Thanks Peter for your help as well as your suggestion. I have got the cues of this \
issue.
Current there still exist another issue that confuse me that we random hit VM can't \
boot and stuck in black screen show as "Guest has not initialized the display \
(yet)."
The attachment is the Libvirt debug log but I'm not able to find any useful cues. \
Any comments regarding this issue will be appreciated.
