How to migrate an OS X guest VM to a physical machine? I am running OS X Yosemite, and Parallels 10.

I have a guest VM running OS X Yosemite. I would like to migrate the guest VM to a physical machine. Is this possible? The reason is that the guest vm is just too slow, and I would be better off running on a physical machine. I have a number of developer tools installed and configured perfectly on the VM that would take a long time to download them on the physical machine. Thats why I just want to "migrate" to a physical machine.

I tried connecting an external hard drive to the VM, and creating a time machine backup, but it fails to even make the initial backup. The error message is:

"An error occurred while copying files. The problem may be temporary. If the problem persists use disk utility to repair your backup disk"
Use SuperDuper or Carbon Copy Cloner to create a bootable image
to an external or internal disk. SuperDuper can also be used for free.
