[Fedora-xen] What's the Pre-requisites for virt-manager

[Henry Zhang]

hi Daniel,

 From the webpage, I can see that dbus and gnome-python-desktop are 
optional, but when our release engineer try to build, seems they are 
not, so could you confirm me if we can build/run virt-manager correctly 
without Dbus?

I carefully read the content in "Dbus Services", My understanding is 
that Dbus in virt-manager is used to make other external application 
call some core function, so that they can get display the window/dialog .

When Dbus is used?

"The remote control module provides the DBus service 
<http://virt-manager.et.redhat.com/dbusservice.html> allowing various UI 
functions to be controlled remotely.": My understanding for "remotely" 
is to run virt-manager remotely, is it correct? so will dbus only used 
when remotely? if some application in local machine, it may also use 
Dbus to run some function?


Thanks,
Henry
