[Xen-users] Upgrade XEN to 4.0.1: AMD-Vi: IOMMU not found! - I/O virtualisation disabled (PCI-Passthrought didn't work again)
Hello XEN-User,
I have made a system upgrade debian lenny to squeeze it works fine.
So Xen also get upgraded to 4.0.1. Some fixes with config (sda ->
xvda, tty -> hvc0 ...) and everything works well for DomUs.
One thing left: One DomU uses bevore upgrade pcipassthrough and
everything worked well. After the upgrade it doesn't - because
pcipassthrough could not get the pci-device from Dom0 to DomU. After
creation of the DomU there is the error: Error: pci:

AMD-Vi: IOMMU not found! and I/O virtualisation disabled instead of
enabling virtualization in BIOS (Motherboard:
Gigabyte MBAM3 AMD-880G GA-880GMA-UD2H
with BIOS F1). This Version has worked under previous version
of xen. Search in some threads mean to update BIOS maybe the
solution. BIOS updated to f6f (newest version), but nothing change.
Deactivate and save, activate and save the virtualisation in BIOS no
change.
Try some settings iommu=verbose iommu=1
iommu_inclusive_mapping=1 amd-iommu-debug
no change. Modul pciback is also included in
/etc/initramfs-tools/modules and used to generate new initrd.
I am searching for days - but no solution yet. Maybee someone could
help me or give me a hind for this. Any idea?
kind regards
Marius Meisner
PS: CPU is vt-able:
AMD
