@Tristis-Oris just FYI I fixed all of those issues you had, also regarding portable stuff - I implemented CLI switch -c <path> where you can specify directory where you want to store config, so you can wrap the app in a .bat or .sh script that would start it to use local storage (like flash drive) for config files, that should achieve portability.
If you expected something more sophisticated let me know
vm boots with no issues after retying migration with Windows 10 template.
Maybe there can be checks put in place to not apply vtpm with bios is selected? Going forward will make sure to select the current os for the template not a newer version.
@olivierlambert so strange though. i have it enabled on 4 pools, that didn't propagte on hosts.
still VM boots up when not needed as explained on fist post of the thread.
i'll try différent combinations to see what's really going on
