[Bug 639712] Re: PCI Pass Through via libvirt cannot remap IRQ's
I was able to assign a PCI device to a VM via PCI pass through/vt-d with Wily/4.2 after adding 'intel_iommu=on' to the kernel cmdline. Can you please re-test with this option and the latest kernel to see if this works now?

[Bug 639712] Re: PCI Pass Through via libvirt cannot remap IRQ's
I'm trying with 12.04 LTS KVM host and guest.
RHEL 6 documentation says: {{ Secure device assignment also requires
interrupt remapping support. If a platform does not support interrupt
remapping, device assignment will fail. To use device assignment without
interrupt remapping support in a development environment, set the
allow_unsafe_assigned_interrupts KVM module parameter to 1. }}
and I get in dmesg:
[ 5556.500176] kvm_iommu_map_guest: No interrupt remapping support,
disallowing device assignment. Re-enble with
allow_unsafe_assigned_interrupts=1 module option.
Easy to create
/etc/modprobe.d/kvm.conf containing
options kvm allow_unsafe_assigned_interrupts=1
However, there is CVE-2011-1898 which this makes your system vulnerable
to see:
