"instances.lxcfs.per_instance=true" not working

Incus
1

Hello,
after running:

incus config set instances.lxcfs.per_instance=true

all containers fail to restart.
I tried to restart 2 containers, both of them give the same error.

Here is the restart output and the relevant log:

[root@HOST ~]# incus restart MYCONTAINER
Error: Failed to run: /usr/libexec/incus/incusd forkstart MYCONTAINER /var/lib/incus/containers /run/incus/MYCONTAINER/lxc.conf: exit status 1
Try `incus info --show-log MYCONTAINER` for more info

[root@HOST ~]# incus info --show-log MYCONTAINER

By making lxcfs.per_instance=false again (the default), the containers were started without an error.

This is incus 6.6 on Fedora 40 (package version “6.6-0.1.fc40”).

Thank you.
Any ideas?

Thank you.

What’s the version of LXCFS?

Other than that, it’d be useful to do incus config set MYCONTAINER raw.lxc=lxc.log.level=trace then start the container again and provide:

  • /run/incus/MYCONTAINER/lxc.conf
  • /var/log/incus/MYCONTAINER/lxc.log
4 
[root@HOST ~]# lxcfs --version
"6.0.2"
[root@HOST ~]# dnf list installed|grep lxcfs
lxcfs.x86_64                                   6.0.2-1.fc40                       @updates

Sending you the two files after start failure on trace log level (/run/incus/MYCONTAINER/lxc.conf and /var/log/incus/MYCONTAINER/lxc.log) as a private message because of their contents.

Thank you.
