This is how KVM_CAP_ works:

KVM_CAP_DEVICE_ASSIGNMENT in kvm.h
- kvm.ko returns nonzero to ioctl(KVM_CHECK_EXTENSION,
KVM_CAP_DEVICE_ASSIGNMENT) if it supports device assignment (recent
enough module, iommu found)
- userspace runs device assignment code only if above ioctl passes
We need something similar to deassignment, since it didn't arrive at
the same time as assignment.
In my patches, deassignment already does the similar thing as assignment. Can
you point out where it is missed?
It needs a new KVM_CAP_ symbol. 2.6.28 has KVM_CAP_DEVICE_ASSIGNMENT
defined, but will not have the deassignment code.
