Please provide the full incus info output and also detail how Incus was installed and on what Linux distribution.

incus info: incus-info.txt

Incus was installed from source following the instructions in the "From source: Install" section of the "Install Incus" chapter.

Linux distro is Slackware current. I have modified the distro to use cgroups v2. [~]$ grep cgroup /proc/mounts cgroup2 /sys/fs/cgroup cgroup2 rw,nosuid,nodev,noexec,relatime,nsdelegate,memory_recursiveprot 0 0

Did you also install and run LXCFS?

[alex14641]

Running LXCFS fixed the issue. Thank you for your help. Note that security.syscalls.intercept.sysinfo doesn't seem to be needed.
