virt-sysprep : error while loading shared libraries: libcap.so.2

When I use virt-sysprep, I saw the following errors.

guestfsd: error while loading shared libraries: libcap.so.2: cannot open shared object file: No such file or directory

In my case, after upgrading an appliance of guestfs with “update-guestfs-appliance” command, I could solve this error.

Here are trial and error logs I did.

KVM host: Ubuntu 13.10

virtual machine: CentOS 6.5

update appliance.

# update-guestfs-appliance

run libuestfs-test-tool again.

Okay.

run virt-sysprep. okay.
