Hi i think the process state and the memory state are not saved and when the vm is moved to the new host its listet as down. But it should resume the saved processes and memory.
yes, i have try this with a iscsi storage and when i move a running vm:
the runningng vm are saved
then the vm moved to the new server
storage are not moved (iscsi)
the vm resume the processes and memory and comes in the running state
so the vm are not shuttetdown or restartet, when i move a running vm the vm will be saved and resume after move. This process are faster as shutdown and startup.
The process are not working with a nfs storage, it hangs on point 4.
