That is interesting Tim.<br>
<br>
Why Hyper-V if I may ask? Why not stick just with KVM?<br>

<p class="MsoNormal">Interesting topic, since you're
already running Hyper-v and ESX, I'm inferring that
your workload is heavy on windows VMs.<br>
If you're doing majority windows, and minority linux,
stick with hyper-v. The benchmarks I've read show that
windows VMs run fastest on hyper-v VS all others.<br>
If you expect an even split, it might make sense to
create Host Aggregates of various hypervisiors like
hyper-v and KVM, and utilize extra-specs in the
flavors and guest images to aid in scheduling, for
example "Windows images launch on the hyper-v pool"<o:p></o:p></p>
