[Xen-users] Driver Domains

[Andrej Radonic <andrej.radonic@xxxxxxxx>]

Hi,

I am wondering whether the mechanism of "driver domains" or "backend 
domains" is currently supported in Xen 3.02.
Maybe someone can shed some substantial light on this.

I derive that there is some concept like any domU can be a backend 
domain for block or network devices from the fact only that both "xm 
network-attach" and "xm block-attach" support the "backend" parameter 
(at least according to the current man page). Also some mail authors in 
this list have used "netif=1" and "blkif=1" to define a domU as backend 
domain.
When I try to put this in to practice, though, I - and apparaently 
others as well - get turned down with a "device could not be connected, 
hotplug scripts not working".
What I do is this:

1.) in the "serving" domain:
netif=1 (also tried netif = 'yes')
name=serveit

2.) for the "receiving" domain
network-attach <domid> backend=serveit

or

1.) in the "serving" domain:
blkif=1 (also tried blkif = 'yes')
name=serveit

2.) for the "receiving" domain
block-attach <domid> file:/var/image/myimage.disk hda2 r serveit

Any ideas?

Thx a lot. Cheers,
Andrej
