Qubes does not delete all data about deleted qubes

Why does a lot of data remain after deleting qubes? I noticed that all my test deleted qubes can be found in sudo lvs. It creates a problem of disk space being filled

I also found files about deleted qubes in /home/user/.config/menus/applications-merged/. It seems very dangerous to create a qube with a suspicious name (darknet, hacking, etc.) - info about the creation of this qube will be retained in the system (as if it was left intentionally for forensic specialists).

Hi, I tried to replicate your command by using ‘sudo lvs’ in the dom0 terminal, but I wasn’t able to find any of the deleted qubes. I can only see the logical volumes corresponding to the current qubes I’m using.

For the files you found in /home/user/.config/menus/applications-merged/, I can also see the files related to my deleted qubes. However, after reviewing these files, it appears that they are used for setting up the “Qubes Application Menu.” They don’t contain sensitive data; rather, they only list the applications that you’ve included in the “Qubes Application Menu” for display.

Do you have a standard Qubes installation? Are you using a vm-pool?
