MichelDwo You mean that you have performed a manual configuration or do you have a kind of automatic sync
Nothing that fancy. I install packages on the VM so that it matches (as close as possible) those that are installed on my daily-driver laptop (Plasma). The idea is to be able to use it comfortably for an extended period, without constantly doing mental translations, like "where is that on this system," or "what do I use instead of that when I'm here."
That includes modifying /etc/fstab to include NAS shares that are present on my laptop, and if I'm feeling productive, writing symlinks to replace /home folders with appropriate shares. Thus, /home/jerry/Downloads actually links to my NAS's Downloads/Linux share, so that browsers, for example, use it automatically.
If I really LIKE a distro, I spend more time with it, for example, configuring Thunderbird with multiple email accounts, a couple of address books, and a couple of Google calendars. And sync'ing Vivaldi, and installing LastPass, so I have full access to all the sites I use. Thus, I can order lunch to be delivered, log on to health portals when I get an email saying that a new message awaits me there, and so on.
The bottom line is such that I can fire up the VM (Solus Xfce, in this case), and use it at full-screen, and just about forget that I'm looking at a VM instead of my Plasma laptop, itself. I did that for three days with Xfce, and was very impressed.
