Trong file /etc/nova/nova.conf cấu hình như sau:
Lưu ý: Các option có [IP Controller] thì phải bind vào IP của Controller đang cấu hình. Vì nếu không bind vào IP cụ thể thì các service sẽ bind 0.0.0.0, như vậy nova sẽ không thể mở port được do haproxy đang bind VIP:8774, VIP:8775, VIP:8778, VIP:6080.

Sử dụng lệnh sau để xem Compute Node có hỗ trợ ảo hóa không
egrep -c '(vmx|svm)' /proc/cpuinfo
Nếu giá trị trả về >= 1 thì Compute Node hỗ trợ tăng tốc phần cứng. Nếu giá trị trả về = 0 thì Compute Node không hỗ trợ tăng tốc phần cứng, bạn phải cấu hình libvirt sử dụng QEMU thay KVM trong file /etc/nova/nova-compute.conf
[libvirt]
