pvm may have been a simplification and an easy solution. We'd have to package a standard image as a pvm file and I don't think that will be that simple.
Parallels can boot into the ivanti preboot environment however our requirements are secureboot and uefi and there seems to be some kind of disconnect with parallels 14 and sorting that out. So at this current time I don't think there is much on the ivanti end that can resolve this issue.
