[Openstack] where nova-compute runs: KVM vs Xen

2012-04-05 Thread Yun Mao
Right now, if you use KVM via libvirt (the default case), on the compute node, nova-compute runs on the host. If you use Xen via xenapi, nova-compute runs on Dom-U. (I'll ignore Xen via libvirt since no one really uses it.) What's the fundamental design decision to make the distinction?
