I just realized libguestfs uses fork. Now we know why qemu-img worked - I
launched it with popen.

If I understand the question correctly - it's about how

Re: guestfs_launch() fails when C application is started as a systemd service
Here are strace outputs per process.
strace_output.22076 is the plugin's pid. (A little before forking)
strace_output.22077 runs qemu-img
strace_output.22078 is a mystery to me
strace_output.22079 is rm -rf to the overlay image and its temporary dir.
Best Regards,
Peter

Re: guestfs_launch() fails when C application is started as a systemd service
Thank you, Rich,
This was the issue indeed. export LIBGUESTFS_BACKEND=direct fixed it.
The next step I tried was to integrate libguestfs in collectd virt plugin
to collect this data automatically.
In this case I'm having an unknown error in add_libvirt_dom() (same with
add_domain) when it's invoking qemu-img to create overlay image.
There is no difference between manual and service
