ubuntu_kvm_unit tests fail with exeception after intel-iommu.c

[Sean Feole]

The ubuntu_kvm_unit tests all appear to fail across all instance types during the runtime of the kvm_unit tests. It's a fairly vanilla msg, theres no output of value initially. It would appear that whatever runs after intel-iommu is making this throw an exception.

Logs for Bionic

It would appear after looking closer that there are indeed 2x separate failures for Xenial and Bionic, both occuring at different points in time runing the tests, however all of the instance types in the series will fail at the same point.
Again, same type of failure, rather vague... the test will need to be run by hand in order to identify it, as the logs did not record the crash dump.
