On Debian-based distros, the 'coredumpctl' command is
provided by the systemd-coredump package, which is not
installed by default. On failure, when "post" commands
are executed this error is seen:
controller | /bin/bash: line 1: coredumpctl: command not found
Install it along with other libvirt packages to avoid
the error.
On Fedora distros it is in the systemd package, so the
problem is not seen since it is always installed.
