I've already tried the method described by webmatze some days ago with Parallels Desktop 9.0.24237.1028877 as well as 9.0.24229.991745 and it doesn't work. The created Installer-Image works, because VMware Fusion 6.04 and VirtualBox 4.3.14 can boot it, but Parallels 9 can't. It seems we have to buy Parallels Desktop version 10 .....
But no really luck for me with VMware Fusion 6.04 and VirtualBox 4.3.14: VMware cannot assign the required 2 GB RAM on my 2 GB machine (but Parallels can) - similar with VirtualBox, it starts anyway, but hangs completely (the whole Mac) after 20 percent of the Yosemite installation.
