By writing of this post, I just download the AX7 CTP8 Vm and configure on my machine.
I successfully configure it on hyper V. Only one tricky point is external network adapter in Hyper V.
First step is download VHD and extract it to some place. If you are registered to AX 7 Feedback program, then you must have vhd download link.
After the download, run the self-extract exe and extract the Vhd at specific location.
