[Xen-users] PCIe switch that does not support or enable ACS

[dongle <m.wessler@xxxxxx>]

Hi Folks:

I am oot able to add HP Intel 4Port PCIe to a linux hvm domain. HW is a HP
DC7900.

ErrorMessage:
VmError: pci: to avoid potential security issue, 0000:22:00.0 is not allowed
to be assigned to guest since it is behind PCIe switch that does not support
or enable ACS.

I also added in /etc/xen/xend-config.sxp:

pci-passthrough-strict-check no
pci-dev-assign-strict-check no

but no success.

Same HW Configuration works without any changes under xen 3.2.1 !

Thanks for your help !

Regards,
   Maik
