Lxd-to-incus results in VM not starting anymore

,
1

Hello

I just migrated from LXD to Incus this afternoon and faced several issues I’ve been able to tackle.
i.e: after migration none of the container went starting, I had to add the rule raw.lxc: lxc.apparmor.profile=unconfined in every container for them to start.

Now problem remains in VM in which I had docker installed previously in LXD.

Trying to start them results in :slight_smile:

# incus start az-coe-microsoft

Try `incus info --show-log az-coe-microsoft` for more info

Any idea ?

incus --version

6.0.3

Can you show the full incus info output as well as incus config show --expanded az-coe-microsoft?

That’s a rather unusual error which suggests something really weird is going on with the system this is running on (and could be linked to the apparmor issue you mentioned which is also not something we’ve really ever seen).

Sure

The container is privileged (security.privileged=true), do unprivileged containers behave better?

I’ve reboot the whole server as I said in another post and it’s behave better.
VM is now starting but facing an error when launching docker.

With LXD as a lot of issues using VMs, will migrate them to containers as it’s seems to work better with incus.
