Fedora is migrating away from: /etc/sysconfig/network (the HOSTNAME=... setting) /etc/sysconfig/keyboard /etc/sysconfig/i18n to: /etc/hostname /etc/vconsole.conf /etc/locale.conf See the tracker bug 881785 for details. We found in libvirt-sandbox-0.1.0/bin/virt-sandbox-service: NETWORK_CONFIG = "/etc/sysconfig/network" ... fd=open(self.dest + self.NETWORK_CONFIG, "w") fd.write("HOSTNAME=%s\n" % self.config.get_name() ) Please update the package for the new config files.
The current release uses /etc/hostname.
