What apps can run my windows virtual machine created by Parallels Desktop?

I just bought PD last weekend & needed their tech support to get Win ME up & running. However, it only runs in low rez with 16 colors & even they couldn’t help me with that. I was wondering if another emulator could do the job since I’ve already got a virtual machine that runs well. Many of these are free like Virtual box but it wouldn’t take a .pvm file. Any ideas?
