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

[Alexander Kuzmin]

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

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.

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.

[Expired for QEMU because there has been no activity for 60 days.]
