What IRQ is the sky2 using when assigned to the host? Is it really a
shared IRQ (I bet not as it should be using MSI)?
Also, check in the libvirt logs what qemu-kvm reports on the console.

The output from 'cat /proc/interrupts' directly after boot is in the
sky2.interrupts.
The relevant line from the output is
35: 0 0 0 0 1
0 0 0 PCI-MSI-edge sky2@pci:0000:04:00.0
So it looks like it is using MSI (although I don't have clue what that
means).
The log file for my domain (the name is "other") is attached in "other.log"
In the log file I see:
No IOMMU found. Unable to assign device "hostdev0"
Does this mean that I don't have IOMMU available on my laptop? The
output from 'dmesg | grep -i IOMMU' showed that Intel-IOMMI was enabled,
but perhaps that means only that the IOMMU option is activated but not
that it is really functioning.
It must be either (1) Intel VT-d available on my laptop and there is
some configuration/software problem or (2) The output from dmesg is
misleading. What do you think?
Cheers
Erik
