What happened
: KT Cloud 대상으로 MapUI로 MCI 생성 후 MCI control 테스트를 진행할때 아래와 같은 현상이 나타납니다.
(참고로, Ubuntu 22.04 VM 5개로 이루어진 MCI임)

VMSpec : 4x16.itl (4v CPU, 16Gb Mem)
Image : b4034d6b-b96e-400d-b583-5d060156da98, ubuntu-22.04-64bit-20250325

O Issue 1) MCI suspend가 정상적으로 완료된 후 resume을 요청하면 실제 VM이 정상적으로 resume 되었는데 MapUI는 'Suspended' 상태로 머물러 있음. CB-SP AdminWeb UI로 확인해도 VM들이 다시 구동되어 runnig 하고 있는 상태여서 status 값은 정상적으로 체크됨.

  • Suspended 상태에서 Resume 요청 후 MapUI에서 ...

  • Resume 요청 후 console에서 확인

  • Resume 요청 후 CB-SP AdminWeb UI로 확인

  • 이 상태에서 MapUI에서 Resume을 다시 요청하면 정상 상태(Running 상태)로 나타남.

O Issue 2) MCI가 running 상태에서 Reboot 요청시, reboot이 실행되지 않고 그대로 있음. Log message를 보면 skip 한다고 나옴. Log 마지막 line을 보면 reboot이 성공적으로 완료되었다고 나옴.
