Wheezy iso cd image not booting?

[Josef Wetzel <jwetzel@hispeed.ch>]

Hi all

I am trying to install Debian wheezy in VMWare Fusion 4.1.2 on Mac OS X 
10.7.4.
I downloaded debian-testing-amd64-netinst.iso (on 13. may 12) and 
configured Fusion to use this iso image as a cd drive.
When I power up the virtual machine, a blinking cursor in the upper left 
corner of the screen is showing up and nothing else happens.
When I do the same thing with debian-6.0.4-amd64-netinst.iso (squeeze), 
the installer comes up and everything works as expected.
(btw I burned a cd from the wheezy iso image and tried it in a Dell 
desktop, with the same result: nothing happens.)

What am I doing the wrong way?

Thanks for any help

Josef
