If virDomainSaveConfig() failed, we will return NULL to source, and the vm is still available to restart during confirm() step in v3 protocol. So we should kill it off in qemuMigrationFinish(). In v2 protocol, we should not set vm to NULL, because we hold a reference of vm and should unrefernce it.
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.
