Never update Parallels and a kernel on the same day...

And, as I found out this morning, after updating to kernel 5.3.7: DONT delete the temp directory after you're done. For some reason the build doesn't get stashed in DKMS anymore, so every time you update a kernel, you have reboot into the kernel, Ctrl-Opt-F2 into a new screen, and run the installer manually again.
 
So, I went back in, removed the edits on those four lines and made the change to the script instead, forcing the define to 0. That's a much cleaner way to do it, personally.

1. Mount the ISO and copy the contents to a temp location
2. In the kmods directory there was a tar.gz file that you need to unpack (tar -xvzf)
3. Navigate to the unpacked file prl_vid/Video/Guest/Linux/kmod/test/test_drm_core.sh and change the PRL_DRM_VM_OPERATIONS_FAULT assignment to "=0"
4. Repack the directory using the tar command (tar -czvf name-of-archive.tar.gz /path/to/directory-or-file) replacing the old file.
5. Run installer again.

You might need to uninstall the old version too.. I know there is a KB article around somewhere that talks about manual removal.

I'll be on a mac a little later this morning if this doesn't work, post again, and I'll check to see what above needs to be updated.

That seems to have done the trick for me. Many Thanks.

Worked for me too! I was struggling a lot with this issue.. I really have to consider if Parallels is worth buying. Works so smoothly but not being able to install the tools makes a bad impression. Thanks a lot for these detailed instructions!
 
Except, I'm still finding that Parallels Tools is either not rebuilding or installing correctly when a new kernel is installed. I have to do it manually after a new kernel install then rebooting. The reboot sequence never gets to the graphical login screen.
