#openstack-nova - 2020-11-11
15:21:51 sean-k-mooney that is why its there
15:21:55 sean-k-mooney the quick resume
15:22:03 dansmith the compute only gets the resources back on offload, but once you're shelved they could do that whenever they want,
15:22:15 dansmith so it's basically cache at that point
15:22:43 dansmith the client doesn't know when (or if ever) the offload will happen, so charging them more for some indeterminite period of time, and then cutting them down to cheaper on offload doesn't make any sense
15:23:13 sean-k-mooney i guess that makes some sense
15:23:56 sean-k-mooney it proably depend on the provider but i can see reducing at shelve too instead of shelve offloaded
15:24:22 sean-k-mooney anywya i think this is jsut an interop issue with the api
15:24:47 sean-k-mooney you cant really know what will happen when you call shelve i guess
15:25:06 dansmith that, and.. the only reason a user calls shelve is to save money
15:25:16 dansmith they have no idea when their resources will actually be freed,
15:25:40 dansmith they just know that they're saying "I'm telling you I won't need this for a while in exchange for some money back"
15:25:57 dansmith whether anything really happens immediately or later is not really their concern,
15:26:30 dansmith and they're not going to shelve it in order to pay more now, in hopes that they'll be charged less later when offload happens
15:26:31 dansmith it's not an investment :)
15:26:36 sean-k-mooney ya i guess when i use it locall its so i can back dev vms for feature x but i want to make capastiy for me to reuse
15:26:46 dansmith right, because you're on both sides of the curtain
15:27:01 sean-k-mooney ya
15:28:17 sean-k-mooney i guess its fine as it is
15:28:54 sean-k-mooney if i reset my expectation that the end state of shelve is one of (shelved, shelve_offloaded, error)
15:29:38 sean-k-mooney alot of our func test assume shleve_offloaded although that is fine since we can set teh config value if it matters in that test
15:30:10 gibi sean-k-mooney: a tangential question. Does nova support ports without IP allocation? I see https://review.opendev.org/#/c/669411 never merged, but I'm not sure we did other things to support it
15:30:32 gibi and I tried creating a neutron port with --no-fixed-ip
15:30:34 sean-k-mooney gibi: no
15:30:47 sean-k-mooney as far as i am aware we never enabled it
15:31:08 gibi yeah, I see Port 6370c969-73ca-41df-8c15-d91f10d44a59 requires a FixedIP in order to be used. (HTTP 400) with --no-fixed-ip ports
15:31:53 sean-k-mooney some of the concerns is that security groups and some qos policies may now work correctly
15:32:07 sean-k-mooney also the metadata api woudl not work
15:33:11 sean-k-mooney for l3 only backend like callico you also would have no network connectivty as you cant fall back to l2 in that case
15:33:40 gibi so I guess this cannot be added to nova generally, we have to somehow special case it if we need it
15:34:00 sean-k-mooney we now have the connectivity in the port
15:34:12 sean-k-mooney it will be either legacy l2 or l3 i belive
15:34:24 sean-k-mooney so we could allow it for l2 ports and maybe legacy
15:34:32 sean-k-mooney legacy was for backend that did not say
15:34:39 sean-k-mooney but your milage would vary
15:34:52 gibi thanks
15:35:18 sean-k-mooney actully rodolfos patch already has that https://review.opendev.org/#/c/669411/1/nova/network/neutronv2/api.py
15:36:33 gibi so that handles the l3 only backend case, what can we do with secgroups?
15:37:04 sean-k-mooney am well secgroups almost always deals with l3+
15:37:20 sean-k-mooney so if you have no ip then you can only use the ethertype rule
15:37:32 sean-k-mooney neutron will still do mac spoofing protection
15:37:41 sean-k-mooney i dont think we need to care about that
15:37:56 sean-k-mooney well we can care we just dont need to do anything
15:38:16 gibi OK, so we could repropos rodolfo's patch if we want
15:38:27 sean-k-mooney yep i have no issue with doing that
15:38:35 sean-k-mooney ie proceedign with it
15:38:46 sean-k-mooney he already did the neutron feature
15:38:53 sean-k-mooney which is what it was waiting on really
15:39:02 sean-k-mooney https://review.opendev.org/#/c/645645/
15:39:52 sean-k-mooney now that ovn is in tree we might want to make sure that reporst the attibute as l2 but other then that i dont see a blocker here
15:41:09 sean-k-mooney i think its kind of expected that if you have an adressless port that you cant use things like floating ips which neutron should block for us
15:41:11 gibi sean-k-mooney: thanks. I might repropose that at some point as it seem there is downstream need for it
15:41:48 sean-k-mooney we had a downstream request too at one point but it was obviously not a high priorit since its still pending
15:42:46 sean-k-mooney ovn is also updated fyi https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/drivers/ovn/mech_driver/mech_driver.py#L171
15:43:02 sean-k-mooney so it looks like everything is in place on the neutron side
15:43:28 gibi coolio
15:43:43 gibi I still not get the priority info hence the conditional from my side too
15:43:49 gibi let see
15:44:14 zigo sean-k-mooney: It IS included, it's just done in openstack-pkg-tools automatically.
15:45:08 zigo Also, nova-compute.conf only contains a few hypervisor specifics for switching virtualization depending on which nova-compute-FOO you install.
15:45:33 zigo ie: nova-compute-qemu will install qemu as virt driver, nova-compute-kvm will do kvm, etc.
15:45:40 zigo But everything else is in nova.conf ...
15:52:31 sean-k-mooney zigo: ya i saw they were minimal
15:52:51 sean-k-mooney so ideally you would do one of two things move the db and api db config into there own files
15:53:25 sean-k-mooney or move all compute node relevent options into the compute one
15:55:31 sean-k-mooney zigo: as they currently are you cannot use the auto rpc version since rocky
15:56:24 sean-k-mooney i.e. this https://github.com/openstack/nova/blob/master/nova/conf/upgrade_levels.py#L56-L57

08:07:18 f0o Hi, not sure if this is an issue in nova/kvm or the guest-os: Sometimes (really random) when a linux guest, predominantly CoreOS/Flatcar, attempts to reboot the instance is placed into Puased state instead. However the pause state is erroneously because there's no resume action possible so something must've gone bonkers in the state sync. Only issueing Hard-Reboot via cli will actually
08:07:20 f0o bring the guest back alive
