Prompt [This virtual machine seems to be in use], the virtual machine can not open the problem to solve

when the virtual machine is running, an abnormal shutdown. Causes the virtual machine to have the following error: This virtual machine appears to be in use. If this virtual machine is already in use, press the “Cancel” button to avoid damaging it. If this virtual machine is not in use, press the “&"""" button to get ownership of it. Configuration file: D: Virtual MachinesCentOS-6.3CentOS-6.3.vmx but click to take ownership, and error: the ownership of the virtual machine failed. The virtual machine is being used by a program on your host. Configuration file: D: Virtual MachinesCentOS-6.3CentOS-6.3.vmx later a mess of toss, suddenly thought of whether it is a problem with the *.lck folder, because I have encountered similar problems before. (See VMware:Failed to lock main memory file “Windows Server 2003.vmem”) So I did not endlessly, directly deleted the *.lck folder under D:Virtual MachinesCentOS-6.3, and then reopened in the virtual machine. D: Virtual MachinesCentOS-6.3CentOS-6.3.vmx. Oh, it’s normal. Tip: If you are afraid of problems, you can first move the *.lck folder under D:Virtual MachinesCentOS-6.3 to another directory, do not delete it directly.
