Hi Mike, We run VCL on top of OpenStack on top of Ubuntu 12.04 and KVM. We did recently migrate away from ESXi to the OpenStack cluster. Our VCL system currently only uses Windows 7 images with virtio drivers. We have not had any virtualization issues (that I know of).
I can't comment on performance differences, but I much prefer KVM, though am biased towards Unix/Linux. :) Thanks, Curtis.
