Confirmed on 12.04. Enabled IOMMU, now virt-manager complains:
Error starting domain: internal error Process exited while reading console log
output: char device redirected to /dev/pts/2
Failed to assign device "hostdev0" : Operation not permitted
kvm: -device
pci-assign,host=02:00.0,id=hostdev0,configfd=20,bus=pci.0,addr=0x6: Device
'pci-assign' could not be initialized
Traceback (most recent call last):

libvirtError: internal error Process exited while reading console log output:

On a side node, virt-manager should most likely be modified to disable/grey out
certain features if IOMMU is disabled.
