Expected behaviour you didn't see

If we requested the chassis type through dbus org.freedesktop.hostname1 in a VM, we expected the chassis type should be "vm" rather than an empty string ''.

Unexpected behaviour you saw

If we request the chassis type in qemu and virtual box, it always returns an empty string.

Steps to reproduce the problem

1. Install Fedora in a VM (QEMU or Virtual box)
2. Request chassis type through dbus interface "org.freedesktop.DBus.Properties"
3. the returned value should be an empty string.
