[Libguestfs] guestfs-examples

Hi, I tried to run the guestfs-examples from http://libguestfs.org/guestfs-examples.3.html, but they gave the following warnings and errors- #warning: Unable to get device geometry for /var/tmp/guestfs.JVxEUn/root #libguestfs: error: guestfs_launch failed, see earlier error messages What I did from the beginning- I boot my debian linux (2.6.32-5-686) inside VirtualBox and then install following packages there- #apt-get install qemu libguestfs-dev libguestfs-tools Then I created an image and install debian using qemu (inside my linux in VirtualBox, i.e. host)- #qemu-img create -f qcow2 deb.img 4G #qemu -m 256 -hda deb.img -cdrom debian-6.0.7-i386-netinst.iso -boot d Then I ran the vm using qemu in one terminal (inside my linux in VirtualBox, i.e. host)- #qemu -m 256 -hda deb.img -boot d In another terminal, I did- #gcc -Wall inspect_vm.c -o prog -lguestfs (without any warnings) #./prog deb.img Then the above warnings and errors were generated. Also I shutdown the vm, and tried to inspect the offline VM image (./prog deb.img), but it gaves the error- #libguestfs: error: guestfs_launch failed, see earlier error messages I tried to run the "EXAMPLE: DISPLAY THE OPERATING SYSTEM ICON OF A GUEST", but it gaves the same error- #libguestfs: error: guestfs_launch failed, see earlier error messages What is the problem here? Thank you. Best regards, Wahid
