一旦執行不停機 Migrate VM,雖然 migrate 成功,不過 VM 會有幾項異常發生:
什麼是 PVM, HVM, HVM PV
PVM:
The paravirtualized template contains a kernel that is recompiled to be made aware of the virtual environment. It runs at near native speed, with memory, disk and network access optimized for maximum performance.
HVM PV:
The hardware virtualized template contains a kernel that is not recompiled for the virtual environment, but contains additional paravirtualized (PV) drivers for improved performance.
如果沒有成功,且 job 也沒有結束,在選擇執行 Kill 前必須先 abort 卡住的 job;否則可能造成 使用 Kill 也無法強制關閉 VM。
NOTE: 一旦遇到無法強制關閉 VM 時,可參閱 Q & A。
