Comment 5 for bug 1662865

I ran into this during a recent execution of the os_nova.yml playbook. An update to the latest stable/newton release did not fix the problem, as suggested earlier. It may in fact prevent the problem from occurring if you upgrade before getting into this state, but it did not do anything to get me out of the state once I got there.

My eventual solution was to manually apt-get install the older qemu packages to bring them up to the same version of those that the playbook had installed/updated.
