[Xen-devel] pci passthrough error "unknown command"pci-ins"

[Weald Wind <wealdwind@xxxxxxxxx>]

Hi All,

Please help me.

I am now installing the XEN on my PC and trying to config the pci pass through.

My motherboard is intel DQ45CB which is vtd enabled.

I downloaded the latest xen4.0 source from xen.org which is the latest release.

I downloaded stable-2.6.32-x dom0 kernel source from jeremy's repository.

After compiling the xen and dom0 kernel, I could play it. I could create hvm. And the VM was runing very well.

But when I configured the pci pass through, it always failed with  the following error:

root@charles-dq45:/opt/virtualmachines# xm pci-attach 1 0000:02:00.0

Error: Failed to assign device to IOMMU (0000:02:00.0@100,msitranslate=1,power_mgmt=0)

Usage: xm pci-attach [-o|--options=<opt>] <Domain> <domain:bus:slot.func> [virtual slot]

Insert a new pass-through pci device.

platform_fixed_ioport: changed ro/rw state of ROM memory area. now is rw state.

when I compiled the xen-tools, it's said the pci pass has been enabled...
