In libxlDomainMigrationPrepare() if the uri_in is false, then 'hostname' is allocated and used "generically" in the routine, but not freed. Conversely, if uri_in is true, then a uri is allocated and hostname is set to the uri->hostname value and likewise generically used. At function exit, hostname wasn't free'd in the !uri_in path, so that was added. To just make it clearer on usage the else path became the call to virURIFree() although I suppose technically it didn't have to since it would be a call using (NULL)
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.
