As many other software vendors, Parallels Team is working hard on the required tweaks to make sure you can run Parallels Desktop virtual machines on macOS High Sierra, as well as install macOS High Sierra in a virtual machine.
If you intend to install macOS High Sierra preview on your Mac as a host OS and keep using Parallels Desktop for Mac, we strongly recommend you install the latest update of Parallels Desktop 12 for Mac version 12.2.1 (41615) - download link.
Here is the list of known issues we are working on with the available workaround that we have tested in our lab.
