Xen users - Mar 2007 - What does backend attribute in xm list -l signifies?

Hi,
The output of the command ''xm list -l'' gives something as :
(device
        (vif
            (backend 0)
            (script vif-bridge)
            (bridge xenbr1)
            (mac 00:16:3E:BD:8F:2E)
        )
    )
    (device (vbd (backend 0) (dev hdd:cdrom) (uname phy:/dev/dvd) (mode
r)))
    (device
        (vbd
            (backend 0)
            (dev hda:disk)....

Can you please explain what does this backend 0 signifies?
Does that mean that the backend is Domain0?
Thanks and regards
Ashit

Yes.  This is almost always the case, except where driver domains are in use 
in which case it may point to one of those.

Cheers,
