Fixed In Version: vdsm-4.13.2-0.14.el6ev
Doc Type: Bug Fix
Doc Text:
Previously, migration of virtual machines between hypervisors would fail under certain conditions, causing the virtual machine being migrated to crash. This was caused by the logic used to clean up sockets for virtual machines after VDSM restarted due to an unexpected failure. Now, the logic used to clean up sockets for virtual machines has been revised so that VDSM correctly cleans up sockets after VDSM is restarted, allowing virtual machines to migrate without issue.
