Problem access hardware with xen 3.0 unstable

Problem access hardware with xen 3.0 unstable

[Manuel Bernhardt]

Hi,

i've tried the last days xen 2.0 testing get working with my hardware 
(tv card) but the drivers together with xen won't work. Now i've 
installed an snapshot today from xen 3.0 on my maschine and can't access 
the hardware. If i insert the "pci=" key in my config file, i get this 
message:

Error: Exception: Error creating domain: (38, 'Function not implemented')

What goes wrong? PCI Support is enabled, i tested with and without ACPI, 
no success.
Have the configuration parameter changed? Have i overlook any part of 
the documentation?

We don't currently support pci devices outside dom0.

Also when i boot an domain with dom0 kernel instead domU kernel ?

I'm afraid so. We currently have no interface for unprivileged domains 
to access PCI space. If we gave a domU unfettered access to PCI space 
and BIOS tables there would be a big conflict betwene that domain and 
domain0.

This isn't going to be very hard to fix, but stabilisation and domU 
interface freezes come first.

It's ok so - i think stabilisation and domU interface freezes for 
production use in the industrie is a "little bit" more important like my 
problems which appears during "home use" of xen :-)
