Rich, I know that you've stated in the past that you don't do 'install' and refer to the run scripts and the README file in response to problems installing libguestfs on Ubuntu.

Should an install of libguestfs be considered as a "do at your own risk" endeavor? Putting it in the quasi-support realm?

It should work, but it's not necessary, and it may have bad effects. It will pollute your filesystem with files which are not managed by dpkg (making them effectively impossible to remove). It will likely conflict in strange ways with the real libguestfs dpkg. The easier way is just to use the ./run script in the libguestfs directory, eg: ./run ./fish/guestfish [etc] Note that 'make quickcheck', 'make check' etc implicitly uses the ./run script.

And is the appliance trying to find libcap.so on the host or within the appliance when it fails?

The problem above is that libcap.so.2 isn't being copied into the appliance. There could be several reasons for this: (1) Most likely, what is installed on your host doesn't match what is listed in /etc/apt/sources.list; eg. libcap might have recently had an soname bump in Ubuntu and you haven't yet installed the new version on the host (but febootstrap picked up the new version for the appliance). Just doing an 'apt-get dist-upgrade' should fix it. (2) You're mixing the appliance from another installed libguestfs with the appliance from the libguestfs you built locally. This doesn't appear to be the case, from the full output you gave. (3) Did ./configure pick up that libcap is installed? Did it link guestfsd with -lcap? Did you then uninstall libcap on the host? Did febootstrap download libcap during the build? (4) There's some problem with the dpkg metadata. (5) There's some bug in febootstrap or the dpkg/apt utilities that it depends on. #4 and #5 can be diagnosed by carefully looking at whatever is being generated in '/usr/local/lib/guestfs/supermin.d/hostfiles', while at the same time reading this: http://libguestfs.org/febootstrap.8.html#supermin_appliances You can also avoid building the appliance at all by using the fixed appliance: http://libguestfs.org/download/binaries/appliance/ Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-df lists disk usage of guests without needing to install any software inside the virtual machine.
