OK this is fantastic. Removing the package and clearing the cached appliances worked! Note to self: avoid using the cert-forensics-tools repository on servers running kvm. Thanks so much for your help. On 5/26/20 3:24 AM, Richard W.M. Jones wrote:

I'm not sure of the history of the server's libpcap install. Too many chefs and only one pot. I know, that doesn't help. Your question did prompt me to check versions and discover that there's a 1.9.0 version in the BaseOS repo. I removed the previous package and loaded the new one.
a quick ldd test ~]# ldd /usr/lib/systemd/systemd | grep libpcap libpcap.so.1 => /lib64/libpcap.so.1 (0x00007fc395a38000) This looks fine.
Also, looking at the libpcap-and-rebuild-testing.txt you provided previously, it looked like there is a package, pfring, that installs libpcap in /usr/local/lib:
supermin: rpm: multiple providers: requirement libpcap.so.1()(64bit): providers: libpcap pfring supermin: rpm: multiple providers: picked pfring
At least according to a quick search, it seems that this is the case: https://centos.pkgs.org/7/forensics-x86_64/pfring-7.6.0-2990.x86_64.rpm.html This is... bad: a package that: - installs a library in /usr/local - may override a system-critical library - even RPM-provides the system library (!) And omits the /usr/local/lib/libpcap.so.1 symlink from the file list.
I think it would work if only it included this file, although still be a bad, bad package for all the other reasons.
Rich.
This is a scholar example of things that can go wrong when packaging local stuff :-/
Do you still have that package installed? Can you please try by temporarly removing it?
but when I ran virt-sysprep it complains about libpcap again: "systemd-tmpfiles: error while loading shared libraries: libpcap.so.1: cannot open shared object file: No such file or directory" Try to clean the cached libguestfs appliance before, using $ rm -rf /var/tmp/.guestfs-$(id -u)
