By default devstack uses the libvirt driver. This can be qemu or kvm<br>
depending on whether or not you are running on hardware or a virtual<br>
machine. You are able to run different drivers with different compute<br>
nodes - for example you can run a xen, hyperv or vmware driver<br>
(<a href="https://wiki.openstack.org/wiki/NovaVMware/DeveloperGuide#vSphere_Environm" target="_blank">https://wiki.openstack.org/wiki/NovaVMware/DeveloperGuide#vSphere_Environm</a><br>
ent_and_Inventory). You you want to run multiple compute nodes with<br>
different hypervisors you can make use of image meta data that will<br>
indicate to the scheduler which hypervisor it can choose.<br>
Thanks<br>
