The xenXMConfigCacheRefresh method scans /etc/xen and loads all config files it finds. It then scans its internal hash table and purges any (previously) loaded config files whose refresh timestamp does not match the timestamp recorded at the start of xenXMConfigCacheRefresh(). There is unfortunately a subtle flaw in this, because if loading the config files takes longer than 1 second, some of the config files will have a refresh timestamp that is 1 or more seconds different (newer) than is checked for. So we immediately purge a bunch of valid config files we just loaded. To avoid this flaw, we must pass the timestamp we record at the start of xenXMConfigCacheRefresh() into the xenXMConfigCacheAddFile() method, instead of letting the latter call time(NULL) again.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
