Cannot use vmrun to start a virtual machine on RedHat 6.5: Error: The operation was canceled.

I tried to start the virtual machine on my RedHat 6.5 instance (under AWS EC2): /usr/bin/vmrun -T ws start /path/to/myWindows.vmx nogui

I got the error: Error: The operation was canceled.

Here is what I have set up: I created an instance RedHat 6.5 64bit in AWS EC2. In that instance, I installed "VMware-Workstation-Full-11.0.0-2305329.x86_64.bundle". In Windows platform, I used VMWare Workstation 11 to create a VM, which was transferred to the RedHat6.5 64bit instance. Then, I ran the command and it failed. Could please point to me any problem in my steps?  Thanks a lot!!
