Oh, a mixed estate
I thought we were going to be investigating hypervisor stacking.
Running KVM on Hyper-V under VMWare ESX, just for a laugh...
When asked to write about the pros and cons of deploying multiple hypervisors, my first thought was that nobody in their right mind would want to do such a thing, especially if the software was from different vendors. Management would be a nightmare and so would all kinds of compatibility issues. On further investigation, it …

Disk is cheap, time is expensive.
