Before we rewrote nss plugin so that it doesn't use libvirt's internal functions it used virLeaseReadCustomLeaseFile() to parse .status files. After the rewrite it's using read() + yajl_parse() + yajl_complete_parse(). There's one catch though, virLeaseReadCustomLeaseFile() skipped over empty files. An empty .status file is created when a network is started. This is because we configure dnsmasq to use our leasehelper. So the first thing it does it calls it as follows: DNSMASQ_INTERFACE=virbr0 /usr/libexec/libvirt_leaseshelper init which causes the leasehelper to create empty virbr0.status file. If there is only one libvirt network then that is no problem - there are no other .status files to parse anyway. But if there are two or more networks then the first empty .status file causes whole parsing process and subsequently the whole name lookup process to fail.
