Very hard to know what's going on based on the data you're giving. Do you use the management module? What do the journals say about the transport error? Seems as though the container volume files are not loading or not recognized, in what format did you have them and are they on a mounted volume that can be found by the system, and does the system have access rights ("storage" group perms?)
Im not doing anything advanced. its just a standalone exsi server that runs vm's. After looking at the logs and stuff I found out that it was Unlocker. If you uninstaller it fixes itself next boot.
