 My intended use-case was to mount a container image that lacks kernel,
 fstab and bootloader, not a full virtual machine. Thank you very much
 for the explanation. I will try different approaches. 
I'm working on this, see the two threads starting at:
https://www.redhat.com/archives/libguestfs/2016-February/msg00205.html
https://www.redhat.com/archives/libguestfs/2016-February/msg00207.html
Do your container images have things like:
- /etc/hosts
- /etc/services
?
Thanks,
