I’ve been struggling with this forever now, and I still have yet to find a way to do it. Either one of two things need to happen.
1) Convert my existing VirtualBox vbox/vhd to be used on Parallels 7
2) Install Windows 7 + IE vhd from MS into Parallels 7 on Mac. (http://www.microsoft.com/en-us/download/details.aspx?id=11575)
I have tried converting my VirtualBox instance to an OVA, then from an OVA to VMX – didn’t work. I’ve also tried using Parallels built in converting tool through command line – also didn’t work.
It might be best if you have Parallels to try this, because speculation or reading on Stackoverflow probably won’t help me.
