[Qemu-devel] [Bug 1589257] Re: Boot with OVMF extremely slow to bootload

I've solved the problem by using the ovmf package in apt instead of the
firmware I've had before. Apparently, the older firmware was only
compatible with an older kernel, and a newer kernel with the older
firmware would cause the issue.

  Boot with OVMF extremely slow to bootloader

Status in QEMU:

Bug description:
  I have used Arch Linux in the past with the same version (2.5.0), the
  exact same OVMF code and vars, and the exact same VM settings with no
  issues. Now with Ubuntu, I am having the issue where boot up until
  Windows takes about 10x longer. Every CPU thread/core allocated gets
  used 100% while this is happening. After that, everything operates as
  normal. There is no abnormal logs produced by qemu, or I don't know
  how to debug.

  Here are my settings:

  Ubuntu 16.04
  Qemu 2.5.0
  Relevant configs attached

  Windows 10
  VirtIO raw disk image
  VirtIO network
  Typical VGA passthrough setup, everything operating normally
