Finally I got Haiku run with Parallels 8. I found two important posts:
1. https://www.haiku-os.org/guides/virtualizing/parallels-desktop
2. https://www.haiku-os.org/community/forum/haiku_41_actually_works_parallels_7
I started with the first post and downloaded the actual Anyboot image on the Haiku website (step 1).
After that I used the three Terminal commands of the second post to convert the image to an hdd file.
Then I switched back to step 2 of the first post. I created a new virtual machine in Parallels from installation disc, continued without installation disc and selected as operation system more other > other. Then I stopped the virtual machine after the failed boot process. I opened the configuration panel and browsed in the hardware tab for the hdd file I created.
After that I could start the virtual machine! There is no need to disable the network adapter. Everything runs fine now!
