Virtualization: guest 10.5 in 10.8.2 host - how?

Question

macOS

There is a need to run PPC code on a new Mac Pro that comes with 10.8 out of the box. Updated to 10.8.2, decided to extract the 10.5 Server installation disk from the bins, because Parallels Desktop and Fusion manufacturers only allow virtualization of server versions 10.5/10.6. Installed Parallels Desktop 8, created a virtual machine. Specified the path to the disk. The car starts and immediately turns off. PDM7 behaves the same way. Fusion 5 and 4 pretend to start, and then the download stops.
I tried discs from torrents, the same situation with them. I decided to check it on an iMac, then on a MacBook Pro 15 "retina - the same behavior.
Actually, the question is - did anyone manage to run a guest 10.5 Server? If so, how?

Answer 1

There are instructions for installing 10.6 in Parallels. It is possible that it will help you.
