[Bug 1916775] [NEW] Guest freezes until there is a keyboard input on Windows version

[Abdurrahim]

Public bug reported:

I am using Qemu for Windows and when I try to run this for Windows
guests then the guests are freezing and waiting for keyboard input and
it continues to function after I press a key. I am using Windows10 Home
and below is the command I use to run the guest. I have suspected if
this is caused by random entropy but even with mouse moving it gives
same random locks and it continues to work as soon as I press a key so
maybe its not about entropy at all,
