Hi Guys,
Who can give me a help?
I recently hit the issue that VM can’t boot correctly and show black screen as 'Guest has not initialized the display (yet)’ as below picture
Qemu version in our system is 5.1 and host os is rehat 7.4. kernel version is 3.10.0-693.el7.x86_64.

That is confuse me for long time. What the potential issue are? Any comments are appreciated.
