Ceph can perform well, but it depends on ha= rdware, architecture, and configurations (as any technology). KVM is the sa= me deal, it performs well and it is stable. Just to be clear, there are many production environments running with KVM a= nd Ceph out there; if hyper-converged fits well with your needs it sure can= be applied with CloudStack + KVM + Ceph.
