[Libvir] problem with virConnectClose in libvirt 0.1.5

After closing libvirt with virConnectClose, it's possible to open libvirt again in the same program with virConnectOpen but following operations on domains systematically fail. In example: conn = virConnectOpen(NULL); dom = virDomainLookupByID(conn, id); virDomainFree(dom); virConnectClose(conn); ... conn = virConnectOpen(NULL); dom = virDomainLookupByID(conn, id); ==> ERROR The second virDomainLookupByID call fails because of the do_connect() function in xend_internal.c source file. In this function, the connect() API returns ENOENT on the second virDomainLookupByID() call. ENOENT return code isn't documented in the man of connect API ! I suppose that some cleaning are missing when virConnectClose is called or in the opposite, too cleaning is done. Regards.
