[Qemu-devel] [Bug 1021649] Re: qemu 1.1.0 waits for a keypress at boot

The patch at http://permalink.gmane.org/gmane.comp.emulators.qemu/162828
fixes it for ioeventfd=on (the bug is that the ioeventfd is not added to
the select() arguments), but I and Avi disagreed on whether
ioeventfd=off works. :)

Jamie/Richard/Georg, can you test your respective reproducers without
any patch but with -global virtio-blk-pci.ioeventfd=off?

Title:
  qemu 1.1.0 waits for a keypress at boot

Status in QEMU:
  Confirmed
Status in “qemu-kvm” package in Debian:
  Confirmed

Bug description:
  qemu 1.1.0 waits for a keypress at boot.  Please don't ever do this.

  Try the attached test script.  When run it will initially print
  nothing, until you hit a key on the keyboard.

  Removing -nographic fixes the problem.

  Using virtio-scsi instead of virtio-blk fixes the problem.
