Hello,
We are running vSphere 5.1 build 799733 hosts and i managed to create a VM (Windows 2008 R2 OS) that completely crashes hosts (purple screen) during shutdown of the VM or during vMotion (possibly other actions as well). It isn't normal behaviour of course, but i just wanted to double check here if this is a major or minor concern for VMware. I mean a VM coming through the hypervisor to crash any host it is running on... it does sound major to me.
