Steve - can you try using the generic flavour as your hypervisor ? The
lowlatency flavour has never been vetted for virtual environments.

Title:
  Virtual machines hang in kernel 3.13

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  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.
