AW: [Xen-users] Paramters for PCI passthrough in config file

It''s most likely that your PCI devices reside on the same PCI bridge.
When including
support for FLR, a requirement check was added to have all PCI devices that
reside on
one PCI bridge to be co-assiged to one DomU, although that''s not
necessary when the
DomU is PV.

You can check with lspci -tv whether this is the case and when you use pv
domains,
you might use this patch that will disable FLR and this kind of message.

BR,

Carsten.

Hi,
I was trying now since two weeks to pass pci cards to different domU''s.
First I used XEN 3.3, but there I got error messages like

must be co-assigned to the same guest , so I switched to other distris and
versions.

Now I have:

mainserver:/etc/xen# xm info

cc_compile_date        : Sat Jun 28 09:32:18 UTC 2008
xend_config_format     : 4

and run into the problem that I can pass only one pci to a DomU. I use the
following parameters in the /etc/xen/domU.cfg


pci         = [ ''11:00.0'',''11:09:0'' ]

I have tried different versions like
pci         = [ ''11:00.0'', ''11:09:0'' ] or
pci         = [ ''0000:11:00.0'',
''0000:11:09:0'' ] and so on.

The only solution is to pass these parameters with the command line, like:

server:/etc/xen# xm create DomU.cfg -c pci=''11:00.0''
pci=''11:09.0''

Then I get two PCI cards inside the DomU.

Does anyone know how to pass them correctly inside the config file.

Thanks

Hans

AW: AW: [Xen-users] Paramters for PCI passthrough in config file

Hi,

as I expected. Brooktree and Philips attached to the same bridge. If you are not
able to patch Xen before building it, I think you have to find a combination
that
comes out of the box.

BR,
Carsten.
