Our seclabel parsing was repeatedly assigning malloc'd data into a temporary variable, without first freeing the previous use. Among other leaks flagged by valgrind: ==9312== 8 bytes in 1 blocks are definitely lost in loss record 88 of 821 ==9312== at 0x4A0645D: malloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==9312== by 0x8C40369: strdup (strdup.c:42) ==9312== by 0x50EA799: virStrdup (virstring.c:676) ==9312== by 0x50FAEB9: virXPathString (virxml.c:90) ==9312== by 0x50FAF1E: virXPathStringLimit (virxml.c:112) ==9312== by 0x510F516: virSecurityLabelDefParseXML (domain_conf.c:4571) ==9312== by 0x510FB20: virSecurityLabelDefsParseXML (domain_conf.c:4720) While it was multiple problems, it looks like commit da78351 (thankfully unreleased) was to blame for all of them. * src/conf/domain_conf.c (virSecurityLabelDefParseXML): Plug leaks detected by valgrind.

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.
