You can reproduce it by downloading this:

https://git.kernel.org/cgit/utils/kernel/virtme/virtme.git/commit/?h=crash-virtconsole&id=c55df415154e6331a1dc96a5e2ffcf5c684fc2f9

and running:

./virtme-run --installed-kernel 3.13.7-200.fc20.x86_64 --console
--qemu-opts -m 2048 -smp 2

Adjust the requested kernel version as appropriate.
