B-3-1. CPU 가상화 지원 여부 확인

root@rocky-nova01:~# egrep -c '(vmx|svm)' /proc/cpuinfo
48

결과 값이 0일 경우 아래와 같이 설정한다.

# sed -i "s/virt_type=kvm/\#virt_type=kvm/g" /etc/nova/nova-compute.conf
# echo "virt_type = qemu" >> /etc/nova/nova-compute.conf

B-4. nova pkg 를 재기동한다.

root@rocky-nova01:~# service nova-compute restart

C. 확인

C-1. Controller node에서 admin_openrc 환경변수 파일을 loading한다.

root@rocky-osc:~# source ~/admin_openrc

C-2. nova compute 리스트를 확인한다.

root@rocky-osc:~# openstack compute service list --service nova-compute
+----+--------------+--------------+------+---------+-------+----------------------------+
| ID | Binary       | Host         | Zone | Status  | State | Updated At                 |
+----+--------------+--------------+------+---------+-------+----------------------------+
| 13 | nova-compute | rocky-nova01 | nova | enabled | up    | 2019-03-07T08:56:29.000000 |
+----+--------------+--------------+------+---------+-------+----------------------------+

C-3. nova 명령어를 이용하여 compute node의 host를 확인한다.

root@rocky-osc:~# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
Found 2 cell mappings.
Skipping cell0 since it does not contain hosts.
Getting computes from cell 'cell1': 12a5c5d5-26b6-46da-9458-5c116e0743d9
Checking host mapping for compute host 'rocky-nova01': a4868098-f27b-4a75-8488-5942ded945cf
Creating host mapping for compute host 'rocky-nova01': a4868098-f27b-4a75-8488-5942ded945cf
Found 1 unmapped computes in cell: 12a5c5d5-26b6-46da-9458-5c116e0743d9

새 노드를 추가할때 controller node에서 아래 명령어를 실행해야 한다.

root@rocky-osc:~# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

또는 /etc/nova/nova.conf 에 등록하여 특정 주기별로 노드를 추가 한다.

root@rocky-osc:~# vi /etc/nova/nova.conf
~ (생략)
[scheduler]
discover_hosts_in_cells_interval = 300
~
