This means it isn't supposed to work, or this means you don't know about 
anyone trying to use those binaries besides me? :-)

I am willing to help all I can to test, but I'm not a Gnome developer. I 
have not coded a single line in C for more than 10 yeas. :-(

If you (or someone else) sends me testing or debuging binaries, I'll be 
glad to test them. I'll even setup another virtualization host if some 
thinks a newer CentOS, RHEL or Fedora could help. But I won't be able to 
code myself.

I hope someone at Red Hat gives attention to this, because most admins 
of a RHEL / RHEV host runs Windows desktops. My home computer runs only 
Fedora, but at work (most customers, anyway) I have to use Windows. :-(

C:>virsh -V
Virsh command line tool of libvirt 0.10.2

Do you know who built the Windows port? I know someone is doing that, 
because the binaries are updates every few months. :-)

Again, I'm willing to help any way I can, but I can be only a tester, 
and a documentation writer. I won't be able to help as a developer. :-(
