 hexa | I hot-added CPU cores to a VM … wow 😄 | 09:39:08 |
| hexa | htop shows them as offlien thought, so I wonder if our nixos image is missing anything | 09:39:19 |
| hexa | oofff | 10:11:50 |

| hexa | wow | 10:14:59 |

| hexa | but the VM is actually up | 10:15:35 |
| hexa | and was migrated to incus2 | 10:15:56 |
| hexa | 🫠 | 10:15:58 |
 adamcstephens | Yeah we may be missing CPU hotplug | 11:02:30 |
| hexa | I'll file an issue for that as well | 11:15:42 |
| adamcstephens | I suspect that one is on our end | 11:25:17 |
| hexa | Yep | 11:35:11 |
| adamcstephens | Probably an easy one to add a test for too :) | 12:31:05 |
| hexa | SUBSYSTEM=="cpu", ACTION=="add", TEST=="online", ATTR{online}=="0", ATTR{online}="1"
| 15:11:39 |
| adamcstephens | ahh so just a udev rule | 15:27:40 |
| adamcstephens | does memory hot add work or do we need something similar? | 15:27:51 |
| hexa | that works | 15:32:17 |
| hexa | 4GB -> 2GB -> 4GB tested | 15:32:25 |
| adamcstephens | cool | 15:32:29 |
| adamcstephens | so this is just CPU, and just for VMs? | 15:32:37 |
| adamcstephens | i'm done grading now so i can actually just test it myself :) | 15:32:57 |
| hexa | yes | 15:33:13 |
| hexa | opened an issue | 15:33:18 |
| hexa | referenced what suse is doing | 15:33:22 |
| adamcstephens | cool, thanks | 15:33:27 |
| hexa | took their rule and dropped the x86_64 constraint | 15:33:35 |
| adamcstephens | In reply to @hexa:lossy.network
took their rule and dropped the x86_64 constraint what is the "upstream" you speak of here? | 16:13:08 |
| hexa | possibly incus agent? | 16:13:30 |
| hexa | also we should rebrand our stuff | 16:14:34 |
