Xen devel - Dec 2005 - Xen3: Hiding PCI hardware from Dom0 and use it in DomX?

Hi,


I''ve been playing with the beta versions of Xen 3, and followed this 
list, but after release of the
official 3.0 release, I can''t find any info if the
''physdev_dom0_hide''
feature which was available
in 2.0.x is now also available in 3.0.
In the stable 3.0 documentation it is completely absent which leads me 
to believe that it is not
possible (as it was unavailable in the development tree for some time 
already), but in the
documentation nowhere is described that it has been removed (compared to 
stable 2.0.x).
Perhaps someone can shed some light on the status of this feature?

The reason I''m asking is because I''m currently using the
feature to
dedicate an ISDN card
to a specific domain, and am planning to do the same with a PVR card to 
create a MythTV
domain.
Also I would like to do more experiments trying to get X to run with 
dedicated hardware
in a second domain, and for that I need to give it access to my second 
graphics card.


Warm regards,
Mark.

Expect this functionality to get added back in in a point release early 
in the new year. It''s being worked on.

Is VMX domain support included?
Because I want to use an graphics card and SCSI HBA and Fibre Channel  
HBA from VMX Domain .

No. Running real physical device drivers in unmodified OSes will 
require further hardware support.
