Currently that device is built on x86 and ARM, but not powerpc, although powerpc does support both KVM and VFIO. This makes things awkward in userspace Currently qemu prints an alarming error message if you attempt to use VFIO and it can't initialize the KVM VFIO device. We don't want to remove the warning, because lack of the KVM VFIO device could mean coherency problems on x86. On powerpc, however, the error is harmless but looks disturbing, and a test based on host architecture in qemu would be ugly, and break if we do need the KVM VFIO device for something important in future. There's nothing preventing the KVM VFIO device from being built for powerpc, so this patch turns it on. It won't actually do anything, since we don't define any of the arch_*() hooks, but it will make qemu happy and we can extend it in future if we need to.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- xenial' to 'verification-done-xenial'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.
