Did install from source of libguestfs-1.20.1 on Ubuntu-12.10. And libguestfs-test-tool complains about not finding libcap.so.2 uptime: 2.26 1.00 guestfsd: error while loading shared libraries: libcap.so.2: cannot open shared object file: No such file or directory [ 2.277795] Unregister pv shared memory for cpu 0 [ 2.278324] kvm: exiting hardware virtualization [ 2.278763] sd 2:0:1:0: [sdb] Synchronizing SCSI cache [ 2.284494] sd 2:0:0:0: [sda] Synchronizing SCSI cache [ 4.224797] Disabling non-boot CPUs ...

Should an install of libguestfs be considered as a "do at your own risk" endeavor? Putting it in the quasi-support realm? And is the appliance trying to find libcap.so on the host or within the appliance when it fails? Skippy
