Hi

Vm’s under containers set to auto start does not automatically start when rebooting 25.10

2

That’s not correct. At least not for me - my VM does start automatically - and probably most others as such a bug would’ve been noticed at least in beta if it was very widespread.

Could you elaborate more on what exactly happens? Have you looked into some log files?

3

ok, what logs would you check?

this is a vm that was created originally under virtual machines

4

In /var/log, more specifically in messages, error, middlewared.log but especially in /var/log/libvirt/qemu/<your-vm>.log

5

/var/log/libvirt/qemu/ is empty

already looked at messages,

yes i have escalated to root

Incus vms and lxc do not Autostart on 25.10

Damn I overlooked the “under containers” part of the initial question xD

That makes sense now.

@erlend_oyen can you migrate the VM back to classic virtual machines?

  1. the vm starts just fine under containers, when i start it manually
  2. the vm is still present under virtual machines (auto start not enabled)
    i never removed it from virtual machines, after it was auto migrated over to containers

You probably chose the linked clone option when asked how to migrate the VM disk.

This means the VM under virtual machines is probably still in the state before the migration and you’d need to basically merge the changes done to the clone back to the original (probably via promotion of the clone, then you can delete the original and clone the current state back to a new zvol).

hm, i don’t think so, but how can that be verified?

anyway it’s been working fine right upon til 25.10 i have been using the vm with autostart under containers for a while.

I do believe that @LarsR is right and Incus VMs/containers now just don’t autostart anymore. I would very much advise you not to you Incus VMs anymore as they won’t be supported in the future as it seems.

To verify if the zvol is a linked clone, check if it has a “promote” button under datasets or run zfs get origin <zvol> - if it has an origin (not just “-”) it is a linked clone.

I know that they don’t autostart anymore, but i can’t remember where it was mentioned anymore…
