 adamcstephens | oof | 16:22:17 |
| adamcstephens | did you ever get ovn working? | 16:25:48 |
 hexa | I got it clustering | 16:35:06 |
| hexa | but unless I have storage there is no reason to toy with networking | 16:35:17 |
| adamcstephens | right | 16:56:13 |

| hexa | ok | 12:11:18 |
| hexa | killed ipv4 on the ceph cluster, reoboted, tada | 12:11:24 |
| hexa | 
Download image.png | 12:13:57 |
| adamcstephens | so ipv4 was doing something weird? | 12:58:33 |
| hexa | 0.0.0.0 addresses in the osdmap, multiples actually | 13:00:43 |
| hexa | and that confused the kernel's libceph driver | 13:00:56 |

| 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 |

| 10:15:02 |
| 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 |
