"save" state means that the machine is still being saved. It looks
like there are some kind of trouble saving that VM. Can you check  in
the execution host that $VM_DIR/<vmid>/images/checkpoint is created
and it is bigger than a few Kb's?

Supend saves the state of a VM to disk so it can be started again in
the same execution host. Stop is similar to suspend but moves the
state to the frontend node so it can be resumed in other execution
host. Cancel destroys the machine.

After the machine is successfully stopped or suspended you can
"resume" them. Shutdown and canceled VMs can not be restarted.
