Every attempt to create a second virtual destkop with the same user on RedHat 9 ends with a black screen error or just returns to the connection dialog.

The problem occurs when the same user has a physical or virtual session already running.

A possible workaround is to install the following package on RedHat by using:

    $ dnf install dbus-x11
    
or change the value of the following key in node.cfg to:

DefaultDesktopCommand "/bin/dbus-run-session gnome-session --session=gnome"
