dispvms saving its sessions?

[pandak...@gmail.com]

I just saw that in the directory containing my default dvm (/var/lib/qubes/appvms/whonix-ws-ws-dvm/) contains alot of files named like this:
disp1.conf
disp2.conf
disp3.conf
And it keeps going on for a while, but I cannot seem to discover where they are coming from, since creating new and restarting the dvms does not solve it.
Is this normal behavior, or is this some weird configuration issue?

It is normal behaviour - if you don't change the dispVM then I think all
those files will be identical. If you switch around netvm etc then they
will differ according to allocated IP. If you upgrade dispVMTemplate
then they will differ by kernel version.

I use disposableVMs a lot and they tend to build up so I cull them by
hand now and then.
Probably not intended but harmless, I think.
