RedHat 에 OpenStack 및 기타 테스트 환경을 위해 IPMI 가 필요할때가 있습니다.
VM 에 IPMI가 있을리 만무 하죠.
가상으로 IPMI(iLO, iDRAC ) 를 만들어 봅시다.
전제조건
RedHat 8.4.
root 사용자로 작업.
# yum install libvirt-ptyhon3
[root@lab2 ~]# dnf install libvirt-python3

VM이 start 되었을까요?
KVM ( virt-manager )를 보면 안켜져 있습니다.
자 vbmc는 VM에 대한 전원을 ON/OFF 할 수 있습니다. 이는 ipmitool을 통해 진행 됩니다.
#ipmitool -I lanplus -U zeljko -P pass -H 127.0.0.1 -p 7110 power up
[root@lab2 /]# ipmitool -I lanplus -U admin -P 1234 -H 127.0.0.1 -p 7110 power up

#ipmitool -I lanplus -U admin -P 1234 -H 127.0.0.1 -p 7110 power down
VM 이 OFF 됩니다.
