I have read wiki http://docs.openstack.org/trunk/openstack-compute/admin/content/hyper-v-virtualization-platform.html to install nova-compute and configure in hyper-v. Now I have two question: 1, what about nova.conf in controller if my compute node is running hyper-V, is it the same as running KVM using libvirt? 2. Do one controller can control two compute nodes, one is kvm and the other is hyper-V?
