If you are wanting to get your Parallels VM off of your MAC and into QVS, open Windows in Parallels and download and install XenConvert.

Run XenConvert and select from your WinVer to OVF and make sure you have enough space on your Virtual Disk to save the file. Copy the OVF from the Win-VM to the NAS. Open QVS and the OVF will then import directly into QVS as a new VM.
If your running fusion, even easier. Just select your vmwarevm file and select the vmx file and import.
Both methods tested successfully with both Win7Ultx64 and Win8.1x64 importing into Virtualization Station on a TS-451 running 4.1.1 with 4GB RAM.
