:41:21 ygk_12345 *Can anyone
10:41:43 openstackgerrit Merged openstack/nova master: Add support for 'initenv' elements https://review.opendev.org/667975

10:47:10 openstackgerrit Surya Seetharaman proposed openstack/nova master: Include removal of ephemeral backing files in the image cache manager https://review.opendev.org/689422
11:17:15 artom ygk_12345, you mean you want to see a os.exec('qemu') in the code? You won't find it
11:17:29 artom ygk_12345, that's in the libvirt code itself
11:17:40 artom ygk_12345, Nova just defines a domain with some XML
11:17:40 ygk_12345 @artom where exactly ?
11:17:55 artom ygk_12345, I dunno, use grep, or ask in #libvirt
11:18:01 artom But mostly grep
11:18:25 cdent "But mostly grep" is my mantra
11:18:43 ygk_12345 @artom I have installed libvirt-python and used recursive grep but could not find the qemu-kvm pattern
11:18:49 artom Mostly Grep is my rap name
11:19:06 cdent oh, that's a good one
11:19:07 artom ygk_12345, that's because those are just the Python bindings for libvirt
11:19:22 artom ygk_12345, you want libvirtd
11:21:21 artom We form wht Unix Krew with Oh Snap it's Sed, Aw man it's Awk, and Who Let Perl In?
11:21:26 artom *the Unix
11:24:31 ygk_12345 @artom things at the OS level are weird but interesting
11:26:09 cdent ygk_12345: out of curiosity, why are you looking for the exec call? are you trying to solve a problem, exploring, something else?
11:27:07 ygk_12345 @cdent I am trying to understand and trace the vm create event through nova code :)
11:27:36 cdent I think what artom said is the key bit: nova creates some xml and gives it to libvirt, libvirt does the rest
11:28:25 ygk_12345 @cdent so its libvirt API internally
11:28:57 ygk_12345 @cdent awesome
11:29:28 ygk_12345 @cdent u see no limits to curiosity until we hit the hardware
11:29:37 cdent :)
11:29:57 cdent plenty of room for curiosity on the hardware too
11:30:45 ygk_12345 @cdent appreciate Linus Torvalds for his first version of Linux
12:17:24 ygk_12345 HI all ?
12:17:26 ygk_12345 which wsgi framework is used in nova ?
12:19:42 sean-k-mooney we kind of have our own https://github.com/openstack/nova/blob/master/nova/api/wsgi.py
12:19:56 ygk_12345 ok
12:20:32 ygk_12345 does it have a standalone web server ?
12:20:46 sean-k-mooney it can run in several different modes
12:21:06 sean-k-mooney it can run on the built in python webserver with eventlets
12:21:27 sean-k-mooney or you can run the wsgi service via mod_wsgi or uwsgi
12:21:58 ygk_12345 as of now when we install nova-api, in which mode deso it erun ?
12:22:04 ygk_12345 *does it
12:22:21 sean-k-mooney the nova api console script uses https://github.com/openstack/nova/blob/master/nova/cmd/api.py
12:22:26 sean-k-mooney which uses eventlet
12:22:27 sean-k-mooney but
12:22:31 sean-k-mooney if you use devstack
12:22:36 sean-k-mooney or most installers
12:22:44 sean-k-mooney the nova-api service is not calling that script
12:22:58 sean-k-mooney its running the service under uwsgi i think
12:23:05 ygk_12345 oh
12:25:18 sean-k-mooney ygk_12345: cdent know more about this then i but we moved to testing with extrenal wsgi server implemenation a few release ago
12:25:43 ygk_12345 oh ok
13:42:28 KeithMnemonic mriedem Good day, what is the best was to get some reviews on the patch you submitted for me ? https://review.opendev.org/#/c/683008/
13:43:29 mriedem KeithMnemonic: umm
13:43:45 mriedem you know we won't release that right?
13:43:58 mriedem since pike is in extended maintenance mode. we can merge stuff to pike but it won't be released.
13:44:08 mriedem so if you really need it you could probably just cherry pick it downstream
13:46:36 KeithMnemonic ok, i can do that, i was hoping it would get merged at least , is that not an option anymore even it if it is not released
13:47:13 mriedem it could be merged upstream but finding people to care about pike at this point upstream is hard, and that patch isn't exactly trivial
13:47:16 mriedem with all of the conflicts
13:48:16 KeithMnemonic ok let me try and cherry pick it locally
13:48:16 dansmith mriedem: api patch landed, can you kick this in? https://review.opendev.org/#/c/687141/
13:49:42 mriedem dansmith: were you going to reply to andrey again before doing so?
13:50:16 mriedem he is a core so i feel sort of bad if i just overrule him without a reply
13:51:03 dansmith okay
13:54:16 mdbooth Oh, that's evil
13:54:52 mdbooth In python2, if your module is in nova.tests.functional and you 'import fixtures', you get nova.tests.functional.fixtures. In python3 you get 'fixtures'.
13:55:13 mdbooth Apart from renaming nova.tests.functional.fixtures, I'm not immediately sure wtf to do about that.
13:57:55 mdbooth Fun fact 2: emojis in review comments elicit a 500 from gerrit.
13:58:01 sean-k-mooney mdbooth: that to do with relitive imports and what happens if you have a module in the local director that alisas a module in your path
13:58:23 mdbooth sean-k-mooney: Any idea how to disable in py2 in a manner which doesn't break py3?
13:58:50 sean-k-mooney there might be a futre thing for this. absolute import or something like htat
13:59:21 melwitt KeithMnemonic, mriedem: I started reviewing that patch yesterday but not done yet. it's taking forever bc of all the conflicts. I'll finish reviewing today
13:59:36 KeithMnemonic thanks!
