[ikvm] Centos enters blank screen when keeping pressing certain key

[Heyi Guo]

Hi,

Test ikvm with Centos stream 9, and configure "Power Saving 
Options"->"Screen Blank" with 1 minute, we found ikvm will enter blank 
screen when we keep pressing one certain key, like space key. However 
the situation won't happen when using a physical USB keyboard.

Is there anyway to keep active from the point of view of the host OS for 
this test case?

Thanks,

Heyi
