nova DB 마이그레이션

su -s /bin/sh -c "nova-manage db sync" nova

프로세스 재시작

service nova-api restart

service nova-cert restart

service nova-consoleauth restart

service nova-scheduler restart

service nova-conductor restart

service nova-novncproxy restart

sqlite DB 파일 삭제

rm -f /var/lib/nova/nova.sqlite

Nova Compute 노드 설치하기

apt-get install nova-compute sysfsutils

vi /etc/nova/nova.conf

컨트롤러설정과 동일

컴퓨트 노드가 하드웨어 가속을 지원하는지 확인.

egrep -c '(vmx|svm)' /proc/cpuinfo

vi /etc/nova/nova-compute.conf

[DEFAULT] compute_driver=libvirt.LibvirtDriver [libvirt] #virt_type=kvm virt_type=qemu

service nova-compute restart

rm -f /var/lib/nova/nova.sqlite

설치내용 확인

컨트롤러 노드에서 아래명령 실행

source admin-openrc.sh

nova service-list

nova endpoints

nova image-list
