Bug description:
  Hi,

  Corporate environment, Windows XenU platforms, using QEMU HVM (qemu-
  system-x86) on multiple Ubuntu Xen0 platforms.  Established stable
  production environment (for > 1-5 years), Ubuntu and Windows nodes
  getting latest patches etc.  Dell R6XX series server hardware.

  After updates from mainline: 1:2.5+dfsg-5ubuntu10 to 1:2.5+dfsg-
  5ubuntu10.22 a reboot of XenU VMs very slow and repeated
  BlueScreening.

  Windows Server 2012, does come up after 4+ minutes booting.

  
  Windows Server 2008R8, Windows 7 Pro, Windows 10 Pro VMs fail to boot with blue screen "framebuf" STOP.  (PNG available).

  Boot to safe mode (very slow ~ 4mins to login screen) and remove video
  drivers, reboot succeeds, windows drivers auto updated, reboot fails.

  
  Testing completed on Windows Server 2008R8 images including migration of VM Disk devices to other Dell rack servers:

  o Xenial Xen0 server - Same issues
  o Trusty Xen0 server - Same issues
  o Precise Xen0 server - Fast boot / no issues

  On Xenial systems, downgrading qemu-system-x86 to version 1:2.5+dfsg-
  5ubuntu10 reverts to previous performance / stability (~25 secs to
  loginscreen) = all good.

  Tested PPA versions of qemu-system-x86 with local dpkg installs,
  version ubuntu10.21 works fine,  ubuntu10.22 fails. Proposed
  ubuntu10.23 also fails.

  
  QEMU Command line used (unchanged between good and back observations):
