A script to open your favorite terminal as root it's for minimal template users but should work for "full" template users i don't like to type in dom0 "qvm-run -u root" then the name of the vm it's annoying you can misstype the name and typing again is annoying.

  1. The script will ask you which vm you want to open as root
  2. You don't even have to type the full name of the vm let's say ur vm as for name "xxxxxxxxxxxxxxxxx" the script will automatically find the vm and log in as root for you.
  3. In case there is multiples match the script will ask you which one you want to pick. Example you have multiple disp open you just type "disp" then he will show you every match he find for "disp"
  4. You can click on the vm you want or click on "ok"
  5. I included popular terminal in the script but if your terminal is missing you can add it yourself (or i could edit the post and add more) i don't know which one is better
