[Xen-users] PCI passthrough on PV domU crashes with iommu=soft

Hello ,

Following the http://wiki.xen.org/xenwiki/XenPCIpassthrough doc.

I get several issues to perform pci passthrough

The config file is in Addendum 0

I'm using the debian XEN 4 and kernel 2.6.32-5 for xen on squeeze dom0 and domu (see addendum 1)

I managed to pci hide the 2 ports (see addendum 2)

If not using the iommu=soft I get a FW issue on the 3ware driver (addendum 3)

The pci looks passing through (addendum 4) but I get no drives behind

I copied /lib/modules/2.6.32-5-xen-amd64 fom Dom0 disk to Domu disk, I do not think about driver issue.

The passed thought device is claimed by driver: 3w-9xxx in Domu with lcpci –vv.

If I’m using the option iommu=soft I get a kernel krash at boot (Addendum 5)

And I can observe some troublesome message

[ 0.020372] PCI: System does not support PCI

[ 0.022547] pnp: PnP ACPI: disabled

The worst is the Dom0 has no problem with the 2 pci devices when no hidden.

Dom0 uses exactly same /boot/vmlinuz-2.6.32-5-xen-amd64 and /boot/initrd.img-2.6.32-5-xen-amd64

I'm wondering if my CPU is not too old (addendum 6)

Or If I missed some important steps in my conf.

Note I know all is working if I pass the disk raw from dom0 to domu with disk = [phy:/right path] but I don't feel this is "clean"; lots of I/O through Dom0 and not secure to Dom0 (risk of over writes).

Thank you for any hints.

Sincerely
