Do you see any IOMMU faults in dmesg on
the host around this error?
No, the only messages produces by IOMMU occurred at boot time.
Does nouveau work?
Not really. When I load the nouveau module in the guest I have the
following messages:

0000:00:03.0 failed with error -16
So I don't know what it the error -16 but when I try to start an X
server it starts well and finally complains about KMS that is not
enabled. I checked in the config file and CONFIG_FRAMEBUFFER_CONSOLE is
set to y.
As KMS seems required by the nouveau driver, X failed to use nouveau.
