At CERN, we run KVM and Hyper-V. Both work fine. Depending on the size of your cluster, you may have other factors to consider such as monitoring and configuration management. We use Puppet to configure both environnments.
Images are tagged with a property hypervisor_type which is used to schedule workloads to the appropriate hypervisor.

The benchmarks I've read show that windows VMs run fastest on hyper-v VS all others. 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" > On Mar 18, 2015, at 2:41 PM, Vytenis Silgalis > <[email protected]<mailto:[email protected]>> wrote: > > Hello, > > I'm looking to champion openstack at my company, we currently run both a > small hyper-v cluster and 3 VMware clusters.
