Public bug reported:
Related to bug 1308341. Multi-cpu systems are experiencing guest kernels
hanging/crashing (both windows & linux guests) in kernel 3.13. (Windows
guests are getting bluescreens, linux guests just seem to be locking
up).
Downgrading to 3.12 eliminates the problem.
Filing new bug to provide data per apport-collect's suggestion.
