"INTx fd" busy error on VM startup at boot, subsequent startup okay
...it afterwards works fine. This is
on a Ubuntu Wily i7-4790 box running Linux 4.2 and libvirt 1.2.16.
There is a legacy (5V) PCI card being passed through to the VM, the
error seems to relate to that.
The error that always appears at boot in
`/var/log/libvirt/qemu/test-vm.log` is:

Cannot turn iommu on inside guest
...<driver intremap='on'/>
</iommu>
</devices>
or just a simpler
<devices>
<iommu model='intel /'>
</devices>
However, when I try to boot it, it crashes with the following error
message (stolen from /var/log/libvirt/qemu/testkvm.log):
2020-02-11T05:13:27.278707Z qemu-system-x86_64: We need to set
caching-mode=on for intel-iommu to enable device assignment with IOMMU
protection.
2020-02-11 05:13:27.577+0000: shutting down, reason=crashed
that sounds like it wants me to do something like
