[Bug 1723731] Re: Qemu turns to black screen while starting to copy installation files of Windows 7

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to another 
system. For this we need to know which bugs are still valid and which could be 
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state 
back to "New" within the next 60 days, otherwise this report will be marked as 
"Expired". Or mark it as "Fix Released" if the problem has been solved with a 
newer version of QEMU already. Thank you and sorry for the inconvenience.

Title:
  Qemu turns to black screen while starting to copy installation files
  of Windows 7

Status in QEMU:
  Incomplete

Bug description:
  Distribution: Arch Linux, Kernel: linux-4.13.5, Qemu: 2.10.1, OVMF: git 
(built 06.10.17).
  Steps to reproduce: create Qemu VM with such config:

  QEMU_VM_NAME=$(basename $(dirname "$0")) #Qemu virtual machine name (taken 
from working directory)
  QEMU_WORKING_DIR="$(dirname "$0")" #Qemu current working directory
  DIF=12 #set 2-digit number here
  QEMU_MONITOR_PORT=370${DIF} #Qemu monitor port
  QEMU_SERIAL_PORT=371${DIF} #Qemu serial port
  QEMU_PARALLEL_PORT=372${DIF} #Qemu parallel port

  qemu-system-x86_64 -daemonize -display gtk -boot menu=on -monitor 
telnet:127.0.0.1:${QEMU_MONITOR_PORT},server,nowait -serial 
telnet:127.0.0.1:${QEMU_SERIAL_PORT},server,nowait -uuid

  After that connect to Qemu console, insert Windows 7 installation
  media and start installation. You can successfully choose language,
  keyboard layout and partition your harddrive but after 2-3 seconds
  after beginning of copying installation files the graphical console
  screen turns to black and 1 CPU core on the host raises to 100%
  permanently and nothing happens. But if you installed Windows 7 before
  - there is no problems with VM. Tested on GTK, SDL types of screen.

  Qemu was installed from official repo and also I tried with built by
  myself version. Other OSes: Windows 8, 8.1, 10, Arch Linux, Debian,
  FreeBSD installed successfully.

  It happens only in OVMF-mode. I've just tested BIOS mode with no
  problems.
