[Qemu-devel] [Bug 1717708] Re: QEMU aarch64 can't run Windows ARM64 iso's

[Shannon Zhao]

The virtio-gpu is not Linux specific. If windows could include the
device driver, it can be used on windows as well like other virtio
devices on windows x86.

I'm not sure what's the requirements for booting Windows on ARM64 virt
machine since the OS is not open source. So it would be better someone
from MS solves this problem or points what we missed for support
Windows.

Title:
  QEMU aarch64 can't run Windows ARM64 iso's

Status in QEMU:
  New

Bug description:
  Hi,
  recently Windows ARM64 ISOs have been posted on the internet..
  just checked with latest QEMU 2.10 release from 
  https://qemu.weilnetz.de/w64/qemu-w64-setup-20170830.exe 
  "h:\qemu\qemu-system-aarch64.exe" -boot d -cdrom 
h:\iso\16353.1000.170825-1423.RS_PRERELEASE_CLIENTPRO_OEMRET_ARM64FRE_ES-ES.ISO 
-m 2048 -cpu cortex-a57 -smp 1 -machine virt
  seems no video output..
  checked various machine options for example versatilepb (says guest has not 
initialized the guest)..

  so don't know if it's a QEMU bug or lacking feature but can support
  running Windows ARM64 builds (would be nice if you can add a
  Snapdragon835 machine type which is which first machines will be
  running..)

  
  note running a Windows x64 ISO with similar parameters works (removing -cpu 
and -machine as not needed)

  thanks..
