As discussed here [0][1] Coverity reported two issues: - On libxlDomainMigrationPrepareTunnel3 @@mig will be leaked on failures after sucessfull call libxlDomainMigrationPrepareAny hence we free it. Setting mig = NULL after @mig is assigned plus adding libxlMigrationCookieFree on error paths addresses the issue. In case virThreadCreate fails, unref of args frees the cookie on dispose function (libxlMigrationDstArgsDispose) - On libxlMigrationStartTunnel @tc would be leaked. Fixed by correctly saving the newly allocated @tc onto @tnl such that libxlMigrationStopTunnel would free it up.

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.
