if I connect to my server via ftp, I get logged into the ftp-root of my host! How can I target to my virtual machine instead (I had hoped ISPConfig would do that for me ;-) ?
I guess you logged in with the wrong username or your FTP doemon does not allo chrooting of users. If you use a user that has been created within ISPConfig, you will login to the home directory of this user. If the user has the "administrator" checkbox enabled, th home directory of this user is the root directory of the website the user belongs to.
