| 11:20:22 | sean-k-mooney | its configurable and we overried it downstream | |
| 11:20:39 | sean-k-mooney | kashyap: have qemu reduced the memroy overhead | |
| 11:20:50 | kashyap | sean-k-mooney: I know it is. | |
| 11:20:57 | kashyap | sean-k-mooney: The memory overhead is negligible, BTW | |
| 11:21:04 | sean-k-mooney | it was not in the past | |
| 11:21:54 | sean-k-mooney | danpb did a lot of testing and it was a signifcant increase | |
| 11:22:08 | kashyap | sean-k-mooney: I know that whole thing, I also referred to it in the commit message | |
| 11:22:39 | kashyap | See my comment on _why_ the overhead is acceptable in the commit message | |
| 11:23:18 | sean-k-mooney | its more the 16mb | |
| 11:24:00 | kashyap | Sigh, where are you quoting that from? I recall putting up that WIP after extensive discussion with the virt folks | |
| 11:24:21 | sean-k-mooney | On memory usage of using Q35 machine type with different number of root | |
| 11:24:23 | sean-k-mooney | ports: | |
| 11:24:25 | sean-k-mooney | - Q35 with 4 root ports: the "resident RAM" is 2056 MB | |
| 11:24:27 | sean-k-mooney | - Q35 with 32 root ports: the "resident RAM" is 2066 MB | |
| 11:24:29 | sean-k-mooney | The additional overhead of increasing the number of root ports is just | |
| 11:24:31 | sean-k-mooney | about 16 MB. This is acceptable. | |
| 11:24:39 | sean-k-mooney | but the comparisons i remeber were showign more then that | |
| 11:25:45 | kashyap | Well, I quoted DanPB's stats there | |
| 11:26:17 | sean-k-mooney | i guess if you are already using q35 its only 16mb | |
| 11:26:32 | sean-k-mooney | what we were orgianlly concered about was the increase form pc to q35 | |
| 11:26:40 | sean-k-mooney | so if we keep the default as pc | |
| 11:26:57 | sean-k-mooney | then i guess we could but based on your arm triles | |
| 11:27:07 | sean-k-mooney | im not sure we shoudl do it vai the config option | |
| 11:27:21 | sean-k-mooney | or perhaps we shoudl set it to say -1 | |
| 11:27:23 | kashyap | Hmm, our upstream default is still 'pc', right? | |
| 11:27:34 | sean-k-mooney | meaning nova use the most that we know works for the acitrues | |
| 11:27:42 | sean-k-mooney | kashyap: yes it is | |
| 11:27:54 | kashyap | Okay, I need to think a bit more about this; now /me really steps out :) | |
| 11:28:07 | sean-k-mooney | https://review.opendev.org/c/openstack/nova/+/663614/1/nova/conf/libvirt.py | |
| 11:28:29 | sean-k-mooney | thats the comment that makes me thing we woudl be better allowing -1 to mean nova chooes the larges value that will work for the arch | |
| 11:28:56 | sean-k-mooney | so 32 on x86 and 24 on aarch64 | |
| 11:29:21 | sean-k-mooney | and delegate to libvirt for anythign we dont have a known good value for | |
| 11:29:27 | sean-k-mooney | same as 0 today | |
| 11:30:07 | sean-k-mooney | if we did something like that i can proably be sold on updating the value | |

| 12:43:49 | kashyap | sean-k-mooney: Yeah, arch-specific setting makes sense | |
| 12:47:04 | Uggla | question, I have this signature: def _hard_reboot(self, context, instance, network_info, block_device_info=None, accel_info=None, share_info=None): I would like share_info to be an ShareMappingList object either empty or with items (not None). Shoud I change to share_info=ShareMappingList(), an empty list by default. I noticed the file is also under mypy so I could define a type. What is your preference ? | |
| 12:49:24 | sean-k-mooney | Uggla: no never | |
| 12:49:33 | opendevreview | Christian Rohmann proposed openstack/nova master: db: Drop redundant indeces on instances and console_auth_tokens tables https://review.opendev.org/c/openstack/nova/+/856757 | |
| 12:49:55 | sean-k-mooney | Uggla: you shoudl never us a collection as the default for a keyward arg | |
| 12:50:34 | sean-k-mooney | Uggla: the way python works is that the vlaue of the keyword args are initalised once one the fucntion is first parsed and then rused across all function calls | |
| 12:50:54 | sean-k-mooney | so fi you default to a list or object that object will be shared across all fucntion calls | |
| 12:51:23 | sean-k-mooney | so kwargs shoudl only be litral values like Ture 42 None | |
| 12:51:30 | opendevreview | Christian Rohmann proposed openstack/nova master: db: Drop redundant indexes on instances and console_auth_tokens tables https://review.opendev.org/c/openstack/nova/+/856757 | |
| 12:51:32 | sean-k-mooney | "a sting litral" | |
| 12:51:49 | sean-k-mooney | so share_info=ShareMappingList() is not correct to use | |
| 12:52:51 | Uggla | ok, but what is the good way to be sure share_info will have the proper type and safely call its methods ? | |
| 12:53:08 | sean-k-mooney | we can add the type annotations | |
| 12:53:23 | sean-k-mooney | but its if you want ti to be a requried arge then it should not be a kwarg | |
| 12:53:30 | sean-k-mooney | if its optional you should do | |
| 12:53:48 | sean-k-mooney | if share_info is None: | |
| 12:53:53 | sean-k-mooney | share_info=ShareMappingList() | |
| 12:54:08 | sean-k-mooney | in the hard reboot funtion if you need too | |
| 12:55:05 | sean-k-mooney | in most cases we woudl expect this to be None as most vms wont have shares | |
| 12:56:31 | Uggla | ok thx sean-k-mooney. | |

| 07:46:14 | Uggla | Good morning Nova. | |
| 07:51:51 | bauzas | good morning | |
| 07:52:00 | gibi | o/ | |
| 07:52:20 | gibi | Uggla: do you still have a question on my comment on the manila series ? | |
| 07:53:11 | Uggla | hi gibi , no that's ok for the moment. :) | |
| 07:53:30 | gibi | Uggla: cool. Sorry for not responding last week I was deep in some k8s discussions | |
| 07:54:03 | Uggla | gibi, no worries that's fine. | |
| 08:43:05 | sahid | o/ I have specific use-case regarding nova host-evacuate, we would like evacuate host to run but that, all instances scheduled to be forced as shutdown | |
| 08:43:18 | sahid | is there a way to have this happening? | |
| 08:48:13 | sean-k-mooney | no | |
| 08:48:38 | sean-k-mooney | evacuate at the api level result in the vm being evacuated to the same state its in in the db currently | |
| 08:48:46 | sean-k-mooney | so you would need an api change for that. | |
| 08:49:06 | sean-k-mooney | novaclient's shell is deprecated so we are not adding or alterign any commands | |
| 08:49:22 | sean-k-mooney | and nova host-evacuate is intentionally not supported in osc | |
| 08:49:36 | sean-k-mooney | so at this point we should not alter/extend its behavior | |
| 08:50:03 | gibi | I'm wondering what happens if you try to first stop the VM then evacuate it | |
| 08:53:27 | sahid | gibi if the host is down, nothing is happening | |
| 08:53:51 | sahid | the other idea was to extend resetState | |
| 08:54:43 | gibi | I feel like this might be a new microversion to the evacuate action, adding a flag to instruct nova to evacuate but not start the VM on the dest | |
| 08:56:22 | sahid | it's what I was thinking as-well but for host-evacuate it seems that you don't want we make any changes | |
| 08:56:56 | gibi | host-evacuate is a client side concept. You can replace that with a shell script calling the openstack client | |
| 08:57:37 | sahid | side question, why host-evacuate is not supported in openstack client? | |
