Moving data reception of the perform phase of migration to a thread introduces a race with the finish phase, where checking if the domain is active races with the thread finishing the perform phase. The race is easily solved by acquiring a job in the finish phase, which must wait for the perform phase job to complete. While wrapping the finish phase in a job, noticed the virDomainObj was being unlocked in a callee - libxlDomainMigrationFinish. Move the unlocking to libxlDomainMigrateFinish3Params, where the lock is acquired. Signed-off-by: Jim Fehlig <jfehlig@suse.com>
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.
