Title:
  Guest freezes until there is a keyboard input on Windows version

Status in QEMU:
  Invalid

Bug description:
  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,
