You could be referring to the following edk2 build ("5.fc27"):

  edk2-20170209git296153c5-5.fc27
  https://koji.fedoraproject.org/koji/buildinfo?buildID=944595

The edk2 base for this build is almost a year old; please try a newer
build; for example

  edk2-20171011git92d07e4-2.fc28
  https://koji.fedoraproject.org/koji/buildinfo?buildID=1000604

or else the "edk2.git-ovmf-x64" package from

  https://www.kraxel.org/repos/jenkins/edk2/

Specifically, the following OVMF bug comes to mind (although I'm not
sure it applies to your setup -- you seem to be using i440fx, not q35):

  https://bugs.launchpad.net/qemu/+bug/1715700

The following was also Windows related:
